Meet Calibrator - a very important app we've been working on for all Structure Sensor owners. This is the app that will find the precise alignment between the Structure Sensor and the iPad color camera, and we're just about to submit it to the App Store.
Once you connect your Structure Sensor and launch Calibrator, you're asked to move around and pause so that pictures can automatically be taken of the scene. After enough information has been collected, there is a final opportunity to refine the depth and color calibration before it's saved to the Structure Sensor. After going through the process once, the calibration will be used in all apps that use the Structure Sensor built with the Structure SDK. If you have multiple iPad devices, you can calibrate the sensor one time on each device, and the correct calibration will be selected automatically.
How does it work? Calibrator itself is an advanced application that automatically finds correspondences between the iPad camera and Structure Sensor IR camera. Thanks to the precise iPad brackets, most of the work is done for us, but there’s still precision adjustment to be done to compensate for tiny variation in assembly. Potential feature matches are automatically verified using computer vision and used as part of an advanced optimization that finds the exact offset between these two cameras.
What's next? The upcoming Room Capture sample requires precise calibration, so now that we have Calibrator ready for you, we've already begun work preparing Room Capture for release. Stay tuned for updates about Room Capture as well as color object scanning.
