CN101795348A - Object motion detection method based on image motion - Google Patents

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

A kind of method based on the motion of image motion inspected object

Technical field

The present invention relates to a kind of method for testing motion, be specifically related to a kind of object telemechanical detection method that is used for multimedia show.

Background technology

Detect the main employing of object motion infrared sensor at present, and need measured object also will carry corresponding infrared inductor,, can't respond to detection because infrared inductor can only in the scope of certain distance effectively exceed this effective range.Limited to the scope that detects so greatly, and this checkout gear cost is higher.

Summary of the invention

The present invention is directed to the deficiencies in the prior art, provide a kind of detection cost low, the moving object detection method that detection range is wide.

The present invention is achieved by the following technical solutions:

A kind of method based on the motion of image motion inspected object starts the coupling thread, and the thread step comprises:

(1) get the image that current camera photographs, putting the current shooting image is this image;

(2) whether piece image is empty in the judgement, is sky, and then putting piece image is present image, jumps to step (1); Then two accompanying drawings are not carried out Difference Calculation for sky, putting piece image is present image, has motion then to jump to step (3) according to difference result, does not have and then jumps to step (1);

(3) motion outline part that Difference Calculation is gone out is synthesized in the multimedia that will show by virtual reality 3D synthetic method and shows, and then jumps to step (1).

Beneficial effect of the present invention:

Owing to adopt detection method of the present invention, only need the camera of a USB interface, directly insert main frame, do not need to install capture card transducer is carried out data acquisition, reduced the complexity of cost and installation.Measured object need not to carry any induction positioner, can detect, and is convenient and practical.And the scope that camera is taken is greater than the induction range of infrared inductor, thereby has enlarged the scope that detects.

Description of drawings

Accompanying drawing is a method flow diagram.

Embodiment

Shown in accompanying drawing.

Start the coupling thread, the thread step comprises:

(1) get the image that current camera photographs, putting the current shooting image is this image;

(2) whether piece image is empty in the judgement, is sky, and then putting piece image is present image, jumps to step (1); Then two accompanying drawings are not carried out Difference Calculation for sky, putting piece image is present image, has motion then to jump to step (3) according to difference result, does not have and then jumps to step (1);

(3) motion outline part that Difference Calculation is gone out is synthesized in the multimedia that will show by virtual reality 3D synthetic method and shows, and then jumps to step (1).

The present invention is applied in the scientific and technological museum product, and wherein " Spider-Man " scientific and technological showpiece promptly is applied to the method for the invention.The main hardware structure of system: camera, computer and projector.Utilize camera to take the preceding image of projection screen, utilize motion detection to judge whether that the someone participates in, sometimes movement human is scratched picture and be synthesized on the cobweb, according to the pulling of position display people on cobweb and the vibrations of cobweb of people's motion.

Claims (1)

1. the method based on the motion of image motion inspected object starts the coupling thread, and the thread step comprises:

(1) get the image that current camera photographs, putting the current shooting image is this image;

(2) whether piece image is empty in the judgement, is sky, and then putting piece image is present image, jumps to step (1); Then two accompanying drawings are not carried out Difference Calculation for sky, putting piece image is present image, has motion then to jump to step (3) according to difference result, does not have and then jumps to step (1);

(3) motion outline part that Difference Calculation is gone out is synthesized in the multimedia that will show by virtual reality 3D synthetic method and shows, and then jumps to step (1).
