Lidar

github neural
https://github.com/UMich-BipedLab/LiDARTag LiDAR-based markers can be used in tandem with camera-based markers to address the issue of images being sensitive to ambient lighting. LiDARTags have been successfully applied to LiDAR-camera extrinsic calibration (paper, GitHub). This figure shows a visualization of LiDARTags of two different sizes in a full point cloud scan. This system runs in real-time (over 100 Hz) while handling a full scan of the point cloud; it achieves millimeter accuracy in translation and a few degrees of error in rotation. The tag decoding accuracy is 99.7%. Uses tbb and nlopt

https://github.com/fangchangma/self-supervised-depth-completion This repo is the PyTorch implementation of our ICRA'19 paper on "Self-supervised Sparse-to-Dense: Self-supervised Depth Completion from LiDAR and Monocular Camera", developed by Fangchang Ma, Guilherme Venturelli Cavalheiro, and Sertac Karaman at MIT. A video demonstration is available on YouTube.

ToF
https://github.com/simondlevy/VL53L5 (forked by bitbank2 Arduino_code) for st vl53l5cx,(stm video) Time of Flight Fast and accurate multizone distance ranging sensor. Multizone ranging output with either 4x4 or 8x8 separate zones. Autonomous Low-power mode with interrupt programmable threshold to wake up the host Up to 400 cm ranging. Multitarget detection and distance measurement in each zone. 60 Hz frame rate capability. Histogram processing and algorithmic compensation minimizes or removes impact of cover glass crosstalk. Motion indicator for each zone to show if targets have moved and how they have moved. Unlike conventional IR sensors, the VL53L5CX uses ST's latest generation, direct ToF technology which allows absolute distance measurement whatever the target color and reflectance. It provides accurate ranging up to 400 cm and can work at fast speeds (60 Hz), which makes it the fastest, multizone, miniature ToF sensor on the market.

Osram
http://diydrones.com/profiles/blogs/osram-s-laser-chip-for-lidar The overall lidar system covers 120 degrees in the horizontal plane, with 0.1 degree of resolution, and 20 degrees in the vertical plane, with 0.5 degree of resolution. In the light of day, it should detect cars from at least 200 meters away, and pedestrians at 70 meters out. This is a very significant breakthrough, it is exactly what is needed to permit all kinds of autonomous vehicle and robot operation in our complex environment. We have primarily been doing autonomous operations with the absolute position control of GPS which does not take into account at all surrounding obstacles, but only provides a position on the surface of the Earth.

Lidar
http://diydrones.com/profiles/blogs/terrain-following-missions-using-lidar#comments The upcoming Copter-3.4 release will include terrain following support for mission commands using either Google earth altitude data or a Laser Range Finder. This is a demonstration video shot at a ski hill near my home in Karuizawa Japan of this new feature.

For this test I used a venerable 3DR IRIS with a PulsedLight Lidar Lite. This lidar is difficult to find but actually I recommend the sensors from Lightware (like the SF10) which, although they are quite a bit more expensive, are much more reliable and offer a greater range.
