Hi-Res 640x480 TOF Camera (with RGB too) - Already?

[Martin Triplett]

I got an email notification...Orbbec now has their first TOF Camera... with a 640x480 resolution.

Their other products are more typical Kinect-like "depth cams" that put out a matrix of dots and measure the displacement to determine depth.  This is effectively a depth cam like the others, but uses TOF instead and does it at 30FPS.  It also returns an RGB image with a much wider FOV and higher resolution.

This sensor is not for me though.  It consumes an insane amount of power (5.8-9.3W), is large, and expensive.  I much prefer the low res TOF arrays that allow for multiple sensors to run on an I2C bus for the obstacle detection and related use cases.  I will stick with my regular depth cam forward for now and wait to see what comes out next.

I do find the sensor interesting if it indicates a trend in future depth cams.  I don't really know the pros/cons of TOF over regular dot projection depth cams.  I would imagine TOF is much better.  Hopefully future versions will get the price/power/size down to reasonable levels.

Thoughts?

Hey All,

A nice little how-it-works of the Sony TOF sensor. Wonder if these

sensors could be spun around like a lidar unit.

Hey All,

Exciting demo of an STMicroelectronics TOF camera sensor. It seems

like a very exciting time for small robots.
