High-speed image detection system for underground railways

The invention discloses a high-speed image detection system for an underground railway. The system is applied to the railway and is characterized by comprising a wheel, a light source and a high-speed camera which are sequentially arranged above the railway, wherein the light source is a laser light source, a photoelectric encoder is arranged in the wheel and connected with a signal processing circuit, the signal processing circuit is connected with the high-speed camera and connected with a PC (personal computer) connected with a GPS (global positioning system), and the irradiation angle of the high-speed camera corresponds to the light source. The high-speed image detection system for the underground railway can meet automatic underground tour-inspection requirement.
