Embodiment Construction

[0049] The present invention will be further described below in conjunction with the accompanying drawings. Such as figure 1 As shown, a method for constructing a color background of a gray-scale target image, using an infrared camera to capture multiple color scene images; obtaining a panorama of a fixed area through image stitching technology; and then using an infrared camera to obtain a certain part of the panorama information The gray-scale scene graph; then, pixel-level scaling is performed on the same object in the panorama image and the gray-scale scene graph, so that the size of the gray-scale scene graph is scaled to the same size as the corresponding position in the panorama image. Finally, the color background image at the same position as the grayscale scene graph is obtained from the panorama through template matching.

[0050] The present invention is not limited to this embodiment, and any equivalent ideas or changes within the technical scope disclosed in th...

Abstract

The invention discloses a method for constructing a color background of a grayscale target image, comprising: adopting an infrared camera to capture a plurality of color scene images; obtaining a panorama of the fixed region through image stitching technology; then acquiring a part of the grayscale scene graph in the panoramic information by using the infrared camera; performing pixel-scale scaling on the same object in the panorama and grayscale scene graph, so that the size of the grayscale scene graph is scaled to the same size as the corresponding position of the panorama; and finally, obtaining the color background image at the same position as the grayscale scene image from the panorama by template matching. The invention avoids the information distortion problem caused by directly coloring the color image, and may highly restore the scene information. The invention utilizes the scale invariance of the SIFT features in the prior knowledge to obtain a good detection effect. The invention obtains a color background image skillfully by using the image processing method, which is less in time consuming, low in cost and high in precision.

Description

technical field [0001] The invention relates to image processing technology, in particular to a method for constructing a color background of a grayscale target image. Background technique [0002] With the continuous development of information technology and the experimental requirements based on the Huludao project, it is necessary to be able to automatically obtain the color scene information of a certain area in harsh conditions such as night fog, so that the required scene information can be accurately obtained under any circumstances, so that Make certain contributions to the field of video surveillance security. [0003] The color background construction is actually to color the grayscale image, that is, the pseudo-color processing technology. The reason is that the characteristics of the human physiological visual system are not sensitive to small grayscale changes, but are extremely sensitive to small differences in color. Human eyes can generally only distinguish ...
