Abstract

The invention relates to the technical field of three-dimensional image processing, and in particular relates to a three-dimensional image processing system based on depth perception. The system comprises an image acquisition module, an image preprocessing module, a three-dimensional reconstruction module, a central processing module, an interface module, a PC and a storage module. A plurality ofanalog video signals acquired by the image acquisition module are selected by a multiplexer according to needs, and are sent to an analog-to-digital video converter. Analog full-television signals CVBS output by a CCD camera are converted into digital video signals, and then the video signals enter the image preprocessing module. Images are processed to generate a main dynamic mode and an auxiliary dynamic mode. According to the invention, the purposes of large processing data volume, high processing speed and relatively simple algorithm structure are achieved; the speed and the flexibility can be considered at the same time; for a high-level processing algorithm, the data volume is small, and the algorithm structure is simple and convenient; the operation speed is high; the addressing mode is flexible; the communication mechanism is powerful; and high-speed processing application can be carried out on three-dimensional images.

technical field [0001] The invention relates to the technical field of three-dimensional image processing, in particular to a three-dimensional image processing system based on depth perception. Background technique [0002] 3D image information processing has always been a hot and difficult point in the field of image and video processing. At present, there are not many mature 3D information processing systems at home and abroad. The existing systems mainly rely on high-performance general-purpose PCs to complete image acquisition, preprocessing, reconstruction, configuration, etc. Low-level and high-level processing. The data volume of 3D image processing is extremely large and the calculation is complicated. It is difficult to meet the real-time requirements simply by relying on a general-purpose PC, which cannot meet the current high-speed 3D image processing applications.

Problems solved by technology

The amount of 3D image processing data is extremely large and the calculation is complex. It is difficult to meet the real-time requirements by relying solely on general-purpose PCs, which cannot meet the current high-speed 3D image processing applications.

[0003] Moreover, a three-dimensional image display device needs to be equipped with an image processing circuit capable of processing double the frame rate, and in order to realize such a high-performance image processing circuit, an increase in cost occurs, and a significant improvement from conventional image display devices is required. At the same time, by operating a plurality of graphics processing units in parallel, high-speed image processing can be realized without a high-performance image processing circuit. However, in the case of using a plurality of image processing circuits (graphics processing units) , also by increasing the number of image processing circuits, an increase in cost occurs
