Problems solved by technology

When the camera is installed on a mobile vehicle, the problems to be faced in processing and analyzing the captured images include continuous changes in the image background, moving objects are relatively small compared to a wide area, and the moving speed is relatively slow. The detection of moving objects in aerial images is more complicated than that of fixed cameras

Embodiment Construction

[0078] The implementation example of the present disclosure is aimed at continuous images, based on frame difference calculation, image segmentation and other technologies, combined with progressive morphing-based technology, to automatically and completely detect the position and outline of moving objects. It can also be combined with moving object tracking technology to shave false alarm information, and use its prediction and correction characteristics to obtain stable and accurate moving object detection results. The connotation of this implementation example is described in detail below.

[0079] Figure 4 is a schematic diagram of an example of a mobile object detection device, which is consistent with some disclosed implementation examples. exist Figure 4 In the example of , the mobile object detection device 400 includes a frame difference module 410 , a candidate region search module 420 , and a mobile object fusion module 430 .

Abstract

The invention provides a device and a method for movable object detection. In the invention, a frame difference image corresponding to two continuous images is calculated according to every two continuous images of a movable object, a present time image is divided into a plurality of connatural areas, a plurality of uniform blocks are judged from the divided areas, at least one candidate area is detected from the uniform blocks, the frame difference image and the at least one candidate area are converged to obtain both the position and the integral profile of the movable object by the assistance of the gradual deformation technology.

Description

technical field [0001] The invention relates to a moving object detection device and method. Background technique [0002] Surveillance systems often set up fixed cameras next to the scene for monitoring. When analyzing images, techniques such as background subtraction or frame difference can be used to eliminate the background and detect moving foregrounds. When the camera is installed on a mobile vehicle, the problems to be faced in processing and analyzing the captured images include continuous changes in the image background, moving objects are relatively small compared to a wide area, and the moving speed is relatively slow. The detection of moving objects in aerial images is more complicated than that in fixed cameras. [0003] Research on related technologies such as the use of automatic intelligent visual surveillance technology in future cities and battlefields. The detection of moving objects uses the affine warping technology of the affine model to align the cont...
