Abstract
The invention discloses a laser automatic shooting device, an impact point identification method, and an automatic impact point correction method. The laser automatic shooting device includes an automatic shooting control system and an automatic impact point identification system. The automatic shooting control system includes: a wireless module 1, a matrix The keyboard, the single-chip microcomputer connected with the matrix keyboard and controlled by it, the servo motor console connected with the single-chip microcomputer and controlled by it, and the laser gun located on the servo motor console, etc. The impact point recognition method is based on the gray value of the pixel, and adopts a non-adjacent recognition method between groups. In the method for automatically correcting the impact point, the servo motor console adjusts according to the difference between the impact point coordinates and the target coordinates, so as to correct the shooting deviation. The laser automatic shooting device has the advantages of low cost, low risk, strong objectivity and high precision. The method of non-adjacent recognition between groups based on pixel gray value is used to determine the point of impact. This method is more accurate and efficient, and its accuracy reaches 0.88%.
Description
technical field [0001] The invention relates to the field of laser shooting, in particular to a laser automatic shooting device, a method for recognizing a point of impact, and a method for automatically correcting the point of impact. Background technique [0002] Recognition of the point of impact, the existing technology uses a photodiode array to identify the point of impact. This technology is backward, and the recognition accuracy of the point of impact is not high, and the recognition is not stable enough. PSD (Position Sensitive Detector) is also used as a sensor to identify the impact point. PSD is a continuous analog spot position detection device. Its principle is to use the change of the surface impedance of the photodiode under the light to detect the spot position. This method is susceptible to ambient light, and its accuracy in identifying the point of impact is only 1%. At present, the laser shooting devices on the market cannot realize full automation, and ...
