目前数字相机逐步取代模拟相机应用在光电测量设备中,因此图像处理器也逐渐转化为接收数字视频的接口,对数字图像处理器检测的信号发生器的研制也变得十分迫切。本文介绍了一种基于FPGA的两种数字视频格式输出的视频发生器,它可以产生LVDS制式的数字视频信号和CamerLink制式的数字视频信号,而且可以通过串口对产生的视频中的目标大小、运动速度、灰度及背景灰度进行实时更改。它满足了对数字视频输入的图像处理平台的检测,具有一定应用前景。
At present, the digital camera gradually replaces the analog camera used in the photoelectric measuring equipment, so the image processor is gradually transformed into the interface for receiving the digital video, and the development of the signal generator detected by the digital image processor becomes very urgent. This article describes a FPGA-based video output of two digital video formats, it can produce LVDS standard digital video signals and CamerLink standard digital video signals, but also through the serial port on the video generated by the target size, movement Speed, grayscale and background grays for real-time changes. It meets the digital video input image processing platform for testing, has certain application prospects.
