The invention discloses a vehicle anti-collision early warning system based on laser radar ranging. The vehicle anti-collision early warning system comprises 2n laser radar emitters and 2n optical lenses, wherein n is a natural number. Each laser radar emitter is paired with one optical lens to form a signal receiving and transmitting group. Each signal receiving and transmitting group is arranged along the central axis of a vehicle. An acute angle is formed between each optical lens and the vertical direction of the corresponding laser radar emitter. The laser radar emitters on one side of the central axis emit laser signals, and the laser signals are scattered after contacting with objects in places ahead and are received by the optical lenses at corresponding positions on the other side of the central axis. The vehicle anti-collision early warning system has the advantages that through intelligent anti-collision active early warning based on accurate laser radar ranging, users can get better experience effects; double-lens design is adopted, the lenses are treated specially in terms of optical design, and high-accuracy optical imaging and detecting and lens structure design applicable to complex in-vehicle environments can be guaranteed.
