MANTIS and TTI Collaborate on GNSS Evaluation

The Measurement Analytics (MANTIS) Laboratory recently joined forces with the Texas A&M Transportation Institute (TTI) for a hands-on geospatial research experiment aimed at advancing the understanding of specific GNSS technologies. This collaborative effort brought together researchers and engineers from both teams to conduct a comparative field study of GNSS receiver performance across various grades and correction techniques.

The joint fieldwork took place on the Texas A&M University campus, where teams collected GNSS data over a known benchmark. The objective was to evaluate the feasibility, limitations, and practical applications of different GNSS configurations in the context of geospatial sciences, surveying and mapping, and transportation-related projects. By comparing the different setups, the researchers seek to quantify positional accuracy, reliability under varying environmental conditions, and overall cost-effectiveness.

Key considerations included accuracy and precision (how close each receiver-correction pair could measure relative to the benchmark), operational complexity (time, setup, and training required to deploy each system), and cost benefit (balancing budget constraints with positional accuracy needs). Findings are expected to inform best practices for selecting GNSS technologies based on project requirements, whether for asset inventory, roadway mapping, traffic infrastructure planning, or other geospatial applications where precise positioning is critical.

This collaboration underscores the value of interdisciplinary research and practical testing as MANTIS and TTI continue to bridge engineering and geospatial science to support innovation in transportation systems and beyond.

José Pilartes-Congo Defends Dissertation Proposal

MANTIS Ph.D. student José Pilartes-Congo recently defended his dissertation research proposal titled “Change Detection and Digital Twin Generation from Multi-Sensor and Multi-Scale 3D Data Fusion”.

——

His abstract read as follows:

Reality capture technologies incorporating 3D scanning and imaging techniques provide innovative and efficient means for measuring the geometric characteristics of built and natural environments. Common techniques include structure-from-motion / multi-view stereo (SfM/MVS) photogrammetry and lidar scanning, which provide dense and informative 3D point clouds, textured meshes, and digital elevation models (DEMs) that can be used to create digital records and repositories of geospatial data, thus supporting surveying and mapping efforts. These methods can be implemented on various remote sensing platforms such as uncrewed aircraft systems (UASs), traditional aircraft, or satellites to offer different extents of coverage, spatial resolution, and measurement accuracies. By facilitating accurate and effective monitoring of structural and environmental changes over time, these techniques can support a wide range of tasks such as project planning, asset management, and natural resource allocation. However, to effectively do so requires determining how to best exploit information captured in 3D data streams acquired from various remote sensing modalities, while addressing differences in data characteristics, measurement fidelity, and task suitability for different applications. This research explores the following question: How can reality capture (i.e., remote sensing) technologies providing 3D geospatial data at different perspectives, resolutions, geographical extents, and measurement fidelities be effectively and optimally integrated to support structural change detection and monitoring of built and natural environments? This research acknowledges that individual remote sensing modalities for acquiring 3D geospatial data have various advantages and limitations and examines ways to optimally fuse different datasets in a way that one complements the other, resulting in more informative and useful 3D geospatial datasets for change detection applications. With this consideration, this research explores data acquired from ground, air, and space, using photogrammetry and lidar scanning technologies, as well as associated algorithmic and processing techniques for data calibration, georeferencing, accuracy assessment, and data fusion for generating 3D digital twins of the environment. Ultimately, the research seeks to develop a digital twin framework able to ingest multi-sensor, multi-scale 3D data at different spatial resolutions and temporal frequencies, for geospatial change detection analyses to support surveying and monitoring activities, especially for transportation roadway corridors (built environments) and dynamic coastlines (natural environments).

José Pilartes-Congo Publishes Article in Drones

MANTIS Ph.D. student José A. Pilartes-Congo has recently published an article in Drones titled “Empirical Evaluation and Simulation of the Impact of Global Navigation Satellite System Solutions on Uncrewed Aircraft System–Structure from Motion for Shoreline Mapping and Charting”. The article focuses on empirical testing and simulated evaluation of different GNSS correction techniques on the accuracy of UAS-SfM products.

——

The abstract reads as follows:

Uncrewed aircraft systems (UASs) and structure-from-motion/multi-view stereo (SfM/MVS) photogrammetry are efficient methods for mapping terrain at local geographic scales. Traditionally, indirect georeferencing using ground control points (GCPs) is used to georeference the UAS image locations before further processing in SfM software. However, this is a tedious practice and unsuitable for surveying remote or inaccessible areas. Direct georeferencing is a plausible alternative that requires no GCPs. It relies on global navigation satellite system (GNSS) technology to georeference the UAS image locations. This research combined field experiments and simulation to investigate GNSS-based post-processed kinematic (PPK) as a means to eliminate or reduce reliance on GCPs for shoreline mapping and charting. The study also conducted a brief comparison of real-time network (RTN) and precise point positioning (PPP) performances for the same purpose. Ancillary experiments evaluated the effects of PPK base station distance and GNSS sample rate on the accuracy of derived 3D point clouds and digital elevation models (DEMs). Vertical root mean square errors (RMSEz), scaled to the 95% confidence interval using an assumption of normally-distributed errors, were desired to be within 0.5 m to satisfy National Oceanic and Atmospheric Administration (NOAA) requirements for nautical charting. Simulations used a Monte Carlo approach and empirical tests to examine the influence of GNSS performance on the quality of derived 3D point clouds. RTN and PPK results consistently yielded RMSEz values within 10 cm, thus satisfying NOAA requirements for nautical charting. PPP did not meet the accuracy requirements but showed promising results that prompt further investigation. PPK experiments using higher GNSS sample rates did not always provide the best accuracies. GNSS performance and model accuracies were enhanced when using base stations located within 30 km of the survey site. Results without using GCPs observed a direct relationship between point cloud accuracy and GNSS performance, with R2 values reaching up to 0.97.

