-====== Image Annotation to Object ======
-FIXME
-This page describes how to use the extension "Image Annotation to Object"\\
-{{orbit_desktop:how_to_find.png?25&nolink  |}} [[dev:desktop:workspace:main_toolbar|Main Toolbar]] > Extensions > Image Annotation to Object
-The "Image Annotation to Object" extension makes it possible to convert image annotations expressed in pixel coordinates or bounds into 3D coordinates or 3D boxes using pointcloud resource.\\
-===== Concepts =====
-Image annotations can be defined for mapping run imagery in pixel coordinates and bounds. The image pixels are converted into 3D coordinates or 3D boxes in a vector file using the mapping run pointcloud.
-The 2D annotations and tags are overlayed on the opened image.
-===== Source =====
-==== Pixel Definitions ====
-Select how the annotations are defined:\\
-  * Coordinates: every annotation is defined by 1 coordinate
-  * Bounds: every annotation is defined by 2 pixel coordinates that form the bounds of the rectangle
-==== Reference Files ====
-Choose how the reference files are structured:
-  * One file for every image
-  * One file for all images
-Supported formats are .csv and .xml.
-===== Target =====
-After selecting the target file location and CRS, choose to create 3D point objects or boxes.
-===== Parameters =====
-===== 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.
-==== Search Dist Max ====
-The maximum distance from the camera to the detected object.
-==== Search Radius and Cluster Distance ====
-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.
-==== 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.
-==== Ground margin ====
-The ground margin used to identify a 3D box reached the ground to be able to end the clustering.
-==== Voxel Size ====
-The voxel size used to cluster objects.
-==== Voxel Pts Min ====
-The minimum number of points to have a voxel.
-===== Analyze =====
-===== Results =====
