Problems solved by technology

Therefore, in the current stitching process of multiple JPEG images, whether it is decoding, encoding, or spatial domain image stitching, it needs to consume more memory and computing resources of hardware devices, and increase the power consumption and computing power of hardware devices. Time, bring a greater burden to hardware equipment
Also, the burden increases as the resolution of the image increases

Abstract

The invention provides a traffic image splicing system and method, wherein the system comprises an image obtaining device which is used for obtaining a plurality of traffic images, and transmitting the plurality of traffic images to a splicing device; and the splicing device which is used for splicing the compressed code streams of the plurality of traffic images to obtain a target code stream ofa spliced image obtained by splicing at least along the width direction of the images. Therefore, the steps of decoding the compressed code streams of a plurality of traffic images, splicing all decoded spatial domain reconstructed images, encoding spliced images obtained through splicing and the like are eliminated, the memory and operation resources of hardware equipment are saved, and the operation efficiency of the hardware equipment is improved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a traffic image mosaic system and method. Background technique [0002] With the development of image processing technology and users' demands for higher and higher image clarity, the resolution of images collected by current image sensors is also getting higher and higher. However, since the storage space occupied by the image and the amount of transmission required for transmission are positively related to the resolution of the image, in order to reduce the storage cost and transmission cost, it is necessary to compress the image data, that is, to perform encoding processing to reduce the image resolution. Storage capacity and transmission capacity. Correspondingly, when an image needs to be viewed, the image coded data (that is, the compressed code stream) must be decoded to display the image screen. [0003] Among them, multiple images taken at different times wil...
