The invention discloses an image processing method based on a Direct three dimensional (3D) technology. The image processing method comprises the following steps of: creating a surface, a first texture, a second texture and a graphic pipeline through the Direct3D technology; transmitting image data to the surface; transmitting the image data in the surface to the first texture; transmitting the image data in the first texture to the second texture; and processing the image data by using the graphic pipeline. The invention also discloses an image processing device based on the Direct 3D technology. The image processing device comprises a creating module, an image data transmitting module and an image data processing module. The surface created in a video memory directly receives the image data; the textures created in the video memory receive the image data in the surface; and the graphic pipeline processes an image. Because the image data are not required to be transmitted through an internal memory of a system in a transmitting process, and are not transmitted through a central processing unit (CPU) either, the processing speed of the image is increased, and the display efficiency of the image is improved.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method based on Direct3D technology and an image processing device based on Direct3D technology. Background technique [0002] At present, image acquisition cards generally use Direct3D technology to display captured image data. In order to use the Direct3D graphics pipeline to process the image data captured by the capture card, the general method is to first send the image data to the system memory, then create a dynamic texture based on the image data in the system memory, and then use the Direct3D graphics pipeline to complete the processing of the image data and show. In this way, before the image data is processed, the image data needs to be sent from the system memory to the video memory, and then the graphics pipeline in the video memory can be used for processing. That is, the image data needs to be transmitted between the system me...
