A method and device for combining and displaying vehicle images and road surface images

Abstract

The invention discloses a method and a device for combined display of a vehicle image and a road image. The method comprises the following steps: when taking the road image through a camera device mounted on a vehicle, acquiring the vehicle image corresponding to the time that each frame of the road image is taken; combining each frame of the road image with the vehicle image acquired at the corresponding taking moment so as to form a frame of vehicle-road image, and displaying the vehicle-road image in a vehicle display area, wherein the vehicle image in the vehicle-road image can be displayed in a perspective manner, and the perspective manner is that the road image covered by the vehicle image can be seen through the vehicle image; continuously displaying a plurality frames of the vehicle-road images in the vehicle display area. By adoption of the method and the device, the problem that a driver cannot accurately judge the relative position of a wheel and a barrier or a mountainous road edge when backing a vehicle or driving on a mountainous road can be solved.

Description

technical field [0001] The present invention relates to the field of vehicle image display, in particular to a method and device for combining and displaying vehicle images and road surface images. Background technique [0002] When the car is reversing, it is necessary to provide the driver with a reversing assistance function to ensure driving safety. In the prior art, two methods are commonly used to provide the reversing assistance function. The first method is to install a camera device at the rear of the car, and the image in a certain area behind the car captured by the camera device is displayed in real time in the image display area of ​​the car. The second way is to use ultrasound to detect the distance between the car and the rear obstacle to remind the driver. The defect of the first method is that the driver can only see the 2D image in a certain area behind the car through the image, and cannot accurately judge the exact relative position relationship between ...

Problems solved by technology

[0005] Based on the above problems, the present invention proposes a method for combining the vehicle image and the road surface image. By combining the road surface image and the vehicle image, the vehicle road surface image is displayed in the display area of ​​the vehicle, and the vehicle image can be displayed in the vehicle road surface image. The perspective display method solves the problem that the driver cannot accurately judge the relative positional relationship between the wheel and the obstacle when reversing, and also solves the problem that the driver cannot accurately judge the relative positional relationship between the wheel and the edge of the mountain road when driving on a mountain road
