相机

This panel contains all settings of the camera used for filming the movie which is currently being edited in the Clip editor. Different predefined settings can be used here and can be chosen from the panel header. But such settings as distortion coefficients and principal point are not included in the presets and should be filled in even if camera presets are used.

传感器宽度

在相机的CCD传感器的宽度。这个值可以在摄像头规格上找到。

像素宽高比

是CCD传感器的像素方面。这个值可以在相机规格中找到，但也可以被猜出。例如，您知道素材应该是1920×1080，但图像本身是1280×1080。在这种情况下，像素方面是：1920/1280 = 1.5。

焦距

不言自明;这是电影拍摄的焦距。它可以以毫米或像素为单位设置。

光心

Is the optical center of the lens used in the camera. In most cases it is equal to the image center, but it can be different in some special cases. Check camera/lens specifications in such cases.

镜头畸变

Mathematical function to convert distorted to undistorted coordinates.

系数

Coefficients are used to compensate for lens distortion when the movie was shot. Currently these values can be tweaked by hand only (there are no calibration tools yet) using tools available in Distortion mode. To do this tweak K1 until the solving is the closest to the known focal length (but also take grid and annotations into account to prevent “impossible” distortion).
