Camera hdr image effect switch control method, device, rearview mirror, vehicle and storage medium

Abstract

The invention discloses a switch control method and device for the HDR image effect of a camera, a vehicle-mounted electronic rearview mirror system, a vehicle and a storage medium. Wherein the camera is arranged on the outside of the vehicle to collect images of the external environment of the vehicle. The method includes: obtaining a real-time video of the external environment of the vehicle, and extracting each frame of image in the real-time video; obtaining the target in the blind spot of the vehicle according to each frame of image The moving speed of the object, and obtain the real-time speed of the vehicle; according to each frame of image, the moving speed of the target object in the blind spot of the vehicle, and the real-time speed of the vehicle, detect whether it is necessary to control the switch state of the camera HDR image effect. By controlling the on / off status of the HDR image effect of the camera, this method can realize clear image output for the driver at night, in direct sunlight, and in rainy and foggy days. At the same time, it can also ensure that HDR is automatically switched when driving at high speed to improve driving safety and reduce a lot of traffic. ACCIDENT.

Description

technical field [0001] The invention relates to the field of vehicle control, in particular to a method and device for switching control of HDR image effects of a camera, a vehicle-mounted electronic rearview mirror system, a vehicle, and a computer-readable storage medium. Background technique [0002] With the development of automotive electronic product technology, users have higher and higher additional requirements for automotive electronic products. For example, the application of vehicle-mounted electronic rearview mirrors is increasingly being put on the agenda, but conventional vehicle-mounted electronic rearview mirrors usually use a camera with HDR (High Dynamic Range Imaging, high dynamic range imaging) technology installed on the rearview mirror of the vehicle. mirror, and display the high dynamic range images collected by the camera on the display device in the vehicle electronic rearview mirror system, so that the driver can understand the environment behind t...

Problems solved by technology

[0003] But the problem that exists at present is: the existing conventional vehicle-mounted electronic rearview mirror only adopts HDR technology to improve the visual effect of the image through the camera, and in the process of high-speed driving, if adopting HDR, one frame of image will be synthesized from multiple frames and If the synthesized image is displayed on the display device in the vehicle electronic rearview mirror system, the frame rate of the camera will be affected due to the high speed of the vehicle at high speed, so the image to be seen may not be displayed on the display device , thus having a certain impact on driving safety
