Disabling Laser Projector?

CAike — Fri, 31 Jul 2015 18:22:43 GMT

Is there any method in the SDK to enable/disable the laser projector?

We need to capture from overlapping depth cameras and need a method to prevent corruption.

Thanks in advance for any help or advice!

There isn't a method that does that, but you could try setting the Laser Power to the minimum, which is almost the same as what you want.

Take a look here for more information:

Samontab,

Thanks for the suggestion. I was looking at this exactly in docs.

Once I try it I will let you know the outcome.

An update..

This appears to work!

By reducing the laser power = 0, then laser is effectively disabled. This prevents the corruption of overlapping cameras due to structured light cross-interference...

BUT.. A caution.. Take note that turning off the laser power does NOT stop the camera from trying to acquire depth images, so you must take care to throw away images from the camera if it's laser is disabled.

Using the "Laser Power = 0" method, we are planning to overlap 6 cameras to acquire a large FOV for a measurement application. Keep everyone posted as to any pit falls we find!

Good to hear that it works.

Good to hear that it works.

Are you using multiple host PCs?, or you managed to use multiple cameras in one PC?

Samontab,

We are not using multiple sensors from a single PC.. I think the SDK doesn't support this as yet.

We have implemented as .NET socket application for our nDepth sensor using a NUCi3 CPU running Win8 Embedded. We then send the images and composite/align then using our vision code running on a NUCi7.

These are packaged in an industrial enclosure allowing for external 24VDC power and Ethernet.

Thanks again for the suggestion and help.
