3518E平台的搭建
海思的SDK提供了ISP调试的相关工具，降低了IPC开发ISP调试的难度。初次搭建ISP调试环境，记录一下。 SDK版本：Hi3518_MPP_V1.0.A.0 硬件平台：HI3518E_OV9732
工具包：PQ_TOOL (Hi3518E_V100R001C01SPC0A0\\01.software\\pc\\PQ_TOOL)
文件说明：Hi3518_ITTB_MPP2_V1.0.A.0_B030.tgz 设备端工具 ； PQTools_V3.7.5.zip PC端工具 环境搭建步骤：
（1）将Hi3518_ITTB_MPP2_V1.0.A.0_B030.tgz拷贝至nfs共享目录名，解压后运行HiIspTool.sh脚本 倘若用海思自带的工具出图像并调节ISP运行：
#./HiIspTool.sh -a -p ov9732_720p_line.ini ps一下可以看到两个进程
696 adminlvj 58488 S ./ittb_stream -p ov9732_720p_line.ini 699 adminlvj 19676 S ./ittb_control
倘若运行自己的工程出图像了，这时只需要运行一下命令即可。 #./HiIspTool.sh -a ps一下可以看到一个进程
699 adminlvj 19676 S ./ittb_control
（2）PC端直接解压PQTools_V3.7.5.zip，运行HiPQTools.exe，输入选择sdk版本Hi3518_MPP_V1.0.A.0 ，输入设备IP，就可以连接上摄像头
倘若运行了ittb_stream，可以PC端软件上打开视频图像窗口
连接成功，至此，最简单的ISP调试环境搭建就完成了。复杂的就是后面的ISP调节过程了。
备注：
运行脚本的时候可能会报错，查看相关打印信息，将错误消除。当前产品我们用的是HI3518E+OV9732，SDK中并没有提供相关的sensor库和相关的config文件，所以运行报错了！
解决：将OV9732sensor库拷贝至Hi3518_ITTB_MPP2_V1.0.A.0/libs/下，将ov9732_720p_line.ini拷贝至Hi3518_ITTB_MPP2_V1.0.A.0/configs/下
