Abstract
An environment recognition system for a machine operating at a worksite is provided. A processing device of the environment recognition system receives a plurality of data points from at least one perception sensor. The processing device generates an environment map and detects a plurality of objects. Further, the processing device extracts a geometry and computes an expected shadow of each of the plurality of detected objects. The processing device detects one or more missing data points indicative of a casted shadow of the respective detected object. The processing device computes a geometry of the casted shadow and compares the casted shadow with the expected shadow of the respective detected object. The processing device determines whether the geometry of any of the plurality of detected objects has been misestimated based on the comparison of the casted shadow with the expected shadow of the respective detected object.
