Happy Anniversary (plus announcements)!
A year ago today, at 8:58AM PST, we took a deep breath, logged into our Kickstarter account, and clicked the big “Launch Campaign” button in our creator console. We had no idea what might happen over the following 45 days - or, for that matter, the following year.
Needless to say, we were overwhelmed with the Kickstarter community’s response on that first day, and we’ve continued to be amazed at what you have collectively done since our launch a year ago.
Since then, we’ve also endeavored to deliver to you, our backers, everything we promised we would: a beautifully designed, well crafted and highly capable piece of hardware; sample apps that let you explore multiple possibilities; and a well-documented, robust SDK that makes developing with depth on mobile devices simple. We hope that we’ve exceeded your expectations so far. And, with that said, we’ve got more for you.
Calibrator is a very important app for all Structure Sensor owners. This is the app that will find the precise alignment between the Structure Sensor and the iPad color camera.
Best of all, you can download it as of today on 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 Calibrator work? Calibrator 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 is the end result? Take a look at the two images in the screenshot below to see how Calibrator's precise alignment of the iPad color camera and Structure Sensor depth camera allows for a significant improvement in the quality of color textures on 3D models, for example.
What's next now that Calibrator has arrived? We're glad you asked! Because...
Color scanning has arrived.
Once you download and launch Calibrator, your iPad’s color camera will be precisely aligned to your Structure Sensor’s depth camera. That means you’ll be able to use the Scanner sample app and Skanect (via the Structure app) to capture objects, people and more in full color. What will that look like? Here are the first two examples:
Capturing an object with the Scanner sample app from the SDK:
And now, with color enabled:
So when will color be enabled in the Scanner sample app and Skanect? As a matter of fact, updated versions of the Scanner sample app and the Structure app are already ready for download from the App Store today! Update your Scanner sample app and Structure app now.
What About Room Capture and SDK Update?
Calibrator has paved the way for the Room Capture sample app and the SDK update is also nearly ready. Keep an eye out for another backer update coming soon after this one.
Video: Inside Your Structure Sensor
The Structure Sensor’s simple exterior hides a fascinatingly complex interior full of optics, processors, PCBs and more. We wanted to reveal some of the hidden design and attention to detail that collectively made the Structure Sensor possible.
Because you were the first to back the Structure Sensor, you also get to be the first to see the new design video. So, without further ado, we’d like to present the world premier of the new Structure Sensor design video:
Looking forward to another amazing year of progress. We're glad to have you onboard!
