摘要
为提高双曲面折反射全景成像系统柱面展开图像的质量,根据双曲面反射镜的性质,给出了全景图像柱面展开方法的数学模型。提出以图像分辨率和像素有效率作为图像展开质量的衡量指标,分析了2个指标随起始入射角和入射角跨度变化的规律,得出了柱面展开时起始入射角和入射角跨度的选择范围,仿真结果和实测数据实验验证了结论的正确性。
In order to improve the cylinder image quality of hyperbolic-catadioptric panorama image system,this paper introduces the unwraping mathematics model of panorama image system based on the property of hyperbolic reflector.Taking the image resolution and pixel efficiency as evaluation parameter,this paper analyses their variation rule along with the start angle and the span of incidence,points out their choice range for unwrap the panorama image.The simulation results and measure data experiments prove that the conclusion is correct.
