Abstract

The embodiment of the invention discloses a virtual image information measurement method and system based on a head-up display system. The method comprises the following steps: when the image of the virtual image of the content displayed on the screen captured by the camera is clearest, the identification content on the measurement contrast board is captured by the camera, and the image of the identification content is obtained; wherein the screen performs 2D display on the display content; when the image of the identification content captured by the camera is clearest, a distance from the camera to the measurement contrast plate is taken as a virtual image distance of the display content. The embodiment of the invention can objectively and accurately measure the virtual image information,avoids human error on subjective factors caused by human measurement, has good repeatability of measurement, and improves the reliability of measurement data of the virtual image information.

Description

technical field [0001] The embodiments of the present invention relate to the field of measurement, and in particular to a method and system for measuring virtual image information based on a head-up display system. Background technique [0002] With the development of science and technology, the emergence of Head Up Display (HUD) system can display the information and signs around the vehicle driven by the driver in front of the driver, which greatly improves the driving experience of the driver. [0003] In the existing HUD system, the eyes see the virtual image in front of the windshield, and the distance, distortion and magnification index of the virtual image are the key factors affecting the effect of the HUD system. Therefore, the measurement of image distance, distortion measurement and magnification measurement is a necessary and important work. The measurement of the above parameters is usually to describe the virtual image distance, distortion and magnification t...
