Problems solved by technology

This method is time-consuming and labor-intensive, and it is easy to introduce artificial errors. The test of the photosensitive range of the sensor is not comprehensive enough. Artificially increasing the number of test points will further increase the difficulty and time of the test.

Embodiment Construction

[0025] The present invention will be further introduced in conjunction with the accompanying drawings and specific embodiments.

[0026] In one embodiment, the present invention proposes an automatic test device for brightness sensors for head-up displays, including a control system 1, a program-controlled uniform light source system 2 and a data acquisition card; The luminance sensor for the head-up display provides multiple groups of uniform light sources; the data acquisition card is used to collect the data fed back by the luminance sensor for the head-up display after receiving the uniform light source of the program-controlled uniform light source system 2, and transmits the feedback data to the control system 1; the control system 1 Used to control the program-controlled uniform light source system 2 to automatically output multiple groups of uniform light sources, synchronously receive multiple groups of feedback data from the data acquisition card, and fit multiple gro...

Abstract

The invention belongs to the technical field of head-up displays, and particularly relates to an automatic test device and method of a brightness sensor for a head-up display. The automatic test device comprises a control system, a program-controlled uniform light source system and a data acquisition card. The automatic test method comprises the steps of pre-setting a plurality of program-controlled uniform light source brightness on a control system with regard to test demands of the brightness sensor for the head-up display; and obtaining a plurality of uniform light source brightness valuesand an output signal of the brightness sensor, performing fitting after a plurality of coordinate points are built, and obtaining a brightness sensor characteristic curve. By the automatic test device and the automatic test method, the test efficiency and the test accuracy can be improved, the introduction of an artificial error is reduced, and the unattended operation requirement can be met.

Description

technical field [0001] The invention belongs to the technical field of head-up displays, and in particular relates to an automatic testing device and method for a brightness sensor for head-up displays. Background technique [0002] Head Up Display (HUD), referred to as HUD, is a flight aid commonly used in aircraft. Head-up means that the pilot can see the important information he needs without looking down. The head-up display first appeared on military aircraft, reducing the frequency of pilots needing to look down at the instruments, avoiding interruption of attention to the road ahead and loss of mastery of situation awareness (Situation Awareness). Because of the convenience of HUD and the ability to improve flight safety, civil aviation aircraft have also followed up with the installation, and now it has been gradually applied in the automotive field. [0003] As the main display in the cockpit of a fighter jet, whether the display brightness is appropriate directly...
