Embodiment 1

[0040] Such as figure 1 A reminder method based on computer visual prevention vehicle collision, the reminder method of the vehicle collision includes the following steps:

[0041] S1: camera capture road vehicles and pedestrian data information;

[0042] S2: Road vehicle data information to the edge server;

[0043] S3: Edge Server For road vehicles and pedestrian data information;

[0044] S4: LED screen display displays real-time dynamic animation;

[0045] The specific configuration of the S3 contains the following steps:

[0046] S31: Based on the background of the OpenCV to perform moving object detection by the reduction algorithm, the dynamic foreground is separated from a static background, and the current picture and assumptions are the static background, and there is a significant change in the region, which can be considered. This area has moved objects;

[0047] S32: Store the coordinate position information of the detected moving object to construct a trace tracking...

Embodiment 2

[0052] Based on Example 1 figure 2 , image 3 , Figure 4 A reminder method based on computer visual prevention vehicle collision, the specific contiters of the S1 contain the following steps:

[0053] S11: The camera is targeted for the vehicle and pedestrians in the road area to obtain location information;

[0054] S12: The camera is estimated to give a motion direction information for vehicles and pedestrians in the road area;

[0055] Further, the specific configuration of the S4 contains the following steps:

[0056] S41: The displacement data format of the object speed and direction data generated in step S33 performs structural data output by the edge server to the LED screen display;

[0057] S42: Screen Display Synthesis The vehicle and personnel animation image that adapts to human eye, and presents the direction of motion and motion speed and early warning information of the vehicle on the LED screen that requires a reminder direction.

[0058] The camera is mounted t...

Abstract

The invention discloses a reminding method for preventing vehicle collision based on computer vision, and belongs to the technical field of computer vision equipment. A camera, an LED screen display,an embedded processor and a server are included. The method comprises the steps: acquiring the information of vehicles and pedestrians on a road through the camera, performing key data structuralization processing on the information of the vehicles and the pedestrians based on opencv, constructing trajectory tracking information of a moving object, analyzing the moving speed and direction of the object through trajectory tracking data, generating a displacement data format required by animation display through object speed and direction data, displaying the displacement data format through anLED screen display, synthesizing an animation of the cartoon trolley suitable for human eye observation, and presenting an animation schematic diagram of the movement direction and speed of vehicles and pedestrians to an LED screen needing direction reminding in real time; therefore, the problem of frequent occurrence of vehicle collision accidents in a parking lot due to poor reminding effect ofa traditional reminding method can be solved.

Description

Technical field [0001] The present invention relates to the technical field of computer vision, and more particularly to a reminder method for preventing vehicle collisions based on computer vision. Background technique [0002] Edge calculation is a technique attached to a physical machine. It allows local processing and analysis of data to collect data, not in the cloud or data center. The edge calculation cannot replace the cloud. It allows the machine to process new data separately when needed. In other words, the edges of the machine can learn and adjust according to their own experience, but independent of the larger network, the edge calculation solves the problem of network accessibility and delay. Under the development of edge computing, the device can be placed in a region where the network connection or does not exist. In addition, the edge calculation can also cancel some costs for the use and maintenance of cloud computing for data sharing. For computer vision softwa...
