3D SENSING TECHNOLOGIES

STEREOSCOPIC VISION

This technology is inspired by how the human eyes capture images. Two cameras are placed at slightly offset positions (just like human eyes). The two captured images are then united into one picture. The small differences resulting from the different camera positions create the stereoscopic, i.e. 3D picture.

Assisted stereoscopic vision uses the additional help of a laser projection module projecting dots on the object or scene to help the camera focus more easily.

STRUCTURED LIGHT PATTERN

A light pattern made up of either lines, squares (periodic structures) or dots is projected onto an object or a scene by a laser projection module. A camera mounted triangularly to the projection module then captures the reflected light. The pattern distortion achieved by the triangulation between projection and camera module serves to acquire the 3D coordinates of the object or scene.

 

 

TIME OF FLIGHT

Direct or sinusoidal short light flashes are emitted by a projection module, and then captured by a camera module. The travel time of the light from the emitter to the object and back to the camera is calculated. The measured coordinates then generate a 3D picture.

USE CASES FOR 3D SENSING

Eye Tracking

Scroll smartphone or tablet screen up and down with eye movement — without touching the display.

Gesture Recognition

Command smartphones, tablets, and computers with hand movements.

3D Pictures and Video

Take 3D pictures and videos, measure real world objects, then send them to a 3D printer.

Facial Recognition

Biometric scanning for access control. No need for keys, passwords, etc.

ADAS

PROVIDING PREMIUM VIEWS AND SAFETY FOR DRIVERS AROUND THE WORLD.

LASER MATRIX HEADLIGHTS

ADVANCED LASER HEADLIGHTS ALLOW THE USE OF HIGHBEAMS WITH ONCOMING TRAFFIC.

Head Up Display

Projection of images, such as navigation, on windshield for safer driving.

LiDAR

Laser depth sensing for ADAS and autonomous driving.

Seat and Airbag Adjustments

Measure size of driver and automatically adjust seat and airbag to fit.

Distracted/Fatigued Driver Detection

Monitor eye movements to detect driver fatigue. Warn drivers before an incident occurs.

Touchless Dashboard Control

Monitor eye movements to detect driver fatigue. Warn drivers before an incident occurs.

Vehicle Access Control

Use facial recognition to identify drivers for vehicle access control (instead of keys).

Automatic Door Opener

Avoid door dings by measuring the distance to the car in the next parking spot, and limiting how far doors will open.

3D Video Conferencing

Appear in conferences in 3D instead of 2D. Mask out the background and add your own.

Secured Banking

Replace password for online banking with facial recognition (together with other metrics).

Security Scanning

Scan face, eyes, or entire body for building access control.

Object Detection

Scan moving objects to distinguish between real threats (burglars) and harmless interlopers (pets) to avoid false alarms.

Gesture Recognition

Control devices and computers with hand gestures.

Collision Warning

Scan area around industrial and domestic robots to avoid collisions with other objects.

Content Generation for 3D Printing

Measure real-world objects and send them to a 3D printer.
