Videogrammetry refers to utilizing specific methods and software capabilities for rapidly collecting continuously geo-referenced video from remote sensing platforms and extracting still image frames (as opposed to traditional still image photo cameras). These video-derived photo datasets are then used to build orthomosaics and 3D maps and models in traditional geospatial photogrammetry processing software.
Advantages over traditional photogrammetry methods include faster, less precise data collection techniques and more rapid post-processing times.
Remote GeoSystems software adds value the videogrammetry process with our patented methods for geotagging, “geoediting” and extracting still frame photos referenced with enhanced geospatial metadata optimized for processing with 3rd-party 3D photo modeling and photogrammetry softwareMap-based Video Geotagging & Video Geoediting
Virtually any video can be continuously georeferenced with a GPS data log using our software’s video geotagging features. Then using the video geoediting features in LineVision Desktop – Ultimate edition and Video GeoEditor, users can intuitively click on the GPS video track on the map to select, cut, trim and stich portions of the geospatial video segment so a new georeferenced video clip is created with only the content needed for your image extraction project. Unlike other video editing techniques, our patented process keeps the GPS metadata synced with the newly edited video throughout the editing process.MISB FMV & Camera Target Footprint Metadata
For video data that includes embedded MISB FMV or STANAG-spec KLV metadata, users have the option of extracting all the relevant location metadata representing the camera target frame center and field of view footprint on the map.
For many DJI drone models, our software offers users the ability to leverage the Flight Record Log to estimate and extract metadata for where the UAV’s gimbal camera target frame center and field of view footprint is showing on the map.Simple User-defined Photo Extraction from Video
Our videogrammetry photo extraction interface allows users set both the time period and the frames per second (FPS) frequency at which to automatically capture geotagged images from the video. These images are sequentially numbered and accompanied with the metadata output in tabular format for ingest into 3D mapping and modeling software.
