Traditional photoelectric detection systems are designed for a single special task and cannot meet the needs of detection and identification for different tasks. Therefore, a concept of adaptive intelligent photoelectric detection system based on measurement data is proposed. The method of self-adaptively correcting the system parameters by onboard autonomous data processing and analysis of different task requirements is described. This paper introduces the establishment of the system parameter case library and the method of determining the scenes and targets and adaptively selecting the operating wavelength band using Fourier spectroscopy. For surface targets and point target detection, the sharpness evaluation function and the integrated signal-to-noise ratio are respectively used as the reference function, which provide feedback to adaptively adjust parameters such as aperture, gain, focal length and integration time, to achieve the best imaging mode and thus meet the requirements for detection and identification of multiple types of targets.
