Real-time precise control technology of multidimensional and stereoscopic high-speed photogrammetry system

During the flight test, the high-speed photogrammetry stations are characterized by large number, scattered distribution, and separation of man and machine. In order to obtain the real-time measurement data of multiple targets in two separate areas of the take-off and landing section at the same time, a distributed high-speed photogrammetry network system was proposed based on the multicast concept, and an efficient uncorrelated signal high-speed camera trigger criterion algorithm was designed. Through the real-time acquisition of a variety of airborne and moving platform data, and through the image processing methods to complete the real-time precise intelligent control and the real-time unloading of massive data of multidimensional and stereoscopic high-speed photogrammetry system, the intelligent acquisition of test images from 8 different types of high-speed cameras was realized. The false trigger rate of the measurement system is reduced to 0.76%, which effectively improves the work efficiency and ensures the accuracy and efficiency of flight test data.
