Embodiment Construction

[0037] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0038] The visual cognition model-driven global image information synthesis method provided by the embodiment of the present invention is a method for synthesizing several global images containing complex multi-dimensional moving objects in a scene into a large scene image. In order to facilitate the description of the method provided in this embodiment, in this embodiment, firstly, in an indoor environment, the camera is mounted on a stable and movable platform, and the camera is rotated horizontally at a constant speed to scan, and at the same time, it performs translational movement with the platform on which it is carried. group contains a series of images of dense video sequences of scenes with complex human movements. Then the collected dense video...

Abstract

The invention provides an overall image information synthetic method driven by a visual cognition model, which comprises the following steps: creating a image significance visual cognition model, and defining a column width selection driving energy function for the overall image information synthesis; structuring an overall image information composite image model, defining a node and computing the connecting side weight of the node; adopting the Dijkstra algorithm to search in the overall image information composite image model to enable the overall composite image significance visual cognition difference to reach the minimum clipping path; and selecting certain pixel column width in each frame of image in intensive video sequence images according to the minimum clipping path order, arranging the selected pixel column width according to sequence code, and synthesizing the pixel column width into overall composite image. According to the method, the function of visual cognition model of people on the overall scene picture synthesis can be fully expressed, synthesis flaw caused by multi-dimension mobile interference can be reasonably avoided, and key contents of wide large-scale scene can be effectively repeated.

Description

technical field [0001] The invention relates to the field of computer vision, and relates to a large field of view image synthesis technology, in particular to a global image information synthesis method driven by a visual cognition model. Background technique [0002] Wide-area and large-field-of-view image information acquisition and processing technology has had an important impact on the development of many disciplines, and has extensive demands in many fields such as national defense, security, and civil security. However, due to the limitation of the manufacturing process of photosensitive components of camera equipment, the field of view of ordinary camera equipment is far from the size of the human eye field of view. More and more applications require image information with a larger field of view and higher resolution. Improve system reliability and security. In particular, in the security investigation system, the acquisition of wide-area field of view image inform...
