The invention discloses a head-mounted miniature camera intelligent snapshot method for an experimental test, and the method comprises the following specific steps: firstly, estimating whether a camera moves or not and the change state of movement according to the size of the information amount of an inter-frame difference image when the camera moves through a camera movement condition sensing algorithm; then, through a character reading and scale region extraction algorithm based on inter-frame difference and optical flow tracking, on the basis of combining a difference operation result, optical flow information is fused, the motion reverse direction and speed of a target are further estimated, finally, through a snapshot signal adjustment and self-adaptive threshold technology, whether a camera has a snapshot condition or not is judged, and if yes, the target is shot. And if so, outputting a snapshot signal. According to the invention, moving target capture and key frame snapshot are realized.
Description
technical field [0001] The invention relates to the field of intelligent algorithms, in particular to an intelligent capture method for a head-mounted miniature camera used in experiments. Background technique [0002] At present, for the smart experimental equipment for junior and senior high school experimental exams, the cameras carried are distributed on the top, side, and front; when students are doing experimental operations, they need to read the display of some instruments and equipment on their own. A head-mounted portable camera is specially configured to accurately capture relevant indications and scales. [0003] In the specific capture process, the timing of the capture cannot be accurately grasped, resulting in the captured photos being easily blurred, not clear enough, or unable to capture key information, and there are certain defects. Contents of the invention [0004] The object of the present invention is to provide an intelligent capture method for a h...
