Many SR300, One IR light, While Looking at Same Object (i.e., Use Two SR300, And One IR Light)

[LBill]

If I have two SR300 looking at the same object, how can I make one realsense (with Laser Power set to Zero) use the IR light of the other SR300? I tried it, but I cannot see the depth image in of the SR300 that has Laser Power equal zero. Is there a way to do this?

We have applications with 6+ SR300s running to take snapshots of objects. These are mounted overhead and are arranged lineally or in row/cols to cover large areas.

Basically we have each SR300 connected to a NUC i3 with a capture application listening for a "Capture" request on a UDP socket. When the master application sends the request the "odd" cameras take the snapshot, power-off the laser (power=0), then sleep for a predetermined time. The "even" cameras at the same time wake up, wait a small time, start the laser and capture.. then go back to sleep.

By overlapping the times precisely we achieve a less than 100ms capture time. BUT, this would never work for streaming applications! (If you interested look here - http://www.aikencontrols.com/ndepth-3d-scan.html nDepth 3D Scan - AikenControls )

As Marty suggested we have played with external shutters.. and you can do it.. But it's ugly and expensive..

It would be SO NICE if there was some external blanking signal for the laser.. Leave the projector vibrating but have a way just to externally turn off the laser (quickly).

Guess we can dream?

I just wonder what is changing on the D4xx cameras. Does anyone (Intel?) have information to share for those who have products centered around your technologies?
