Abstract

The invention provides a head-up display combination instrument assembly precision rapid calibration terminal. The terminal comprises a combination instrument positioning device, a standard graph generation unit, a graph projection unit, a data processing and transmission unit and an image acquisition unit. According to the head-up display combination instrument assembly precision rapid calibration terminal provided by the invention, automatic acquisition and calculation of projection pictures are completed by adopting an image acquisition and image processing technology, the acquisition efficiency, precision and calculation accuracy are improved, and human errors are prevented from being introduced; the position of the combination instrument is automatically controlled by adopting standard combination instrument position parameters, and installation errors are prevented from being introduced.

Description

technical field [0001] The invention belongs to the field of calibration of airborne avionics equipment, and in particular relates to a quick calibration terminal and a calibration method for the accuracy of components of a head-up display combination instrument. Background technique [0002] The precision calibration of the head-up display combination instrument component refers to electronically adjusting the position of the head-up display combination instrument component to display the projection screen of the head-up display projection device within the tolerance range of the theoretical ideal position. At present, the accuracy of the projection accuracy calibration method of the traditional head-up display combination instrument components is low, resulting in large deviations in measurement accuracy and unable to meet product performance requirements. Some safety-critical symbols display large deviations in accuracy, which in turn affects flight safety. In addition, t...
