Embodiment Construction

[0023] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the embodiments are not intended to limit the present invention.

[0024] refer to figure 1 Shown, a kind of multi-channel video image splicing method of the present invention, the steps are as follows:

[0025] (1) Acquire the image data of each video at the same moment, and stitch the images, and calculate the pixel coordinate position mapping transformation matrix from the original image to the spliced ​​image and the mask matrix (mask matrix) for pixel value transformation;

[0026] The calculation of the pixel coordinate position mapping transformation matrix is ​​specifically: use the accelerated robust feature (SURF) algorithm to obtain image feature points, and eliminate the feature points in non-image overlapping areas; use the nearest neighbor and...

Abstract

The invention discloses a multi-channel video image splicing method, which comprises the following steps of: acquiring image data of each channel of video at the same moment, splicing images, and calculating a pixel coordinate position mapping transformation matrix and a pixel value transformation mask matrix from an original image to a spliced image; acquiring images in a video stream during actual splicing, carrying out mapping transformation and mask matrix transformation on each frame of image by using a kernel function, realizing mapping transformation on pixel coordinate positions, and realizing mask matrix transformation on pixel values, so as to obtain a spliced image; and calling the trained model to carry out target identification and tracking on the spliced image. The splicing principle is fully understood, the splicing process is converted into transformation of pixel point positions and pixel values of all paths of images from a mathematical angle, a mapping matrix of pixel position coordinates and a mask matrix of pixel values are analyzed, and the splicing process is more accurate no matter how many paths of videos and no matter the sizes of video image pixels, parallel splicing can be realized on the graphics processor by adopting the method.

Description

technical field [0001] The invention belongs to the technical field of video image algorithm improvement, and in particular relates to a multi-channel video image splicing method. Background technique [0002] With the rapid development of China's civil aviation, aviation support resources are becoming more and more tense, and the units involved in the aviation support process are intricate, and the traditional ramp management concepts and management methods are facing great risks. In order to improve the efficiency of flight support and improve the quality of airport operation under the condition of limited ground support resources, new apron control requirements are put forward. [0003] Regional airports and general-purpose airports are limited to small flights and limited daily income. According to traditional airport construction and control construction planning towers, their construction costs and operating costs cannot be offset within the normal operating cycle to o...
