摘要
以飞思卡尔IMX6 cortex a9 ARM平台为核心,构建嵌入式Linux操作系统。硬件上采用PCIE接口,连接4路鱼眼摄像头,编写与移植基于Linux下V4L2框架和PCIE框架的4路摄像头驱动。软件上采用开源计算机视觉库OpenCV对采集到的4路摄像头数据矫正、透视变换以及图像融合。基于Ubuntu操作系统利用交叉编译工具和CMAKE开发调试基于ARM-LINUX系统的应用,将经过变换后的全景图像在LCD屏幕上以30fps的频率显示。
The IMX6 cortexA9 ARM platform is used as the core to build the embedded Linux operating system. The hardware adopts PCIE interface to connect 4 fisheye camera,codes and transplants diver based on the V4L2 framework and PCIE framework of Linux. The open source computer vision library OpenCV is used to handle 4 channels camera data flow by the method of rectification,perspective transformation and image fusion, and cross compiler tool and CMAKE tool is used to develop and debug the application based on ARM-LINUX system by Ubuntu.Finally,the panoramic image, after the transformation on the LCD screen, is displayed at 30fps.
