If point cloud and imagery don't match perfect and the exact camera calibrations (lever arms and delta heading/pan, tilt/pitch and roll) are not known, Orbit is able to calculate these camera calibration values.
This page describes how to provide the required information in order to create the perfect calibration and Orbit Import Template.
Import your Mobile Mapping data in Orbit using a temporary template :
To create a good set of reference points we advise using the Asset Inventory procedures and the Inventory Theme which one you can download below.
Download and Import this Theme into your Orbit AI installation.
A calibration point or reference point is a clearly identifiable position in the Point Cloud and on an image, with following information :
Use the Asset Inventory procedure "Add inventory simplified" to measure these calibration points :
At least 12 calibration points using 4 or more reference images are required to make a good calibration possible.
It is advised to have a well-distributed set of points along the run and on the image. Calibration points in all quadrants are a must.
Take your time to create a good calibration dataset. Measure carefully and work precise. It is a one time effort for all feature imports.
Sent the Calibration Points and the Photo Position dataset to support at orbitgis dot com.
This calibration tool is not available in the current release. But one of our support engineers will process your request and create your customized import template.
Export the Inventory Theme used to collect the Calibration Points :
It is not required to export the used photo positions. You can sent the whole photo position dataset.
Copy this dataset from the Orbit Run directory :
Copy the import conifugration file :
Provide one sample image.
