Camera Calibration

is the image calibration part where the geometric and photometric information about the data set is extracted.

Calibration is the process of finding the true parameters of a camera that produces a certain given image. The camera parameters include the internal parameters like the focal length, principal point and lens distortion of the aquisition device and the external parameters that encode the geometric position and orientation of the device in the world.

Our PixelScanner software, using image information alone, finds both the extrinsic and intrinsic parameters and outputs a sparse model of the scene. It is also possible to extend the calibration to metric in case it is necessary to make measurements on the final 3D model. Additionally, if GPS information is available, geo-referenced calibration is generated automatically.
