From Depth Map to Point Cloud
Function
This Step generates a point cloud from a depth map and a corresponding color image.
|
Comparison of Similar Steps: The Step Capture Images from Camera can also directly output point clouds and colored point clouds. However, the Step From Depth Map to Point Cloud features a higher processing speed in this regard. You can set an ROI in the depth map in this Step to lower the quantity of unnecessary point clouds and thus improve the processing speed. |
Usage Scenario
This Step is usually connected after the Step Capture Images from Camera and can generate point clouds from depth maps. You can set an ROI in the depth map in this Step to improve the processing speed.
