中文摘要:随着高品质相机的普及和图像处理领域的不断发展，人们对图像质量提出了更高的要求。现有的工业相机采集到的图像信息都存在一定的色偏现象，一般需要图像处理器（Image Signal Processor，ISP）对图像进行处理。白平衡处理作为ISP处理中一个非常重要的功能，直接决定着图像信息的色彩效果。本文基于Vitis HLS平台实现了AXI-stream视频流接口的白平衡算法IP，同时基于ZYNQ的ARM+FPGA的片上系统对IP进行了上板验证。本算法IP在1920×1080@60fps的视频流下保证了算法的实时性，同时对图像具有良好的校正效果。

Implementation of Automatic White Balance Algorithm Based on HLS

Abstract:With the popularity of high-quality cameras and the continuous development of image processing, people have put forward higher requirements for image quality. The Image information collected by existing industrial cameras has certain color bias phenomenon, which generally requires Image Signal Processor (ISP) to process the image. As a very important function in ISP processing, white balance processing directly determines the color effect of image information. In this paper, the white balance algorithm IP of AXI-stream video stream interface is implemented based on Vitis HLS platform, and the on-chip system based on ZYNQ ARM+FPGA verifies IP on the board. The IP address of the algorithm in 1920×1080@60fps ensures the real-time performance of the algorithm and has good image correction effect.
