Embodiment Construction

[0008] combine figure 1 and figure 2 Describe this embodiment, an intelligent Camera Link to SDI device, the device receives the image data output by the camera through the Camera Link interface, sends it to the FPGA, and sends it to the VP port of the DM642 after denoising processing, and the DSP processor uses EDMA The image data is stored in SDRAM by means of external commands or image quality. Here, a series of intelligent image enhancement processes such as grayscale stretching and pseudo-color processing can be performed on the image data according to external commands or image quality. After being processed by the SDI module output unit, the SDI Serial digital interface output.

[0009] The software flow of this embodiment is: 1. Image acquisition: the Camera Link channel collects the camera image into the SDRAM of the DSP processing board; 2. Denoising filtering: the camera image collected under different environments may be interfered by various complex noises , in...

Abstract

An intelligent device for switching Camera Link to a serial digital interface (SDI) relates to the technical field of image processing and solves the problems that the existing various cameras based on a Camera Link interface can not display on a monitor directly and quality of displayed images is poor. The device comprises a field programmable gate array (FPGA), a digital signal processor (DSP), a synchronous dynamic random access memory (SDRAM) and an SDI module. The Camera Link interface receives image data output by a camera and transmits the image data to the FPGA, the FPGA conducts noise-reducing processing on the received image data and transmits the image data to the DSP, and the DSP receives the image data through a video port (VP), transmits the image data to the SDRAM to be stored in an EDMA mode, reads the image data in the SDRAM in an external memory interface (EMIF) bus mode and processes the data, and transmits the processed image data to the SDI module. Use and carrying of the device are convenient.

Description

technical field [0001] The invention relates to the technical field of image processing. Background technique [0002] At present, various cameras based on the Camera Link interface cannot be directly displayed on the monitor. They can only be connected to the system machine through a special acquisition card and displayed on the monitor of the system machine. The system is relatively large and inconvenient to use; The developed special collection and display interface shows that the versatility is relatively poor. At present, many sensors in the photoelectric measurement and control equipment in service on the test range use the Camera Link digital interface. Since this interface cannot be directly displayed, only converted analog images can be sent in real time for observation. When digital images are converted into analog images, the image quality will inevitably cause loss, which will have a certain impact on real-time observation and judgment. How to realize the lossl...
