In order to achieve the consistency of the optical landing device and the midline television glide in the landing guidance system, ensuring system reliability and accuracy and enriching method for true value acquiring , carry out overall design of photoelectric calibration. This article presents a method to store the photoelectric calibration device in the ideal landing point for tracking the air target in real time. In the way, it can measure the spatial position information of the target relative to the ideal landing point and obtain the true value. Through the formula derivation, the article puts forward the index requirements of each component of the device, and introduces the overall design idea, the system structure and the main working principle of the photoelectric calibration system. The text elaborates the overall design and the system work process in detail. The analysis results show that the design can help the landing guidance system to work safely and reliably. It can meet the requirements of the calibration precision and provide some theoretical basis for the analysis of the true value measurement technology of the calibration system.
