Vehicle-mounted three-dimensional all-round display method, computer readable storage medium and system

Abstract

The invention is applicable to the field of vehicle-mounted all-round view, and provides a vehicle-mounted three-dimensional all-round display method, a computer readable storage medium and a system.The method comprises the following steps: establishing a three-dimensional grid model, and amplifying the three-dimensional grid model to world coordinates; acquiring fisheye images around the vehiclebody collected by a camera, and performing distortion correction to obtain corrected images and coordinates of an imaging center; calculating to obtain a camera internal reference matrix according tothe coordinates of the imaging center; determining an external parameter matrix of each camera under a vehicle body coordinate system; determining a mapping relation between each point in the three-dimensional space and a planar pixel coordinate; rendering the content of the corrected image into a three-dimensional grid model to realize a three-dimensional panoramic all-round view; and displayingthe three-dimensional panoramic all-round view. The stereoscopic environment around the vehicle can be displayed on the display window more clearly, the view field range of the vehicle-mounted stereoscopic panoramic display system is widened, and the safety performance is improved.

Description

technical field [0001] The invention belongs to the field of vehicle-mounted surround view, and in particular relates to a vehicle-mounted three-dimensional panoramic display method, a computer-readable storage medium and a system. Background technique [0002] With the widespread use of automobiles and the further improvement of automobile intelligence, there are higher requirements for on-board image display. The increase in the number of cars and the restrictions on roads and parking spaces make driving and parking difficult for drivers. The auxiliary equipment mainly used during parking in the prior art includes reversing mirrors, reversing radars, rear-view fisheye lenses, etc. There is also a method of using multiple wide-angle cameras to obtain a bird's-eye view around the vehicle in a bird's-eye view. However, the main problem with these methods is that they cannot obtain complete images of the surrounding environment of the vehicle, and the displayed vehicle surrou...

Problems solved by technology

[0003] The object of the present invention is to provide a vehicle-mounted stereoscopic panoramic display method, computer-readable storage medium and system, aiming to solve the problem that the existing technology cannot completely acquire the surrounding environment image of the vehicle, and the surrounding range of the displayed vehicle is small. In addition, the bird's-eye view is only Displaying the ground conditions cannot better help the driver judge the surrounding environment, so the safety performance is still poor
