Abstract

The invention discloses a target object detecting method and device. The method and device can be applied to a millimeter wave radar model. Specifically, all target objects included in a simulation scene are determined at first; secondly, the target objects within the detection range of the millimeter wave radar model are screened out from all the target objects; clutters generated by a clutter model set by the millimeter wave radar model can also be obtained during screening; finally, the target object detected by the millimeter wave radar model is determined from the target objects within the detection range of the millimeter wave radar model and the clutters. By means of the method and device, the final target object is determined from all the target objects in the simulation scene andthe clutters generated by the clutter model so that the target objects in the simulation scene can be comprehensively detected by the millimeter wave radar model; moreover, the false alarming can be achieved, sensor data generated by the millimeter wave radar model is closer to that generated by a real millimeter wave radar, and the output fidelity of the millimeter wave radar model is improved.

Description

technical field [0001] The invention relates to the technical field of simulation testing, and more specifically, relates to a method and device for detecting a target object. Background technique [0002] Intelligent driving systems, such as ADAS (Advanced Driver Assistant Systems, advanced driver assistance systems) are important applications of artificial intelligence in the field of transportation. The intelligent driving system performs data fusion of the target signals in the real vehicle scene detected by millimeter-wave radar and other sensors (such as cameras and lidars) to form perception information about the surrounding environment of the vehicle. The intelligent driving system makes and executes driving decisions based on the perception information of the vehicle's surrounding environment, user travel needs, and high-precision maps. [0003] In the simulation test process of MIL (Model-in-the-loop) test and HIL (Hardware-in-the-loop) test of the intelligent dri...
