Vision software expanded to operate in 3D point clouds

January 23, 2017 // By Julien Happich
EVT's EyeVision 3D software designed for the company's EyeScan 3D sensor series contains the commands of the Basic EyeVision image processing software version and a broad 3D command set for evaluating and measuring on 3D point clouds.

The 3D command set has roughly 40 commands. Included are commands such as "3D Blob" to count objects also in a point cloud. There is also the "3D Distance" command to measure distances. Additionally users have access to the "3D Position Adjustment" command which works as a planimetic adjustment. This can be used to adjust the position of an object so that for example a robot arm will grab the object in the same position as the previous one even when it does not arrive on the conveyor belt in the exact position.

Additionally the 3D-software now also has a "RectProbe" command to probe edge-points in a certain direction and returning the detected edge. This can be useful for numerable further measurements on the point cloud. There are also various filter commands such as "Merge", which merges two point clouds into one, or the filter command "Outlier Removal", which removes all points that deviate in Z-direction from their neighbors by a certain amount. Important is also the "Voxelgrid" filter, which down-samples a point cloud using a voxel grid and the output points are then the average of all points inside a voxel. The filter can make unordered point clouds into ordered.
