| Abstract: | The embedded system,capture and stitching of multi-channel images based on vehicle-mounted UAV is designed to improve the efficiency of capturing panoramic images.The system is composed of high performance images codec processor based on ARM kernel,the image sensors and Linux.It is very suitable for UAV platform.The system can capture the images in different angles in multithreading mode in real-time and synchronously,have the panorama images with the images stitching interface based on Qt and OpenCV.The results of experiment show that the system can capture images synchronously and stitch images successfully,its operation is convenient and achieve expected effect. |
