+ | === Camera calibration === | ||
+ | |||
+ | The camera calibration parameters must be entered before Create Run, the 1st step of the Import Run procedure. | ||
+ | * Sensor width and height in pixels : SensorSizePIXX, | ||
+ | * Sensor width and height in mm : SensorSizeXMM, | ||
+ | * Principal Point in pixels from upper Left corner: PrincipalPointX, | ||
+ | * Focal Length in mm: FocalLenghtMM | ||
+ | * Camera radial distortion parameters: Cam_Distortion_K1, | ||
+ | * Camera tangential distortion parameters: Cam_Distortion_P1, | ||
+ | |||
+ | {{: | ||
+ | |||
+ | To facilitate import, your specific camera calibration values can be registered inside the Orbit template to avoid entering these values at import each time. Contact Orbit Support if assistance is needed. | ||
