Method and device for realizing view follow-up in panoramic look-around system and medium

Abstract

The invention provides a method and a device for realizing view follow-up in a panoramic look-around system and a medium, which can achieve the effect that a 3D view rotates along with a real-time steering angle of a steering wheel, assist a user to observe whether an obstacle exists around a vehicle or not, calibrate a camera of the panoramic look-around system and obtain internal and external parameters of the camera. A 3D projection model is constructed, world coordinates of the model points for constructing the 3D projection model under a world coordinate system are obtained; an image shotby a camera of the panoramic look-around system is collected, world coordinates of an original image of the shot image are calculated according to the obtained internal and external parameters of thecamera of the panoramic look-around system, the image shot by the camera of the panoramic look-around system is pasted to the 3D projection model by using a texture map, and splicing is performed toobtain a 3D panoramic image; and a corresponding 3D view is obtained according to the selected visual angle, a visual angle parameter is set, and a relationship between the rotation angle of the steering wheel and the visual angle parameter is set, so that the 3D view under the selected visual angle can rotate according to the rotation of the steering wheel.

Description

technical field [0001] The invention relates to the field of driving assistance and image processing, in particular to a method, device and medium for realizing view follow-up in a panoramic surround view system. Background technique [0002] With the vigorous development of China's economy and the improvement of people's living standards, cars have entered thousands of households like mobile phones a few years ago. Although the number of domestic traffic accidents has decreased year by year in recent years, the continuous increase in the number of cars has also brought great challenges to the guarantee of traffic safety. In addition to the improvement of traffic laws and the improvement of people's traffic safety awareness, various driving assistance systems have also reduced the probability of traffic accidents to a certain extent. [0003] Among them, the panoramic surround view system is one of the most widely used assisted driving technologies, which allows the driver ...

AI Technical Summary

Problems solved by technology

The existing panoramic view system has a relatively single function, which can only simply reflect the scene around the car at the current moment, and cannot support the panorama view of the scene around the car to select the viewing angle and display the 3D view under a specific viewing angle. Adjusting the angle of the 3D view synchronously under the current driving conditions is not conducive to the driver's observation of some detailed environmental conditions, and it is difficult to observe whether there are obstacles around the vehicle; at the same time, it is impossible to predict the area that the car will pass when it is running according to the current driving conditions.
