Method for detecting movement of airborne displays

Abstract

The invention relates to a method for detecting movement of airborne liquid crystal displays, and belongs to the field of movement detection. The method includes steps of firstly, modeling backgrounds; secondly, carrying out subtraction on the backgrounds to acquire moving targets; thirdly, detecting the moving targets in continuous video images by the aid of inter-frame difference processes, to be more specific, optionally selecting two frames of continuous video sequences, computing difference images G(x,y), extracting the moving targets by the aid of difference between pixels of the images of the continuous video frames, generating binary images, carrying out morphology filtering on the binary images, analyzing and judging connectivity of the images, determining that the targets are detected and regions are provided with the moving targets if pixel numbers of the certain connective regions are larger than given threshold values, and marking the moving targets in the original images according to moving target positions determined by the connective regions. The method has the advantage that micro-movement of objects can be monitored by means of combining movement detection algorithms with video monitoring technologies.

Description

technical field [0001] The invention belongs to the field of object motion detection, and in particular relates to a motion detection method for an airborne display. Background technique [0002] In the modern military field, the long-distance monitoring system plays an important role. The weapons and equipment equipped with long-distance monitoring are all over the sea, land and air combat platforms, and are applied to large, medium and small weapons and equipment; although, the long-distance monitoring equipment can zoom in on distant objects and display On the display screen, however, the slight movement of an object that cannot be observed by the human naked eye or the fatigue of the human eye may easily cause certain movements to be undetectable. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a motion detection method for an airborne display with a motion detection function, which monitors tiny...
