Title:
MULTI-OBJECT TRACKING BASED ON LIDAR POINT CLOUD
Document Type and Number:
WIPO Patent Application WO/2018/195996
Kind Code:
A1
Abstract:
Techniques, systems, and devices are disclosed for conducting object tracking a light detection and ranging (LIDAR) based object tracking system. In one exemplary aspect, the system includes a plurality of light emitter and sensor pairs operable to obtain data indicative of actual locations of surrounding objects, wherein the data is grouped into a plurality of groups by a segmentation module; and an object tracker configured to (1) build a plurality of models of target objects based on the plurality of groups, (2) compute a motion estimation for each of the target objects, (3) feed a subset of data back to the segmentation module for further grouping if the subset of data fails to map to a corresponding target object in the model, and (4) modify the model for the target object by adjusting the motion estimation to reduce or remove a physical distortion of the model.
