摘要
为解决某些图像传感器多通道视频输出需实时合成为完整视频的问题,提出了一种基于FPGA的多通道视频合成方法,即四通道视频合成一路完整视频的具体实现方案。该方法通过高效利用FPGA内部存储器保证视频输出的完整性,并充分利用FPGA的高速并行性保证视频输出的实时性。通过逻辑综合和硬件测试试验表明,该方法利用FPGA实现了图像传感器多通道视频数据的合成、拼接,且视频输出实时、完整、流畅,同时FPGA可扩展应用于后续图像的预处理,从而易于实现最小视频处理及显示系统,具有良好的应用价值。
In order to solve the problem that multi-channel video of a series of image sensor needs to be synthesized into complete viedo in real time, a multi-channel viedo synthesis method based on FPGA was proposed, that is, a four-channel video synthesis method for one complete video.This method guarantees the integrity of video by using the internal memory of FPGA efficiently and the real-time performance of video by making full use of the high-speed parallelism of FPGA. Through logic synthesis and hardware testing, results show that the method using FPGA to realize synthesis and splicing of multi-channel video data for image sensors, can guarantees real-time, complete, fluent viedo. Also the FPGA in the method can be extensibly applicated for subsequent image preprocessing, which is easy to achieve minimum viedo processing and display system and has good appplication value.
