给出立方体六个面合成一张全景图
二、主要知识py360convert
2.1、该项目的特点
立方体贴图和等矩形之间的转换 等角于平面 纯python实现仅依赖于numpy和scipy矢量化实施在大多数地方 c2ee2c在1.6 GHz Intel Core i5 CPU上花费300ms并花费160ms
2.2、安装
pip install py360convert现在您可以在任何地方import py360convert或使用命令行工具convert360。
2.3、参数
e2c(e_img, face_w256, modebilinear, cube_formatdice)
将给定的等矩形转换为立方体贴图。参数
e_img形状为[HWC]的块状数组。face_w每个立方体面的宽度。modebilinear或nearest。cube_format请参阅c2e说明。
e2p(e_img, fov_deg, u_deg, v_deg, out_hw, in_rot_deg0, modebilinear)
从给定的等角线拍摄透视图。 参数
e_img形状为[HWC]的块状数组。fov_deg以int或tuple给出的视野(h_fov_deg, v_fov_deg)。u_deg水平视角在[-pipi]范围内。-左/ 右。v_deg垂直视角范围为[-pi / 2pi / 2]。-向下/ 向上。out_hw(height, width)以元组输出图像。in_rot_deg平面内旋转。modebilinear或nearest。三、示例
