Intel RealSense Tracking Camera T265: a completely different RealSense

Over the years, Intel has cherished and developed its RealSense technology, released new versions of the RealSense SDK and new cameras - the latest model was introduced literally at the end of last year . In the article devoted to the announcement , we briefly recalled the history of the technology and its principles, without failing to emphasize that RealSense is, first of all, a depth map that gives three-dimensionality to the surrounding reality and greatly expands the possibilities of its interpretation. And here's a new twist: Intel RealSense Tracking Camera T265, which works in a completely different way, saw the light.

From a hardware point of view, Intel RealSense Tracking Camera T265 is a device equipped with two ultra wide-angle fisheye lenses (total angle of view - 163 degrees), a 6-axis inertial IMU sensor (Inertial Measurement Unit) and a specialized VPU (Visual Processing Unit) Intel Movidius Myriad 2 as a central calculator.

On this hardware base, a set of algorithms called Intel V-SLAM (Visual Inertial Odometry Simultaneous Localization and Mapping, simultaneous localization and mapping based on visual inertial odometry) is implemented. Its essence is orientation on the ground using only pictures from cameras and data from an inertial sensor with simultaneous mapping of the surroundings. All algorithms are executed locally on the VPU, thus increasing accuracy, minimizing delays in receiving data and achieving high energy efficiency. In numbers, these achievements are as follows: the positioning error during the passage of the closed loop is less than 1%, the delay between the movement and its display is not more than 6 ms. Such indicators will be sufficient even for demanding AR / VR applications. As for consumption,



Distinguished by the principle of operation, T265 is part of Intel RealSense and can work together with other cameras of the family, which are now called Intel RealSense Depth Camera for clarity. An infrared filter is installed in front of the T265 lenses, cutting off the infrared radiation of the D400 cameras, which they use to form a depth map. Thus, the developer has the opportunity to take advantage of both types of cameras in one device.

Dimensions Intel RealSense Tracking Camera T265 - 108 x 24.5 x 12.5 mm, weight - only 55 g. For ease of attachment to moving platforms, a socket for two M3 screws is provided. The camera is available for pre-order at a price of $ 199.
