Abstract

The invention relates to an image triggering device and a triggering method for a CCD precision target, which comprises a CCD camera, an optical lens, an integrated target frame, an image acquisitiondevice and an image triggering device. A pair of CCD cameras and optical lenses are respectively arranged at two base angles of the integrated target frame. The detection planes of the pair of CCD cameras and optical lens are parallel to each other. The CCD camera connects the image acquisition device and the image triggering device. The image acquisition device comprises a computer and an image acquisition card, and the image triggering device is connected with the image acquisition card. According to the image triggering device and the triggering method for the CCD precision target, which replaces the original light curtain triggering target of the CCD precision target, structure is simpler and cost is lower compared with the prior art. FPGA is adopted to process and analyze the image and send a triggering signal in real time, replacing the original delay triggering mode of the light curtain trigger, so that the triggering precision is higher and the instantaneity is stronger.

Description

technical field [0001] The invention relates to the technical field of gun and ammunition density testing, live ammunition shooting training and target position testing in sports shooting competitions, in particular to an image triggering device and a triggering method for a CCD precision target. Background technique [0002] Shooting range testing is an important link in the process of weapon production and development. It is mainly aimed at testing various performance parameters of weapons to determine whether various performance indicators and products of weapons are qualified or not. In the inspection of guns, cannons, bullets and propellants, the performance of the weapon aiming system, the performance of propellants, and the production quality of bullets and arrows are tested by measuring the shooting target density parameters of guns (cannons). At present, the development and production of new weapon systems put forward new requirements for the test of projectile vert...
