Problems solved by technology

[0019] Existing technology 1 and prior art 2 can be spliced ​​through multi-view point conversion images to obtain the top view of the surround view and the top view schematic diagram of the vehicle, which are displayed on the left and right sides of the screen respectively. However, when the user uses the surround view system, It is not very clear which camera the content of the wide-angle lens large screen is obtained from, and which direction the scene is seen in, which is not conducive to the user's judgment. More intuitive and effective prompts are needed.
[0020] Existing technology 2 uses icons to indicate the current position on the screen, but the user needs to switch in sequence when switching cameras, that is, it can only be displayed in a fixed order, such as "front-left-right-back", if the current What is displayed is the picture of the front camera, but when the user wants to view the picture of the rear camera, he must always click the button to go through the left and right pictures to get the picture of the rear camera that the user wants, which adds a lot of unnecessary operations. User-friendly

Embodiment 1

[0044] Switching method 1 Implementation method: When the user touches or uses other input devices (such as a mouse, etc.) to press the wide-angle screen, record the touch position (x0, y0) and time t0. Once the dragging is started, the screen displacement d=x1-x0 and the dragging speed d / t0 are calculated according to the current touch position (x1, y1). If d<0, it means that the user drags the screen to the left, so that the wide-angle screen is divided into the left screen (the current camera wide-angle screen) and the right screen (the adjacent right camera wide-angle screen), and the size of each screen can be adjusted according to the amount of displacement. and drag speed to determine. Once the user stops touching, it means that the dragging is completed, and it is determined whether to perform screen switching according to the displacement of the last position and the dragging speed. If the displacement is less than the preset displacement threshold and the dragging s...

Embodiment 2

[0059] Implementation method: When dragging the right screen, the pointer rotates with the dragging speed to point to the switched direction or return to the current direction, so as to intuitively indicate the user's current observation direction. At the same time, there is a prompt icon arrow and corresponding text at the bottom of the single camera screen on the right. (Set the current screen as the right camera screen, drag to the right)

[0060] When directly clicking on the corresponding position of the composite image on the left to switch the camera, directly point the arrow to the corresponding direction.

Abstract

The invention relates to an around view system image display mode that can be understood by a driver easily. Functions of rapid screen switching and visual information prompting are realized by screen dragging and direct selection of an around-view picture, thereby helping a driver understand a spatial position of a picture that is currently observed. According to the invention, a problem of inconvenient operation by a driver during a camera switching process can be solved; and selectivity of the switching operation is ensured and the method well adapts to a using habit of the user. Meanwhile, visual and explicit prompting information can be provided for the driver, so that a position that is observed currently can be indicated. Moreover, the system operation is simplified; prompted information can catch attention easily; and problems of tedious procedures and vague information are solved.

Description

technical field [0001] The invention relates to a vehicle-mounted multi-eye camera surround-view system, in particular to a method for switching and displaying camera images of the vehicle-mounted multi-eye camera surround-view system. Background technique [0002] In today's society, cars have become an indispensable means of transportation. While people enjoy the convenience and speed brought by automobiles, automobile traffic accidents, environmental pollution caused by automobile exhaust emissions, and problems caused by traffic congestion have become increasingly serious global social problems. Therefore, there is a great market potential for reducing traffic accidents and improving automobile safety by using various advanced automobile safety technologies, equipment and concepts. [0003] After the 1990s, with the wide application of electronic technology, control technology, sensor technology and new materials in automobile products, automobile safety technology has...
