Abstract
The invention provides a millimeter wave radar modeling-based method for object visibility determination, to solve the problem of object visibility determination based on virtual sensor modeling in intelligent vehicle simulation and testing, and improve the fidelity of sensor modeling while meeting simulation efficiency requirements. It includes the steps of target vehicle information detection to obtain target vehicle information; target vehicle reflection intensity simulation: for each target vehicle performing geometry culling on the target vehicle, discarding completely-invisible target vehicles, and calculating visible section information for each target vehicle that has a visible section, and reflection intensity calculation; target vehicle visibility determination: analyzing visibility of the target vehicle according to the target vehicle reflection intensity, and converting and outputting information of a visible object into an expression form of a real millimeter-wave radar sensing an object.
