The company is nearly done shipping the $399 devices to its crowdfunding backers (non-backers who buy one now can expect delivery in about a month), but we managed to finagle a couple of days with an early production version of the Structure Sensor to get a peek at how it performs in the real world. They also sell a ‘Hacker cable’ which allows the Structure to be plugged into a regular USB port.Last year, California-based Occipital closed out a wildly successful Kickstarter for its Structure Sensor, an iPad-mountable structured light scanner that can perceive the world in three dimensions by projecting infrared dots on things. Occipital is supporting the open source community, and accomodates access to different platforms as a result, by hosting interface software OpenNI2 on a Github Repository. The Structure Sensor is enclosed in a sturdy brushed aluminum housing. The Structure does not have a color camera or microphones in it, but for a lot of applications this is a good thing. It’s easy to imagine this being attached to a Jetson platform (robot, tablet, DSLR, etc) and used for depth sensing. With the appropriate cables, the Jetson is able to interface with the Structure Sensor.Īs the video shows, the Structure Sensor is considerably smaller than the original Kinect. Inside the open source community, there is a project called OpenKinect which enables interfacing with a PrimeSense device and provide depth streams, infrared streams, color streams, sound, etc. An infrared camera then views the scene, and by determining the deformation of the pattern calculates the depth of each point. A simplistic explanation is that an infrared laser (!) is shone through a patterned film, the pattern on the film being known. The PrimeSense (recently acquired by Apple) method of depth sensing uses a structured light technique. (Microsoft has since moved to a different approach for depth sensing for the second generation Kinect 2). The key is that the device is based on PrimeSense technology, which is what the original Kinect 360s were based on. So why is this device interesting? You attach it to an iPad or iPhone after all. You can find out more about the Structure Sensor here: Structure. The video shows the unboxing and installation of the Structure Sensor to the Jetson TK1 development kit.
