Abstract

The invention provides a vehicle-mounted W-shaped HUD visual range whole vehicle test method. The method comprises the following steps of S1, test equipment connection and fixation, an HUD head-up display is arranged on a movable bracket of a test bed, a bottom end of a manipulator is fixed on a main driving position of the test bed, and a visual camera is arranged at a front arm end of the manipulator; S2, line connection, the computer is connected with a controller of the mechanical arm through a control line, the controller is used for driving the mechanical arm to move, the visual camera is connected with the computer through a USB data line, and the visual camera transmits shot images to the computer through network communication; S3, visual camera position calibration, the computer adjusts the angle of the visual camera by controlling the manipulator, and the imaging center of the HUD head-up display is located in the center of the visual field of the visual camera; and S4, imaging calculation and analysis of the HUD head-up display; According to the method, HUD imaging can be collected, calculated and analyzed in a short time, and the visual range of the HUD can be accurately measured.

Description

technical field [0001] The invention belongs to the field of automobiles, and in particular relates to a vehicle testing method for a vehicle-mounted W-shaped HUD with a visual range. Background technique [0002] With the vigorous development of the smart car industry, emerging human-computer interaction technologies such as HUD head-up displays are widely used in the automotive industry. HUD head-up displays can project vehicle speed, speed, water temperature and other vehicle condition information to the windshield. The quality of HUD head-up display products varies, and the rationality of the HUD head-up display viewing range has an important impact on the readability of the HUD head-up display, which in turn affects the driving safety performance. At present, there are no relevant test evaluation standards and testing technologies. The evaluation mainly relies on subjective evaluation and simple equipment evaluation with low precision. There is no professional and perfe...
