Object state
Summary
:
The first step simply consists of the point cloud pre-segmentation based on height values of the luminaire. Where all the points from the point cloud above the reference level are considered for the next stage. The stage 2, thresholds for classification are extracted from the color histogram analysis taken of 8-bit color images. Finally, is refined the existing segmentation of the luminaires using known values of vehicle speed (v) and camera shutter speed (t), and in this way calculate their centroids.
