Embodiment 1

[0052] This embodiment provides a method for camera image acquisition and processing based on FPGA+DSP architecture, such as image 3 As shown, image 3 It is a flowchart of a method for camera image acquisition and processing based on FPGA+DSP architecture according to the first embodiment of the present invention, including the following steps:

[0053] Step S301: FPGA collects the original image data output by the camera of the Cameralink interface;

[0054] In the embodiment of the present invention, the Cameralink interface camera is connected to a video capture card for capturing video images. The video capture card uses the TL288A CameraLink video capture card. After the TL288A CameraLink video capture card collects the video images, the original video image is captured through the Cameralink interface. The data is transmitted to the FPGA, and the FPGA is set on the TL6657F-EasyEVM board. Before the FPGA collects the raw image data output by the Cameralink interface camera, i...

Abstract

The invention discloses a camera image collecting and processing method and system based on FPGA (Field Programmable Gate Array)+DSP (Digital Signal Processor) architecture. The method comprises the following steps that: the FPGA collects original image data output by a Cameralink interface camera; the FPGA caches the original image data; the FPGA transmits the cached original image data to the DSP; and the DSP processes the original image data to obtain a target image. Through the method, instantaneity for collecting and processing the image data of the Cameralink interface camera is improved, and in addition, the volume and the power consumption of equipment which processes image data are small.
