Microsoft HD3000 LifeCam How to use?
 

Hey guys, how to use the Microsoft HD3000 Lifecam just to appear the image on labview program, we was using Axis IP P11 and we had a ip to show the image and with the Microsoft How?:confused:

Re: Microsoft HD3000 LifeCam How to use?
 

Using LabVIEW,
1) Plug the camera into either of the roboRIO USB ports
2) Reset the roboRIO (if it is already on) or power the roboRIO
3) Connect the Driver Station laptop to the roboRIO
4) Select USB Camera SW on the default Dashboard

You should get a video stream after the roboRIO finishes booting and the Driver Station makes connection.

The only thing I'll add is that you will also need to run code on the robot so that the Dashboard knows which robot and camera to get images from.

For IP cameras, this isn't strictly necessary, but for USB, there much be robot code running.

Ok, following the steps suggested we were able to get the camera connected to the Dashboard.
However, we don't have any video stream. We can record and play logged files but it still doesn't show any video..

We confirmed that the camera is connected properly and is receiving power.

Did you activate the LabVIEW Vision license on the laptop when you installed the FRC Update? That's one possible reason.

How can i activate the license?

PS: we use C++ as our programming language and eclipse

Re: Microsoft HD3000 LifeCam How to use?
 

Make sure you have a working internet connection when you install the FRC update on the computer where you will be running the Driver Station. When it asks if you want to activate the NI Vision software...say yes. If it asks for a serial number, use the one on your LabVIEW software envelope.

We are trying to get it to work using Java. Does anyone know the Java code for the Microsoft 3000 camera? We are unable to get it to work following the instructions above. thanks

Check out the Simple Vision, Intermediate Vision and 2015 Vision Examples in the Eclipse plugins.

Hi, we've been attempting to use the camera, and when but when we open the Java SmartDashboard, the live stream is not showing. We get a "connection refused" message. Does anyone have any suggestions?

Re: Microsoft HD3000 LifeCam How to use?
 

Look at the samples suggested above. You need to add (a little) code to the robot side to enable the camera server.

Re: Microsoft HD3000 LifeCam How to use?
 

Getting the Microsoft USB camera working isn't that bad, just grab the 4-5 lines of init code in the Java vision sample and stick it in the same object in your code. But don't bother, apparently it's banned at SVR for eating too much WiFi bandwidth and has caused problems at other events.

Ours took down the whole field during a practice match.

Makes you wonder why it was in the KOP...

Re: Microsoft HD3000 LifeCam How to use?
 

What is your code implementation doing that caused a USB device to take down the WiFi? This is a serious question, because it seems you left out 98% of the details that would be pertinant to understanding what happened.

My observation has been that the new FMS has been dealing with many mDNS issues and idiosyncrasies of Microsoft's various ways of making networking not work. That has nothing to do with Microsoft's USB camera.

Re: Microsoft HD3000 LifeCam How to use?
 

At the events I've attended, maybe 20% of the robots have used the LifeCam. The majority used settings that met the bandwidth guidelines. Some didn't initially, but when asked, made adjustments to fit the guidelines and were fine for the event.

But if a robot doesn't observe those standards, if the camera usage keeps ratcheting back up, the FTA can decide to disable the robot or may the camera be removed from the robot.

There are plenty items in the kit with limits on how they can be used. If you have questions on measuring your bandwidth usage, please ask.
