Problems solved by technology

In the prior art, the HUD image test is mostly the subjective judgment of human eyes, and there is no complete test system and test method for qualitative and quantitative testing of the HUD image. The existing HUD image test method also uses the CCD image sensor, luminance meter Equipment such as HUD images are tested for a single image content, a single brightness test, but cannot simultaneously test the HUD image range, image quality, size, color, and brightness. The test efficiency is low, the test accuracy is not high, and the HUD image cannot be realized. automatic testing

Embodiment Construction

[0029] The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings. The accompanying drawings are only for reference and description, and do not constitute a limitation to the protection scope of the present invention.

[0030] Such as figure 1 As shown, one aspect of the embodiment of the present invention provides a HUD image test system, including a programmable controller connected to the test host, a first movement device and a second movement device connected to the programmable controller, and the first The HUD host connected to the exercise device, and the CCD image collector connected to the second exercise device;

[0031] The test host is used to send a test command to the programmable controller;

[0032] The programmable controller is used to control the first movement device to drive the HUD host to enter the position to be measured. The HUD host to be tested is the installation position of the HUD ...

Abstract

The invention provides a HUD (Head Up Display) image testing system and method. The testing system comprises a programmable controller connected with a testing host, a first motion device and a second motion device connected with the programmable controller, a HUD host connected with the first motion device, and a CCD image gatherer connected with the second motion device. The testing host sends a testing command and an image acquisition control command to the programmable controller to make the programmable controller control the first motion device and the second motion device, so that the two motion devices drive the HUD host and the CCD image gatherer to reach a position that is identical to an actual vehicle HUD host installing position and also reach a position of the eyes when a driver views HUD images. The testing host conducts image visual field analysis, image quality analysis, image dimension analysis and image color and brightness analysis on the HUD images to complete an image test. In this way, range, image quality, dimension, color and brightness of the HUD images are automatically tested, the testing efficiency is high, and the testing precision is high.

Description

technical field [0001] The invention relates to the technical field of automobile head-up displays, in particular to a HUD image testing system and method. Background technique [0002] HUD (Head Up Display) is a head-up display, which is more and more widely used in automobiles. It avoids the need for the driver to look down to see the instrument information, making driving safer. In the prior art, the HUD image test is mostly the subjective judgment of human eyes, and there is no complete test system and test method for qualitative and quantitative testing of the HUD image. The existing HUD image test method also uses the CCD image sensor, luminance meter Equipment such as HUD images are tested for a single image content, a single brightness test, but cannot simultaneously test the HUD image range, image quality, size, color, and brightness. The test efficiency is low, the test accuracy is not high, and the HUD image cannot be realized. automatic testing. Contents of th...
