Laser bar code coding type precision target and test method thereof

The invention discloses a laser bar code coding type precision target and a test method thereof, and the target comprises a one-dimensional bar code and a laser scanner which are parallel to each other, an angle sensor, a signal collection and processing circuit, a data operation circuit, and an upper computer. The laser scanner is placed at the central position of the one-dimensional bar code and is used for emitting a fan-shaped laser beam, so that the fan-shaped laser beam irradiates the one-dimensional bar code to form a projectile detection view field and is used for obtaining projectile projection; the angle sensor and a light source of the laser scanner are located on the same straight line, and the angle sensor is used for outputting the real-time divergence angle value of current projectile incidence. According to the invention, a method combined with a bar code coding rule is adopted to replace an original light curtain trigger target, the structure is simpler, and the cost is very low; the FPGA is
