Embodiment Construction

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0035] The main idea of ​​the present invention is: put the operation of the complex dynamic vehicle auxiliary line algorithm in the application layer, generate the coordinate value sets of several groups of track points used to draw the vehicle auxiliary line, and store the coordinate value sets in the pre-divided In the good flash memory partition; during the loading process of the operating system kernel, the driver modules necessary for image acquisition and display such as camera, framebuffer, and display are loaded first, and the coordinate values ​​​​saved in the pre-divided flash memory partition are loaded. After that, the camera can be started immediately and the vehicle auxiliary line can be drawn to display the reversing image with dynamic vehicle auxiliary line, so that the image display can be advanced as soon as possible before t...

Abstract

The invention provides a method for rapidly displaying a rear view camera for supporting dynamic vehicle auxiliary lines, and belongs to methods for rapidly displaying vehicle images. The method comprises the following steps that a kernel module used for image collection and display is loaded; and tracing point coordinate values which are used for drawing the dynamic vehicle auxiliary lines and stored in a fixed storage area in a flash memory are loaded into the flash memory, and then the calibration step and the display step of loading and application layers of other modules of a kernel are executed at the same time. The method has the beneficial effects that a special flash memory partition is created, data are written in through calibration operation of the application layers, the data are read by the kernel to draw a trace line, and therefore the complex dynamic vehicle auxiliary lines are successfully applied to the kernel layer; and the drive module necessary for image collection and display and the coordinate values used for drawing the tracing points of the vehicle auxiliary lines are preferentially loaded, therefore, the rear view camera with the dynamic vehicle auxiliary lines can be displayed in the initial loading stage of the kernel, response time is greatly shortened, and more visual and accurate driving assistance can be given to a user.

Description

technical field [0001] The invention relates to a method for quickly displaying images of vehicles and machines, in particular to a method for rapidly displaying reversing images supporting dynamic vehicle auxiliary lines. Background technique [0002] With the rapid development of embedded technology, in-vehicle infotainment systems are being used more and more in the field of automotive electronics, which greatly improves the user experience; The technology is favored, which brings great convenience to drivers and avoids unnecessary collisions. Therefore, in-car products with reversing images will become standard equipment for cars. [0003] At present, most of the car products with reversing images on the market have certain defects: [0004] (1) The vehicle auxiliary line is non-dynamic. The auxiliary lines of most reversing images are static and cannot display the vehicle’s reversing trajectory. Users still need to cooperate with the rearview mirror to reversing. If...
