360-degree panoramic reversing image generation method based on single camera

Abstract

The invention discloses a method for generating a 360-degree panoramic reversing image based on a single camera. A single camera is installed at the rear of the car to receive the real-time picture behind the car; the real-time speed of the car and the steering wheel rotation angle information obtained by using the CAN bus protocol of the car are calculated. The rotation center and the rotation angle of the image at the previous moment relative to the image at the current moment; the image at the previous moment is rotated and spliced ​​with the image at the current moment to generate a 360-degree panoramic reversing image. During the process of reversing the car, the generated 360-degree panoramic reversing image is continuously displayed on the display screen, which can feed back the static environment during the reversing process of the car and the dynamic information behind the car captured in real time to the driver, helping the driver during the reversing process Effectively avoid obstacles that appear in the blind area of ​​vision at different times, and assist the driver to reverse safely. On the basis of effectively saving costs, the invention can not only observe the real-time picture information behind the vehicle, but also observe the static obstacle information in the blind area on the side of the vehicle.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for generating a 360-degree panoramic reversing image based on a single camera. Background technique [0002] With the improvement of the consumption ability of Chinese residents and the popularization of cars, more and more people choose to buy cars as a means of transportation. Due to the unavoidable problem of blind spots in traditional cars, and many parking spaces are getting narrower and narrower, parking has become the most annoying thing for many "car owners", especially for novice drivers. If the operation is not done properly, it is easy to fail to reverse into the parking space during the process of reversing, or to collide with obstacles, and more seriously, it is possible to injure a child in the blind spot of vision. Therefore, a technology that can allow the driver to observe the blind area of ​​the field of view in real time during the reversing...

AI Technical Summary

Problems solved by technology

[0004] At present, the three common systems for assisting drivers in parking on the market all have certain technical shortcomings: 1. The driver cannot intuitively know the type and size of rear obstacles only through ultrasonic sensors; 2. Install a The camera solution can only allow the driver to see the real-time picture behind the car, and the driver cannot know the position of the static obstacle in the blind spot on the side and rear of the car and the relative position of the car in the entire reversing environment; Although the solution of a wide-angle camera can effectively solve the above problems, compared with the solution of a single camera, its use cost is higher and memory resource consumption is large.
