Creating A Calibration

preparation before creating a new calibration make sure you have the following equipment and information ncam equipment rigged and connected to the camera chosen lens encoding option connected and selected in ncam reality preferences calibration chart, " 70mm mosaic " is preferred sensor size information for your camera all calibration is conducted using the full ui first steps to create a new calibration press the " create calibration " button in the calibration panel this will display the calibration window shown below some fields may be automatically populated from previously entered information, this can be changed if it is no longer relevant camera settings begin by defining the name and brand of the camera you are using, be sure to give it a unique id so that you are able to identify it later enter sensor size information by pressing the " create sensor " button this will bring up the sensor size window for information on how to use this then please see the linked page using a template if an existing calibration for that camera already exists, then it can be selected from the " use template " dropdown this will utilise the camera information from that calibration and mean that manually entering information and using the sensor size window is not required if using a template, make sure it uses the same sensor size as the mode you're now in lens settings define a name, brand and unique id/name for your lens use the " focus " " zoom " and " iris " sections to enter information about the lens using a template if an existing calibration for that lens already exists, then it can be selected from the " use template " dropdown this will utilise the lens information from that calibration and mean that manually entering information is not required map lens unless your lens has been set to be completely " static " in the previous section, then lens mapping will be required this is a process that correlates the information from the lens encoders with the physical values from the markings on the lens barrels press the " map lens " button to enter the encoder mapping window for detailed information on how to map the lens please see the attached link create golden point finally, press the "create golden point" button this will take you to the lens calibration screen where the fov and distortion of the lens will be calculated using a calibration chart for information on how to use the lens calibration window please see the attached link to be able to save a calibration the golden point must be completed as a minimum be aware that in most circumstances more calibration is required additional calibration points after creating a golden point, it is recommended to test the quality of the lens calibration for this part of the lens continue by conducting the camera bar to main calibration and placing the zero point within your environment this will allow you to return to the lens calibration window and continue with the remaining calibration of the lens this can be done by choosing the edit calibration option from the calibration panel
