According to the characteristics of micro electro-optical pod, using the Qt framework and C/C++ language to design and implement the display and control software of a certain type of airborne micro-photoelectric pod; the software is designed in a multi-threaded way to realize the serial ports based on the QtSerialPort module. Data transmission and reception; video stream reception and decoding based on the open source codec library FFmpeg; multiple tasks such as target detection and recognition based on the YOLOv3 model detection algorithm; each module uses threads independently, and uses Qt's signal slot mechanism to transmit messages to make the software The program level is clear, the readability is strong, and it is conducive to the modification and addition of subsequent functions; the YOLOv3 algorithm is used for target recognition in the ground high-performance equipment, and the detection speed and recognition accuracy are significantly improved when the video delay meets the requirements; finally , after many experiments, the reliability and effectiveness of the display and control software have been verified.
