The invention discloses an application of stroboscopic target recognition on a lunar surface gravity simulation system. The stroboscopic frequency of five basic feature points on a stereoscopic target of the lunar surface gravity simulation system is set to be a fixed frequency, and frequency values of other six standby feature points are set to be different from the fixed frequency. Compared with the prior art, an infrared LED which can strobe according to the set frequency is adopted, a light-emitting spectra band and a light-emitting frequency are limited in the image recognition process, light sources which meet the two conditions can get access to an image recognition program, and system work reliability is greatly improved.
