Example Embodiment

[0029] The present invention will now be further described in conjunction with the embodiments and drawings:

[0030] The invention relates to a target board device based on laser tracking technology and a target board positioning method. The target board device based on laser tracking technology includes a target board, a laser tracker target, a base, and an adjustment device. There is a reference mark on the target board, which is used to draw the calibration target line; the laser tracker target can receive and reflect the laser tracker signal, which is used to install on the target board and complete the spatial position measurement of the target board in the aircraft body coordinate system The adjustment device can adjust the base support to make the target plate complete three-axis translation and rotation adjustment; the base is used to place the target plate on the aircraft target calibration platform to keep the target calibration device stable. The target board positio...

Abstract

The invention belongs to a laser tracking technology-based target plate device and a target plate positioning method. The laser tracking technology-based target plate device includes a target plate, laser tracker targets, a base, and an adjustment device; the target plate is provided with datum identifiers through which target correction lines can be drawn; the laser tracker targets can receive and reflect laser tracker signals and are mounted on the target plate; the spatial position measurement of the target plate in an aircraft body coordinate system can be completed through the laser tracker targets; the bracket of the base can be adjusted through the adjustment device, so that the three-axial-direction translation and rotation adjustment of the target plate can be completed; and the target plate can be arranged on an aircraft target correction platform through the base, so that a target correction device can be kept stable. According to the target positioning method, the referencepoints of the target plate are spatially located in the aircraft body coordinate system; and spatial positional relations between target lines and the axes of an aircraft are calculated, so that theangle of the target plate in different axial directions can be adjusted, and therefore, the target plate maintains the same posture as the aircraft.

Description

technical field [0001] The invention belongs to an airborne equipment target board device and a target board positioning method, and relates to a target board device and a target board positioning method based on laser tracking technology. Background technique [0002] Airborne equipment target calibration refers to the combination of mechanical adjustment and electrical adjustment, so that the characters displayed on the airborne equipment are aligned with the external scene. When performing target calibration on head-up display (HUD), enhanced vision equipment (EVS), and other airborne equipment, the most critical step is to complete the positioning of the target board. At present, the accuracy of the traditional target plate positioning method is low. Due to the large measurement accuracy deviation, it cannot meet the product performance requirements. Some safety-critical symbols display large accuracy deviations, which may affect flight safety. In addition, the traditio...
