Getting camera (calibration) properties

CesiumJS
1

Hello!

I wish to estimate the camera position using the cesium images. To do this, I need to understand the camera used in terms of its focal length, camera rotation matrix and translation vector, basically transformation matrix used to convert the 3D positions to the 2D (pixel or picture reference frame) coordinates in the image. Is this something that can be manually defined? Is there any default setting?

Thanks in advance!

You can get the camera’s full transform matrix here: https://cesium.com/docs/cesiumjs-ref-doc/Camera.html?classFilter=Camera#transform

This sounds like an interesting project - what are you working on?
