Menu: Analyze / Object detection
This tool is available with VisionLidar Premium and VisionLidar Ultimate versions only.
This function allows the user to detect similar objects in a point cloud. More then just detecting clusters, it tries to find the best shape of it and compare to a reference point cloud or mesh. The result is a list of detected object showing their percentage of compatibility.
The detection is done in multiple steps:
- First step is to specify the model. A file can be loaded or the model can be selected on screen.
Loadable models are either in Osg, Osgb, Pcd, Obj or Ply file format.
As for the option "From screen", a fence around the object must first be done to isolate it.
- Afterward the object can be "Show/Edit"ed to ensure it correspond to the user's need.
- Last "Detect similar" will lunch the detection with the specified parameters, filling the table below with each new detected object and reorder them by percentage of correspondence.
Like clusters, object detected can be draw, which will draw all the points from the detected object. It's also possible to draw the points of the model that served the detection of the object, allowing to see the difference between both objects.
