-====== Image Pixels to Objects ======
-FIXME
-This page describes how to use the extension "Image Pixels to Objects"\\
-{{orbit_desktop:how_to_find.png?25&nolink  |}} [[dev:desktop:workspace:main_toolbar|Main Toolbar]] > ... > > Extensions > Image Pixels to Objects
-The "Image Pixels to Objects" extension makes it possible to convert Image Pixel coordinates or bounds into 3D coordinates or 3D boxes.\\
-===== 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 ====
-Choose how the pixels are defined:
- * Coordinates: every pixel is defined by 1 pixel coordinate
- * Bounds: every pixel is defined by 4 pixel coordinates from a rectangle
-==== Reference Files ====
-Choose how the reference files are structured:
- * One file for every image
- * One file for all images
-===== Target =====
-Select the target file location and CRS.
-Choose to create 3D coordinates or 3D boxes.
-===== Parameters =====
-==== Cluster size ====
-The radius around the vector between camera position and pixel point to search for cluster points.
-Tooltip: The cluster size to identify coordinates in the direction from camera position to image position.
-===== Advanced Parameters =====
-==== Search Slice Thickness ====
-The thickness of the slices created from camera position to pixel point.  \\
-For creating 3D Coordinates:\\
-If a slice has an object, don't search in the following slices.\\
-For creating 3D Boxes:\\
-Do search in the following slices up until the Search Dist Max is reached.
-==== 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 detected 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.
-===== Analyze =====
-===== Results =====
