Pedestrian detection method and detection system thereof

Abstract

The invention provides a pedestrian detection method. The pedestrian detection method comprises the steps that (1) a laser range finder is installed, (2) laser cloud point data of the laser range finder are set by a laser scanner module, (3) a laser data preprocessing module is established, (4) obstacles in front of a vehicle are detected in real time through a pedestrian detection module, and (5) pedestrian targets are distinguished in real time through a pedestrian distinguishing module. The invention further provides a detection system for realizing the pedestrian detection method. The detection system for realizing the pedestrian detection method comprises a power supply, a DSP, a data circuit, a power circuit and the laser range finder, wherein the laser range finder is connected with a network interface of the DSP through the data circuit, the power supply supplies power to the laser range finder through the power circuit, and the laser scanner module, the laser data preprocessing module, the pedestrian detection module and the pedestrian distinguishing module are arranged inside the DSP. The pedestrian detection method and the detection system of the pedestrian detection method have the advantages that the detection speed is high, and the reliability and robustness are high.

Description

technical field [0001] The invention relates to an automobile active safety technology, in particular to a pedestrian detection method and a detection system thereof. Background technique [0002] At present, there are two ways of pedestrian detection technology, one is video-based pedestrian detection, and the other is laser-based pedestrian detection. Pedestrian detection technology based on video is easily affected by the external environment, such as illumination changes, fog, etc., and the detection robustness and real-time performance are poor. For the laser-based pedestrian detection technology, the real-time and accuracy of laser cloud point processing is not high, resulting in low reliability of the pedestrian detection system. Contents of the invention [0003] The primary purpose of the present invention is to overcome the shortcomings and deficiencies of the prior art, and provide a pedestrian detection method, which effectively improves the real-time performa...
