Abstract

The invention discloses a standard comprehensive target board for rapid self-calibration of a photoelectric system and a measurement method for the photoelectric system. The standard comprehensive target board is mainly technically characterized by comprising a base plate, a pattern, a substrate and a pressure ring. The base plate, the pattern, the substrate and the pressure ring are sequentially compressed and packaged in a housing. The pattern is formed by filling triangular through hole arrays which are etched a metal film and which are filled with micro-nano display powder. The standard comprehensive target board is placed in an optical system far field (a focal plane or far distance of a collimator) of the photoelectric system to be measured, the photoelectric system is aligned with the standard comprehensive target board to emit laser, the pattern of the standard comprehensive target board reflects a laser spot image and instantly radiate a visible-light and infrared laser spot image, the photoelectric system to be measured receives and stores the digital image, geometric center and linear length of a through hole and triangle complementary array in the digital image are calculated, and the geometric center and linear length are compared with theoretical values so that digital image correction function, resolution, radiation precision, tracking angular speed and tracking precision parameters of the photoelectric system are obtained.
