Embodiment Construction

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0033] The regulation GB15084-2014 has specific requirements for the field of view of the interior rearview mirror and exterior rearview mirror of the car: through the interior rearview mirror, the driver should be able to see a field of vision with a width of at least 20m on the horizontal road, and its central plane is the Longitudinal datum plane, extending from the driver's eye point 60m to the horizon; through the exterior rearview mirror, the driver can s...

Abstract

The invention relates to the technical field of automobile view checking, in particular to a vehicle rear view checking method. According to the vehicle rear view checking method provided by the invention, a plurality of visual boundary lines are obtained by moving a screen in a datum line, the visual boundary lines are connected and extended to form a view envelope, wherein the view envelope is a visual boundary of a real vehicle state, and the view envelope is compared with a standard view boundary required by GB15084 view laws and regulations, so that whether the visual fields of the inner rearview mirror and the outer rearview mirror of the vehicle meet the requirements can be judged. The visual field envelope can be extended and generated only by obtaining the visual boundaries of the screen at different positions, and the small-distance movement of the screen can meet the requirements, so that the occupied area of a detection site is reduced, and the checking is more convenient.

Description

technical field [0001] The present invention relates to the technical field of vehicle field of vision calibration, in particular to a vehicle rear vision calibration method. Background technique [0002] When the car is driving, the driver mainly observes the situation behind the car through the rearview mirror. Therefore, the rearview mirror plays a very important role in the safety of the car. Various countries and regions have formulated regulations on the field of view of the rearview mirror. Or standard, to ensure that the driver has good rear vision. Therefore, in order to meet the regulations or standards of various countries or regions on the field of view of rearview mirrors, automobile manufacturers need to check the rearview mirrors of automobiles. However, traditional measurement methods require a large space and are inconvenient to measure. Contents of the invention [0003] The application provides a method for checking the rear view of a vehicle, which sol...
