Embodiment Construction

[0066] figure 1 It is a schematic flowchart of a method for calibrating streaming media exterior rearview mirrors according to an embodiment of the present invention. like figure 1 As shown, in a specific embodiment, when the vehicle is in a stationary state, the method for calibrating the streaming media exterior mirror generally may include the following steps:

[0067] S10, receiving a trigger instruction for starting the calibration procedure;

[0068] S20, collecting image information around the vehicle through the panoramic collection module;

[0069] S30, identifying coordinate values ​​of preset key feature points in the image information;

[0070] S40. Comparing the coordinate values ​​of the preset key feature points with the original coordinate values ​​of the preset key feature points to calculate the change relationship of the coordinate system generated by the panoramic acquisition module relative to the original position;

[0071] S50, mapping the change rel...

Abstract

The invention provides a method and system for calibrating streaming media exterior rearview mirrors, and relates to the field of vehicles. The method for calibrating the exterior rearview mirror of the streaming media is to calculate the coordinate system change relationship of the streaming media acquisition module relative to the original position by mapping the coordinate system change relationship of the panoramic acquisition module to the coordinate system of the streaming media acquisition module, wherein, The panoramic acquisition module and the streaming media acquisition module are installed on the exterior rearview mirror on the same side of the vehicle, and then the coordinate system change relationship of the streaming media acquisition module is mapped to the display coordinate system of the streaming media display module to calculate the streaming media display module The display coordinate system of the display coordinate system is relative to the coordinate system change relationship generated by the original position, and finally the image display area of ​​the streaming media display module is readjusted according to the coordinate system change relationship of the display coordinate system of the streaming media display module. The invention can calibrate the field of view of the streaming media display module, saves development cost and is easy to operate.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a method and system for calibrating streaming media exterior rearview mirrors. Background technique [0002] Streaming media exterior mirror is an emerging automotive technology, which uses a camera installed on the exterior mirror of the car to collect images and then displays the image on the screen in the car to replace the traditional exterior mirror technology. Through this technology, the field of view displayed by the rearview mirror can be expanded, wind resistance can be reduced, and visibility in adverse environments such as rainy and snowy days and at night can be enhanced. [0003] The control of the field of view of the current streaming media exterior rearview mirror is mainly determined by the installation position of the camera and the field of view calibration parameters in the early stage. Once fixed, it cannot be changed. During the long-term use of the vehicle or afte...
