A moving object detection method based on 360-degree panorama

Abstract

The invention provides a moving object detection method based on a 360-degree panorama, which includes: four-channel video image data collection around the vehicle without blind spots; four-channel video image processing around the vehicle and panorama splicing to form a 360-degree panorama overhead view; according to the 360-degree panorama In the top view, a cascaded global-local spatio-temporal saliency model is used to detect moving objects around the vehicle; the boundary line around the vehicle is generated according to the dynamic data collected in real time; the distance between the moving object and the boundary line of the vehicle is measured The relative distance generates an alarm signal according to the alarm rules. The invention adopts machine vision technology to analyze the running state and speed of the vehicle, detect the moving objects around the vehicle according to the video sequence formed by the 360-degree top view, and combine the driving state and speed of the vehicle to give a timely and accurate alarm signal , to remind the driver to adjust the driving state in time and drive carefully, thereby reducing or avoiding traffic accidents.

Description

technical field [0001] The invention relates to the field of automotive electronic information technology processing, in particular to a moving object detection method based on a 360-degree panorama. Background technique [0002] As the potential of my country's automobile market continues to be released, the number of automobiles continues to grow rapidly, and a large number of traffic accidents follow. Due to factors such as lack of concentration, especially with the popularity of smart phones in recent years, some drivers answering calls and playing with mobile phones while driving at low speeds have also caused certain traffic accidents. In addition, the bloodshed caused by reversing has also attracted more and more attention. In the accidents caused by reversing, most of them are caused by the blind spots of vehicles. [0003] In order to effectively reduce or avoid traffic accidents caused by factors such as driver inattention or vehicle blind spots, major manufacturer...
