image surface curvature的意思|示意

Image can be regarded as curved surface, and Gaussian Curvature can be used to describe the curves degree of curved surface relative to ball.

图像可以看作是一个曲面，描述曲面上某点相对于球面的弯曲程度可以用高斯曲率。

Firstly, this paper assumes that the surface of range image is piecewise smooth, and estimates curvature from the smooth piece of surface to which the current point belongs.

首先，提出曲面是分片光滑的假设，表面曲率需从该像素所属的光滑曲面片来估计。

The shape of the detector must match the varying curvature of the image surface to accommodate continuously adjustable zoom, and this is easily done with this new hemispherical eye camera.

检测器的形状必须与图像表面改变的曲率匹配，以适应持续调整的变焦镜头的变化，而这，用这种新型的半球眼式相机可轻易做到。
