Embodiment Construction

[0028] Such as figure 2 As shown, this embodiment provides a multi-optical-axis image deviation calibration method based on servo rotation. The calibration method uses the high-precision output of the turntable position to compensate, and realizes that the optical system does not need to be disassembled and re-adjusted. Calibration can be realized, and the calibration method first performs parallelism evaluation, and then performs specific calibration;

[0029] The complex photoelectric system has its own servo platform, which can be two-axis or three-axis, and finally can realize the free-space pointing change of the optical aiming axis system. Through the mutual relationship between the optical axes, the relative positional relationship between the two or three is determined, and this relationship is stable.

[0030] For the multi-optical system, due to the different working mechanisms of its multiple independent optical channels, each channel has its own working mode, and...

Abstract

The invention relates to a multi-optical-axis image deviation calibration method based on servo rotation. The calibration can be realized under the condition that a light path system is not disassembled and re-calibrated by utilizing a method for compensating position output high precision of a rotary table. The calibration method comprises the following steps: firstly, carrying out parallelism evaluation, and secondly, carrying out specific calibration. According to the multi-optical-axis image deviation calibration method based on servo rotation, the method that the optical axis deviation of the multi-optical-path system is compensated through high precision of position output of the rotary table is adopted, calibration can be achieved under the condition that the optical path system is not disassembled and adjusted again. Therefore, the product of which the precision cannot meet the use requirement of the system is changed to be usable, the external field maintainability of the product is improved, the product can be used as a conventional maintenance work which can be completed during regular inspection of the product, the maintainability of the product is greatly improved, and the time and the labor cost are saved.

Description

technical field [0001] The invention relates to a complex multi-optical path photoelectric calibration system, in particular to a multi-optical axis image deviation calibration method based on servo rotation. Background technique [0002] Servo deviation calibration is mainly used in photoelectric observation and sighting products on various large-scale platforms such as vehicle, ship and airborne. Eliminates bias and maintains system aiming accuracy. [0003] At present, in order to detect and identify targets under various climatic conditions, complex photoelectric sighting and sighting products are mostly equipped with visible light and infrared TV channels. At the same time, in order to obtain the distance information of the target, they are equipped with laser ranging or laser photometry systems. , the optical parallelism accuracy between these multi-optical channels is related to the exposed size, distance and other information of the target under consideration, and t...
