Photogrammetry/Videogrammetry TRIZ Cases
- Trailer Coupler Distance Sensing with Camera-IMU Fusion
Monocular camera and IMU fusion estimate longitudinal, lateral, and vertical trailer coupler distance for more accurate real-time hitching.
- Airport Surface Data Fusion for Runway Incursion Detection
Correlating vehicle location timestamps with aircraft video builds richer training data for more accurate runway incursion detection.
- Runway Incursion Detection Using Correlated Vehicle and Video Data
Correlating vehicle location timestamps with aircraft video frames builds richer training data for more accurate runway incursion detection.
- Vehicle-Mounted Site Surveying With Robotic Staking and GPR
Automated vehicle surveying combines robotic staking, camera capture, and ground penetrating radar to cut manual site survey time and improve accuracy.
- UAV Route Planning for Accurate Ribbon-Target Aerial Surveys
Two aligned flight routes with different camera projection orientations shorten UAV surveys of rivers, roads, and pipelines while improving mapping accuracy.
- Adaptive Workflow Deployment for Device Issues and Task Reassignment
Software agents detect or predict device issues, then trigger workflow changes and task reassignment to keep work running.
- UAV Position Measurement Using Retro-Reflector Tracking Without GPS
A ground laser tracker and retro-reflector let a UAV keep position and measure large structures where GPS signals are blocked.
- UAV Blade Inspection Flight Paths With Pose-Linked Sensor Data
Automated UAV blade inspection links each image to pose data, improving defect localization, coverage, and digital documentation.
- Below-Canopy UAV Tree Diameter Measurement With LIDAR
Flying below the canopy, a UAV uses LIDAR and imaging to measure tree diameters accurately while cutting field time and manual sampling.
- Mobile 3D Surface Surveying With Structured Light Vehicles
Structured light from a second mobile vehicle adds detectable features, improving 3D surface surveying accuracy on optically uniform surfaces.
- Road Map Updating for Shielded Region Detection From Image-Map Differences
By comparing road regions from camera images and stored maps, this case filters shielded areas like tunnels and overpasses to avoid map update errors.
- Spacecraft Attitude Control for Blur-Free Imaging and Laser Downlink
Periodic pointing and immobilization keep optical and laser sightlines fixed, enabling sharp Earth imaging and efficient laser image transfer.
- Subsurface Utility Mapping Using Surface Markings and Image Analysis
Digital images and public works markings are combined to map buried utilities more precisely, reducing excavation damage risk.
- Leader-Controlled Imaging Device Program Switching Using Photogrammetry
Photogrammetry lets a leader device size target objects and switch follower imaging programs, avoiding slow, error-prone manual configuration.
- Focused 3D Point Clouds Through ROI Energy Pulse Scanning
A two-phase scan identifies objects across the FOV, then concentrates energy pulses on selected regions for richer point clouds.
- Rail Vehicle Digital Map Creation Using Onboard SLAM
Onboard sensors enable incremental mapping without external landmarks, reducing system complexity while maintaining localization accuracy.
- Vision and Millimeter Wave Fusion for All-Weather Target Detection
Fuses camera images with millimeter wave radar point clouds to enhance perception capabilities in complex environments.
- Aerial Image Mosaic Generation Using Selective Feature Matching
Selective matching of consecutive and non-consecutive image pairs establishes optical flow for aerial image mosaic generation.
