Reversing assisting method and system

Abstract

The invention discloses a reversing assisting method and a reversing assisting system, and the reversing assisting method comprises the following steps: obtaining an initial two-dimensional RGB imageand an initial three-dimensional depth image of an obstacle at the tail of a vehicle; fusing the depth information of each pixel point in the initial three-dimensional depth image with the two-dimensional feature information of each corresponding pixel point in the initial two-dimensional RGB image to generate a color reconstructed three-dimensional image containing the depth information of the initial three-dimensional depth image and the two-dimensional feature information of the initial two-dimensional RGB image; and displaying the color reconstructed three-dimensional image. According to the reversing assisting method and system, the driver can be helped to visually, comprehensively and clearly know the environment behind the vehicle by displaying the 3D scene information in real time,the reversing difficulty is reduced, the reversing safety is improved, and the reversing assisting method and system are suitable for various light and weather conditions.

Description

technical field [0001] The present application generally relates to the technical field of reversing images, and in particular relates to a reversing assistance method and a reversing assistance system. Background technique [0002] Reversing is an important skill in vehicle driving. Although the rearview mirror can assist in observing the surrounding environment, due to the existence of blind spots, the situation behind the vehicle cannot be fully known. With the help of the reversing auxiliary device, the situation behind the vehicle can be displayed to the audience in the form of visual images, etc. The driver, thereby effectively reducing the probability of reversing accidents. [0003] Existing reversing auxiliary devices mainly include a reversing image system and a reversing radar system. However, the existing car reversing imaging system can only display 2D image information of rear obstacles without distance information and depth information of objects. At the same...

Problems solved by technology

However, the existing car reversing imaging system can only display 2D image information of rear obstacles without distance information and depth information of objects. At the same time, it is also easily affected by light and environment, such as image resolution at night or in rainy days. poor rate

However, the existing reversing radar system can only inform the driver of the impending collision danger through an alarm. Although it can display the distance information of the object, it cannot display the image information of the object, so it cannot tell the driver which object in which direction. A collision is about to occur, and the driver needs to observe and judge through human eyes

[0004] At present, the 3D visual imaging scheme is gradually becoming the mainstream. However, the existing 3D visual imaging scheme has the defects of low pixels, insufficient image definition, and poor sensory perception, so it is difficult to apply to car reversing image imaging.
