It is reported that the structure sensor series is a portable 3D sensor specially designed for IOS devices. Since the launch of the first st01 in 2014, it has been used in a variety of scenes, including scanning patients' limbs (only a few minutes), customizing orthopedic machines and artificial limbs, and also in industrial design, construction and other scenes. With the support of IMU sensor and higher resolution, Mark II can support better 3D spatial perception and bring better 3D experience for arkit application。
Some of the components previously used in st01 are provided by primesense. This major update should have something to do with Apple's acquisition of primesense. It is reported that occipital almost redesigned the Mark II based on the experience of st01 development. The 3D capture scheme used in the sensor is changed from the original structured light to the active stereo type, and the effect is good enough in the sun. The optical elements mainly include a pair of infrared sensors and a laser projector. The infrared sensor can use the global shutter to capture high-precision data, while the laser projector supports high contrast, resulting in larger scanning range and doubled depth resolution, more details can be seen, and safer for the human eye。
It is understood that the Mark II mentioned earlier is smaller, 38% thinner and 31% lighter than the previous generation. In addition, Mark II also uses the optimized structure SDK to achieve higher quality 3D scanning, support environment mapping, 6DOF tracking and other functions。
At present, Mark II has started pre-sale and will start shipping in August. Mark II is not applicable to Android devices, but structure core supports Android, windows, Linus, Mac OS and other operating systems, and its alleged effect is comparable to that of hololens's sensor module. The official website price is also $399。
