Embodiment Construction

[0026] The technical solution of the present invention will be described in detail below in conjunction with the drawings:

[0027] Such as figure 1 with 2 , An LDW calibration auxiliary device, including a shell cover 1 placed on the front windshield of a car. The shell cover 1 includes a left vertical plate 1-1 and a right vertical plate 1-3 which are vertically arranged. The bottoms of the left vertical plate 1-1 and the right vertical plate 1-3 are both provided with the front stopper of the automobile. The curved sides of the windshield are matched with the curved sides; the shell cover 1 also includes a horizontally arranged top plate 1-2, the left and right edges of the top plate 1-2 are respectively connected with the top edge of the left side vertical plate 1-1 and the right side vertical plate The top edges of 1-3 are connected; the shell cover 1 also includes a front connecting plate 1-4 located below the front edge of the top plate 1-2, and the left and right edges of...

Abstract

The invention discloses an LDW calibration auxiliary device. The device comprises a shell cover used for being placed on a front windshield of an automobile, and windows are formed in the bottom and the front side of the shell cover so that an LDW camera located below the shell cover can shoot a calibration plate located on the front side of the automobile. The LDW calibration auxiliary device further comprises a projection lamp arranged at the top of the shell cover and facing the calibration plate at front, and the front end of the projection lamp is located on the rear side of the front endof the shell cover. The shell cover mechanism arranged in the LDW calibration auxiliary device can be taken as the mounting base of the projection lamp and as the light shielding body of the LDW camera, and the projection lamp is just prevented from directly irradiating the camera at the top of the projection lamp, so that the calibration of the camera can be effectively prevented from being interfered by oblique radiation and reflected light in other directions, the camera can directly shoot the calibration plate through the windows at the bottom and the front part, good calibration conditions are provided for calibration work, the one-time success rate can be improved from 20% to 80% through experiments, and the effect is remarkable.

Description

Technical field [0001] The invention relates to an auxiliary device for calibrating an automobile lane departure system. Background technique [0002] LDW is an important part of the automotive ADAS system. LDW is the abbreviation of Lane Departure Warning, and it is the most commonly used function of driving assistance system ADAS. At present, most luxury cars are equipped with LDW, and domestically produced cars with independent brands have also begun to carry LDW. [0003] The core of LDW's physical structure is the front-facing monocular camera installed behind the front windshield. During the installation process of the production line, the following factors may cause the camera to deviate from the specified installation position: the manufacturing tolerance and installation tolerance of the bracket or windshield glass, etc. To ensure the functional accuracy of LDW, the camera must be rigorously calibrated to compensate for deviations. Static calibration will be used in ac...
