Pedestrian detection method, device, computer equipment and storage medium

Abstract

The invention relates to a pedestrian detection method and device, computer equipment and a storage medium. The method comprises the steps that sensing data is acquired; the sensing data is preprocessed to obtain preprocessed data; whether or not a pedestrian passes through is judged according to the preprocessed data; if yes, early warning information is generated; and the early warning information is broadcast for early warning. According to the method, the sensing data detected by multiple microwave sensors and geomagnetic sensors is acquired, the cost can be reduced by adopting the low-power consumption sensors, the sensing data is preprocessed to obtain the smooth preprocessed data, and then the high reliability of detection is guaranteed; and then whether or not the pedestrian passesthrough is judged according to the preprocessed data, the early warning information is generated, broadcast and sent to all vehicle-mounted terminal equipment in the detection range on the conditionthat the pedestrian passes through, therefore, enough emergency situation reaction time is provided for drivers, and then the traffic accident occurrence possibility is decreased.

Description

technical field [0001] The present invention relates to a pedestrian detection method, more specifically to a pedestrian detection method, device, computer equipment and storage medium. Background technique [0002] With the development of the economy and the automobile industry, the number of automobiles has shown a sharp increase, which has led to a series of problems such as low traffic safety factor, low traffic operation efficiency, and increased resource consumption, which seriously hinders the sustained and rapid development of the social economy. In order to solve the above problems, countries around the world have successively proposed the idea of ​​building smart roads. As one of the most important parts of smart roads, the pedestrian detection system has always been regarded as an important means to improve road safety. The pedestrian detection system encapsulates all functional modules in a device similar to road studs through a highly integrated design. These de...

Problems solved by technology

[0003] Most of the existing pedestrian detection systems use vehicle-mounted equipment to detect pedestrians, such as cameras and laser radars. In terms of road facilities, most of them use traffic detection equipment for regional detection, such as using infrared radiation devices to remind pedestrians crossing the road , the detection function is single, and the reliability is not high. Due to the limited range of single-vehicle perception and the single local detection function, strict reliability cannot be guaranteed in more complex and changeable traffic scenes, and misjudgments and missed judgments are easily generated, which affects detection efficiency.

At the same time, due to the weak anti-interference ability of infrared radiation, cameras and other equipment, the detection efficiency will be greatly reduced in bad weather conditions such as rainy days and foggy days.

In addition, considering that the existing detection equipment is expensive and not suitable for large-scale deployment, it is mostly installed in densely populated areas, which greatly reduces the applicability and penetration rate of such equipment. It can be seen that the existing technology is difficult Meet the reliability and safety requirements in scenarios with complex and changing traffic conditions
