zynq_cam_isp_demo's Introduction

fpga-isp

本Demo基于zynq-7020(正点原子启明星+OV5640+4.3'800x480)实现了ISP图像处理(将ov5640的isp关闭,在7020上实现ISP功能),输出到LCD和HDMI,软件基于SDK裸机开发,2592x1944@15fps

Vitis/Vivado 2021.1

ISP Lite IP

位置: xil_ip_repo/xil_isp_lite_1.0

处理模块:

isp_dpc - 坏点校正 (5x5领域内的8个临近像素同时大于或同时小于中心像素,且差值大于门限,则认为坏点,使用中值替换)
isp_blc - 黑电平校正 (RGGB四通道分别减去配置好的黑电平值)
isp_bnr - 拜耳降噪 (可选择的高斯滤波器)
isp_dgain - 数字增益 (直接乘以配置好增益值)
isp_demosaic - 去马赛克 (基于边缘、色度和色差自适应插值)
isp_wb - 白平衡增益 (RGB三通道乘以配置的增益值)
isp_ccm - 色彩校正矩阵 (RGB三通道乘以配置的3x3矩阵)
isp_csc - 色彩空间转换 (基于整数优化的RGB2YUV转换公式)
isp_gamma - Gamma校正 (对亮度基于查表的Gamma校正)
isp_2dnr - 2d降噪(7x7双边滤波降噪)
isp_ee - 边缘增强 (基于特定的3x3滤波器)

统计模块:

isp_stat_ae - 自动曝光统计 (支持统计选取区域内亮度总和与像素个数,支持RGGB四通道直方图统计)
isp_stat_awb - 自动白平衡统计 (支持符合白点限定条件的RGB三通道数值总和与白像素个数,支持RGB三通道直方图统计)

注:接口时序为DVP(参考tb_dvp_helper)

VIP IP

位置: xil_ip_repo/xil_vip_1.0

处理模块:

vip_hist_equ - 直方图均衡 (可配置上下限的均衡器)
vip_sobel - sobel边缘检测 (固定的sobel 3x3卷积核)
vip_yuv2rgb - YUV2RGB色彩空间转换 (基于整数优化的转换公式)
vip_crop - 图像裁剪 (可配置裁剪区域)
vip_dscale - 图像缩小 (宽高分别支持1/N倍缩小)
vip_osd - 单色位图叠加 (用于叠加文字或logo图标例128x128)
vip_yuv444to422 - YUV444转422(做为v_frmbuf_wr源写到内存NV12,axis_422与axis_420时序相同)
