Method and system for distinguishing moving object in mixed scene

Abstract

The invention provides a method for distinguishing a moving object in a mixed scene. The motion information of pedestrians and vehicles on a road is detected by using a Doppler microwave radar sensor,meanwhile, the magnetic field information of a road area is detected by using a geomagnetic sensor in combination with surrounding magnetic field change caused by vehicle movement, and therefore thepedestrians and the vehicles are effectively distinguished. A vehicle runs on a road, a magnetic field of a current area of the road is obviously changed, the geomagnetic sensor continuously monitorsthe change condition of the road magnetic field, a control module can timely and accurately judge whether the vehicle pass through the current area of the road or not by processing geomagnetic information collected by the geomagnetic sensor and carrying out algorithm analysis, and whether the pedestrians and the vehicles pass through the current area or not can be effectively judged in combinationwith a detection result of a microwave radar. According to the method, the problems of high misjudgment rate and the like when the Doppler microwave radar sensor is singly used to detect the pedestrians on the road are effectively solved, so that the accuracy of road pedestrian detection is improved, and the system is simpler and more efficient.

Description

technical field [0001] The invention belongs to the technical field of road pedestrian detection, and in particular relates to a method for distinguishing moving objects in mixed scenes. Background technique [0002] The ever-increasing number of cars has caused increasingly severe traffic problems. The operating efficiency of the traffic system has decreased, traffic safety is worrying, environmental pollution is serious, and resource consumption is intensified, which seriously hinders the sustained and rapid development of the economy and society. As the strategic direction of the future development of the automobile industry, unmanned driving technology can greatly improve the above problems. At the same time, smart roads, as a key part of building a collaborative integrated perception body for people, vehicles, roads, and networks, will capture energy and increase efficiency with smart driving technologies, strongly support the application of autonomous driving, and prom...

Problems solved by technology

[0008] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a method and system for distinguishing moving objects in a mixed scene, which can not only have high discrimination efficiency for pedestrians and vehicles, but also have strong applicability, and solve the existing problems. For the problems of high equipment cost and complex system in the detection method, the cost of detection can be reduced by using low-cost equipment, and through large-scale deployment of equipment, it can not only expand the detection area, but also improve the accuracy of detection
