ZhiSensor

They were demonstrating a small Depth Sensor that uses MEMs technology.
They also have a MEMs Structured Light Generator and MEMs Scanning Mirror Module.

Their “MoveSense SKY Pro” is a stereo camera designed for UAVs, but could probably be used for other types of robots.
They also have the “MAKE Pro”, which has a light projector for active stereo, and the “PIONEER” which is a 4-directional stereo camera designed to mount on a UAV.

Guardian Optical Technologies

They were demonstrating a sensor for inside vehicles, designed to detect the presence of people.
It has a 3D sensor (camera) that goes near the dome light in your car and additional IR light projectors above the 4 doors. If you divide the seating area into 2D cells of space, the sensor can detect the presence of a person and measure the distance (depth) in that part of space. Given that the sensor could detect me when I was not moving, my guess is that they’re using either thermal IR or a technique called “video magnification”.

Occipital

They were advertising their Structure Core depth sensor module for OEMs and developers.
They also had the PX-80 3D mapping sensor, which was developed by their recently-acquired company Paracosm.
