- | The "Image Pixels to Objects" | ||
- | |||
- | |||
- | ===== Concepts ===== | ||
- | |||
- | Image pixel coordinates and bounds can be defined for mapping run imagery. The image pixels are converted into 3D coordinates or 3D boxes in a vector file. | ||
- | |||
- | The 2D annotations and tags are overlayed on the opened image. | ||
- | |||
- | |||
- | |||
- | ===== Source ===== | ||
- | |||
- | ==== Pixel Definitions ==== | ||
- | |||
- | Coordinates | ||
- | Bounds | ||
- | |||
- | ==== Reference Files ==== | ||
- | |||
- | Define if there is one source file for every image or one source file for all images. | ||
- | |||
- | ===== Target ===== | ||
- | |||
- | Select the target file location and CRS. | ||
- | Choose to create 3D coordinates or 3D boxes. | ||
- | |||
- | ===== Parameters ===== | ||
- | |||
- | ==== Cluster size ==== | ||
- | |||
- | The cluster size to identify coordinates in the direction from camera position to image position. | ||
- | |||
- | ===== Advanced Parameters ===== | ||
- | |||
- | ==== Search Slice Thickness ==== | ||
- | |||
- | The thickness of the slice used to find an object in the direction camera to pixel position. | ||
- | If one slice has object, don't look in further slices. Only if there' | ||
- | |||
- | ==== Cluster Pts Min ==== | ||
- | |||
- | The minimum number of points to have a cluster. | ||
- | |||
- | ==== Search Radius (Box from Pix Coord) ==== | ||
- | |||
- | The search radius around the direction camera to pixel position to search for the 3D object. | ||
- | |||
- | ==== Search Dist Max ==== | ||
- | |||
- | The maximum distance from the camera to the object. | ||
- | |||
- | ==== 3D Box Creation - Ground margin ==== | ||
- | |||
- | The ground margin used to identify a 3D box reached the ground to be able to end the clustering. | ||
- | |||
- | ==== 3D Box Creation - Voxel Size ==== | ||
- | |||
- | The voxel size used to cluster objects. | ||
- | |||
- | ==== 3D Box Creation - Voxel Pts Min ==== | ||
- | |||
- | |||
- | The minimum number of points to have a voxel. | ||
