In addition, two parts were combined into one. The biggest cut in print time comes from the fact that we no longer need support material on the lateral overhangs. Mechanical Update 3.1 introduces a simplified optics assembly, designated #130-000, that cuts print time in half (as well as being much sturdier). Rotating and scaling your structure using simple hand gestures - courtesy of the Leap Motion 3D Controller.This is part of a series of instructional videos f. Check out our GitHub project for instructions on the calibration process.īuilding on feedback from the developer community, we’ve made the assembly easier and faster to put together. This means that auto-calibration can find best possible image quality within a few minutes. The optimization algorithm finds the best distortion parameters automatically by comparing images inside the headset with a known reference. With the North Star calibrator, we’ve automated this step using two visible-light stereo cameras. We have to compensate for this in software to produce a convergent image that minimizes eye strain.īefore we designed the calibration stand, each headset would need to have its screen positions and orientations manually compensated for in software. Introducing the Calibration RigĪs we discussed in our post on the North Star calibration system, small variations in the headset’s optical components affect the alignment of the left- and right-eye images. ![]() Thanks to feedback from the developer community, we’ve focused on lower part counts, minimizing support material, and reducing the barriers to entry as much as possible. Since our last major release, we’ve streamlined Project North Star even further, including improvements to the calibration system and a simplified optics assembly that 3D prints in half the time. ![]() The future of open source augmented reality just got easier to build.
