柱面投影模型将图像投影到柱状曲面，然后使用图像拼接技术进行拼接后，再将拼接结果映射回平面坐标系。本程序对图像做柱面投影，增强视觉效果-Cylindrical projection model projecting an image onto a columnar surface, then use image stitching techniques after stitching, and then map the results back to the stitching plane coordinate system. The procedure for doing cylindrical projection image, enhanced visual effects
