本文提出了一种包含线性投影特性的折射式全方位传感器反射镜的一般设计方法，即所谓的恒定分辨率相机。线性度是指3D距离(或角度)和像素坐标之间的关系。我们列举了标准(笛卡尔像素分布)和对数极轴相机的三个有趣的线性约束的实际案例：恒定的垂直、水平和角度分辨率。最后，结合一些实际案例，将该公式应用于相机的设计中。结果图像表明，设计是成功的，因为获得了预期的线性特性。
In this paper we present a general methodology for designing mirrors of catadioptric onmidirectional sensors encompassing linear projection properties, the so called constant resolution cameras. The linearity is stated between 3D distances (or angles) and pixel coordinates. We include three practical cases of interest of linear constraints for both standard (cartesian pixel distribution) and log-polar cameras: constant vertical, horizontal and angular resolution. Finally, the formulation is applied in designing a camera combining some of the presented practical cases. Resulting images show that the design was successful as the desired linear properties were obtained.
