The multi-line laser intersection encoding type target position testing device comprises a testing device main body, an intelligent signal collection instrument and an upper computer. The testing device main body is arranged in the position away from a certain distance in the extension direction of gun shooting and connected with the intelligent signal collection instrument. The intelligent signal collection instrument is connected with the upper computer. The testing device main body is perpendicular to the horizontal plane. A photoelectric detection unit and a laser emitting unit are arranged on the testing device main body. The testing device main body is configured to be used for transmitting a signal of the photoelectric detection unit to the intelligent signal collection instrument, then transmitting the processed signal to the upper computer and finally obtaining target projectile impact coordinates after analyzing and processing are conducted. According to the multi-line laser intersection vertical target testing device and method, the target projectile impact precise position coordinates can be obtained, the testing system precision is significantly improved; and meanwhile, the interference of stray light also can be effectively eliminated.

Description

technical field [0001] The invention relates to the field of photoelectric testing of shooting ranges, in particular to a multi-line laser intersection encoding type target position testing device and testing method. Background technique [0002] In the field of shooting range testing, the flight dynamic parameters of projectile targets restrict the development of weapons, such as flight speed, flight azimuth, and vertical target coordinates. The change of these parameters will have a great impact on the launch performance and damage performance of the weapon, so the acquisition of the target's flight parameters is an important technical index in the range test. At present, the test equipment mainly includes target plate method measurement, multi-light curtain intersection measurement method, and double CCD intersection measurement method. The target board method adopts contact measurement. Materials such as wood board, cardboard or textile cloth are erected on a surface pe...

Problems solved by technology

The six-light-curtain intersection measuring system is based on the original four-light-curtain intersection-standing target. By adding two light curtains, the speed and space vector angle of projectiles obliquely entering the light curtain are realized. This system successfully solves the four-light-curtain intersection and vertical target. The target test device is inaccurate in measuring the target point and velocity of projectiles obliquely incident on the light curtain, but the six light curtain intersection test device still has problems such as complex system structure and insufficient detection sensitivity.

The drive and data acquisition circuit of the CCD device needs the sky curtain target or the muzzle signal as the trigger source, which affects the reliability of the system work, and when the dual-CCD intersecting vertical target measurement system is used for outdoor small-caliber projectile measurement, there is a problem of low detection sensitivity. shortcoming