Bradley Koskowich Defends Dissertation

MANTIS Ph.D. Candidate Bradley Koskowich successfully defended his dissertation, titled “An Assessment of Methods for Effective Single Camera Resection Solutions to the Cross-view Geo-localization Problem,” on Nov. 5, 2024. Bradley’s research focused on blending remote sensing products, platforms, and digital reality tools with AI techniques to connect the physical world directly with data. Bradley has developed several full-stack software applications for the Conrad Blucher Institute over the years.

——

The abstract of his presentation read as follows:

Typical multi-view stereo (MVS) photogrammetry problems have both traditional and deep learning solutions which utilize collections of overlapping imagery to solve for multiple camera positions simultaneously. Structure-from-motion (SfM) workflows achieve this using bundle adjustments, while simultaneous-localization-and-mapping (SLAM) solutions use a similar, pipelined adjustment method. More recent deep learning research such as neural radiance fields and Gaussian Splatting can also enhance typical MVS photogrammetry results, but all approaches still lean on a crucial operation, which is accurate camera position and orientation estimation, also called camera pose. Camera pose information can be collected via external hardware such as the global navigation satellite system (GNSS) and inertial motion units (IMU), derived in a post-processing phase from known ground control points, or estimated in a relative fashion between images. Anything other than relative estimation generally introduces additional cost, complexity, and potential points of failure which can render collected pose information useless. This dissertation addresses the challenges of using only computer vision to accurately compute camera pose independent of typical recording systems, focusing on the specific photogrammetry sub-problem of determining camera pose between single image pairs: one georeferenced aerial image and one terrestrial perspective image with unknown priors. Also called monoplotting, single camera resectioning, or cross-view geo-localization, it is technically a simpler camera configuration to solve than MVS photogrammetry, but it lacks the information density MVS photogrammetry methods usually leverage and is extremely sensitive to initial conditions, making it difficult to solve automatically.

In this dissertation, potential applications that can be built atop accurate monoplotting solutions are demonstrated and enhancements to both algorithmic methods and deep learning architectures for solving the monoplotting problem are explored. First, a practical application demonstrates monitoring vehicular traffic in a parking lot from an existing security camera installation in real time, powered by monoplotting. This practical application also illustrates the extreme sensitivity to initial conditions. Second, an algorithmic approach with a purpose-built feature matching method supported by GPU-accelerated feature extraction and data processing was developed and tested across a variety of environments to gauge its ability to mitigate sensitivity to initial conditions. Finally, insight into the behaviors of deep learning architectures which can partially solve the monoplotting problem was obtained by investigating the effects of replacing dense training collections of georeferenced & pose-tracked terrestrial imagery with historical aerial image collections, achieving comparable or better results with fractional training data compared to prior studies. A hybrid approach that combines deep learning for partial initialization with the algorithmic method is proposed, using less training data to improve computed pose accuracy in full 3D space. The broader impact of this research could allow systems that rely on camera pose estimation to do so in a way that provides it as validation or recovery mechanism independent of typical GNSS/IMU systems in the event of catastrophic failure.

The article focuses on utilizing a small uncrewed aircraft system (UAS) equipped with a multispectral sensor to assess various vegetation indices (VIs) for their potential to monitor iron deficiency chlorosis (IDC) in grain sorghum (Sorghum bicolor L.).

——

The abstract reads as follows:

This study uses a small unmanned aircraft system equipped with a multispectral sensor to assess various vegetation indices (VIs) for their potential to monitor iron deficiency chlorosis (IDC) in a grain sorghum (Sorghum bicolor L.) crop. IDC is a nutritional disorder that stunts a plants’ growth and causes its leaves to yellow due to an iron deficit. The objective of this project is to find the best VI to detect and monitor IDC. A series of flights were completed over the course of the growing season and processed using Structure-from-Motion photogrammetry to create orthorectified, multispectral reflectance maps in the red, green, red-edge, and near-infrared wavelengths. Ground data collection methods were used to analyze stress, chlorophyll levels, and grain yield, correlating them to the multispectral imagery for ground control and precise crop examination. The reflectance maps and soil-removed reflectance maps were used to calculate 25 VIs whose separability was then calculated using a two-class distance measure, determining which contained the largest separation between the pixels representing IDC and healthy vegetation. The field-acquired data were used to conclude which VIs achieved the best results for the dataset as a whole and at each level of IDC (low, moderate, and severe). It was concluded that the MERIS terrestrial chlorophyll index, normalized difference red-edge, and normalized green (NG) indices achieved the highest amount of separation between plants with IDC and healthy vegetation, with the NG reaching the highest levels of separability for both soil-included and soil-removed VIs.
