Abstract

The invention provides a method and a device for determining a flying shooting trigger point. The method comprises the following steps: S1, obtaining a first image at a shooting point through static shooting; s2, intercepting a sub-image in the first image; s3, in the flying shooting process, sending a trigger signal to the camera at an undetermined shooting trigger point corresponding to the shooting point to obtain a second image; s4, performing template matching in the second image by using the sub-image as a template to obtain a target object in the second image; s5, obtaining coordinate information of the sub-image in the first image and coordinate information of the target object in the second image, and calculating a position deviation between the target object in the second image and the sub-image in the first image; and S6, adjusting the to-be-determined shooting trigger point according to the position deviation to obtain an actual shooting trigger point. According to the method, the deviation between the flying image and the actually required image can be conveniently, effectively and quantitatively determined, so that the shooting trigger point of the camera in the flying shooting process can be conveniently and accurately determined.

Description

technical field [0001] The present invention relates to the technical field of visual detection, and in particular to a method for determining a trigger point of a flying camera, a device for determining a trigger point of a flying camera, a computer device, and a non-transitory computer-readable storage medium. Background technique [0002] In the traditional process of using industrial cameras for visual inspection, the industrial cameras are fixed at the end of the robotic arm. When the workpiece to be inspected is transported to the shooting position, the robotic arm moves the camera to the shooting point of the workpiece, stops the motion and takes a static shot. Next, in the same way, the robotic arm carries the camera to take a static shot of the next point until all the positions to be shot are shot. In this process, the industrial camera needs to stop moving every time it reaches the shooting point, resulting in a long shooting cycle and low efficiency. [0003] In...
