Awesome Lidar

We can always count on Mark Rober to teach us cool things. For this experiment, he wanted to know if the camera-based emergency braking system on his Tesla was as effective as a Luminar LiDAR-based system. The ultimate test was to see if the cars would stop before driving into a Wile E. Coyote-style fake road. He also used LiDAR to map Space Mountain.

Visual artist Alex Le Guillou created these glorious digital sequences of trees using dots to represent their complex, organic shapes. He used LIDAR scans of the Tasmanian forest and digitally manipulated the 3D models to create this incredible footage. Created for the documentary The Giants: The Extraordinary Story of Bob Brown and the Forest.

Engineer James Bruton is always building amazing things in his workshop. He recently got his hands on a LiDAR scanner unit which can enable 3D computer vision and capture navigational data. He used the device to guide a robot that looks for movement all around it, then turns to fire at what it detected. Demo starts at 17:54.
