HEIGHT INFORMATION RECONSTRUCTION SYSTEM AND HEIGHT INFORMATION RECONSTRUCTION METHOD

A height information reconstruction method suitable for a vehicle, includes: sensing multiple entities through a three-dimensional radar to generate a three-dimensional radar point cloud corresponding to the vehicle; sensing entities through an inertial measurement unit to generate inertial measurement data corresponding to the vehicle data; and executing through the processor: receiving the three-dimensional radar point cloud and the inertial measurement data, and calculating the radar displacement and radar velocity of the three-dimensional radar; calculating the radial velocity of each entity based on the radar speed; performing dynamic segmentation to extract a static entity in the entities based on the radar velocity and radial velocity; calculating the elevation angle of the static entity; performing temporal filtering to calculate the height value of the static entity based on the elevation angle and the radar displacement; and generating a height reconstruction radar point cloud based on the height value of the static entity.
