Laser spot center detection method and device, computer equipment and storage medium

Abstract

The invention discloses a laser spot center detection method and a device, computer equipment and a storage medium, and belongs to the technical field of computers. The detection method comprises thefollowing steps: firstly, acquiring a laser spot original image to be subjected to center detection, and carrying out enhancement processing on the laser spot original image to generate an enhanced laser spot image; then, converting the laser spot image after enhancement processing into a laser spot image histogram, removing pixel values smaller than a threshold value in the laser spot image histogram, and converting to generate a laser spot image after filtering processing; then, carrying out edge detection on the filtered laser spot image to obtain a contour feature image of the laser spot;and finally, determining the center of the laser spot in the laser spot original image according to the contour feature image of the laser spot. Through the detection method, the detection efficiencyof the laser spot center can be greatly improved, the labor cost is greatly reduced, and the detection precision requirement can be ensured.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a laser spot center detection method, device, computer equipment and storage medium. Background technique [0002] Detecting the center of the laser spot is one of the important means for evaluating the hit accuracy of the laser transmitter. [0003] However, the traditional laser spot center detection method is directly observed by human eyes. Due to the short duration of laser emission, it is difficult for human eyes to capture the position of the center of the laser spot. In addition, although in the prior art, the image of the light spot is taken by the camera to judge the position of the center of the laser spot, but because the center of the light spot image taken by the camera is relatively divergent, the brightness difference is large, so the detection efficiency is low and the detection accuracy is low.

[0003] However, the traditional laser spot center detection method makes it directly observed by human eyes. Due to the short duration of laser emission, it is difficult for human eyes to capture the position of the center of the laser spot.

In addition, although in the prior art, the image of the light spot is taken by the camera to judge the position of the center of the laser spot, but because the center of the light spot image taken by the camera is relatively divergent, the brightness difference is large, so the detection efficiency is low and the detection accuracy is low.
