Problems solved by technology

[0002] At present, the infrared sensor is mainly used to detect the movement of an object, and the object to be tested needs to carry the corresponding infrared sensing device. Since the infrared sensing device can only be effective within a certain distance range, beyond the effective range, it will not be able to sense and detect.
This greatly limits the scope of detection, and the cost of the detection device is relatively high

Embodiment Construction

[0012] See attached picture.

[0013] Start the matching thread, the thread steps include:

[0014] (1) Get the image captured by the current camera, and set the current captured image as the image;

[0015] (2) Judging whether the previous image is empty, if it is empty, then set the previous image as the current image, and skip to step (1); if it is not empty, then perform differential calculation on the two accompanying drawings, and set the previous image as For the current image, skip to step (3) if there is motion according to the difference result, and skip to step (1) if there is no motion;

[0016] (3) Synthesize the motion contour part calculated by the difference into the multimedia to be displayed through the virtual reality 3D synthesis method, and then skip to step (1).

[0017] The present invention is applied to products in science and technology exhibition halls, among which the "Spiderman" science and technology exhibit is applied to the method described in...

Abstract

The invention relates to an object motion detection method based on image motion. The method includes that: 1, the image shot by the current camera is taken, and the current shot image is set as the image; 2, whether the previous image is empty is judged, if yes, the previous image is set as the current image and the step 1 is returned, if not, difference operation is carried out on the two images and the previous image is set as the current image, and if the difference result shows that motion is detected, the step 3 is executed, if not, the step 1 is returned; 3, motion outline part calculated by difference is synthesized into multimedia to be exhibited by virtual reality 3D synthesis method to be displayed, and then the step 1 is executed. The invention provides a mobile object detection method with low detection cost and wide detection range.

Description

technical field [0001] The invention relates to a motion detection method, in particular to an object telemotion detection method for multimedia display. Background technique [0002] At present, the infrared sensor is mainly used to detect the movement of an object, and the object to be measured needs to carry the corresponding infrared sensing device. Since the infrared sensing device can only be effective within a certain distance, beyond the effective range, it will not be able to sense and detect. This greatly limits the detection range, and the cost of the detection device is relatively high. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a moving object detection method with low detection cost and wide detection range. [0004] The present invention is achieved through the following technical solutions: [0005] A method for detecting object motion based on image motion, starting a matching thread, and the th...
