Re: Mounting upside down

Mounting Scarlet upside down is not a problem. The only thing to consider is that all data will be rotated. If you are using ROS you could use the IMU's tf frame for rotating the 3D pointcloud according to Scarlet's orientation, or publish a static coordinate transform that matches your mounting ori...

Re: Get temperature

This is not an offical API but just the regular web interface. The script that I posted does the following: 1. It downloads the status page of the web interface (the first page you see when opening the web interface in your browser) 2. Using grep, it searches for the word "temperature" in ...

Re: modify width and height

Yes, this functionality will come with an already planned firmware update, but I can't promise the release date yet.

Re: Get temperature

If you use the default IP then the URL should be
http://192.168.10.10/status

You can try the following script:

Code: Select all

curl http://192.168.10.10/status/ 2>&1 | \
                grep -A1 temperature | grep span | \
                sed -e 's/^ *<td>[^>]*>\([^\ ]*\)\ .*/\1/'

Re: check device connection

getAllParameters() should throw a TransferException if a network connection cannot be established.

Can you check if this exception is thrown in your case? Is it possible that the freeze you observe is caused by some exception handler in your application?

Re: Get temperature

Unfortunately the device temperature is currently not accessible through libvisiontransfer but only through the web interface. Would it be an option for you to automatically query the web interface? This could be done e.g. through curl. We can add this feature to our TODO list.

Re: modify width and height

Some parameters, as the image size, cannot be configured at runtime. A lot of functionality, such as the image rectification, depend on the image size. This is why that parameter cannot be changed on the fly. We are currently working on a firmware update that will significantly expand the parameters...

Re: check device connection

In UDP mode, when the connection is interrupted, libvisiontransfer should automatically re-connect as soon as the device becomes reachable again. No additional steps need to be performed here. To check if a device is still reachable you can use the device enumeration or check the time since the last...

Re: GigaE Support

Hi Miguel, as I wrote, GigE Vision is not supported at the moment, as this would require more than one network interface to work reliably. The option "Network" in the camera selection is for transferring image data with our API or NVCom through the network. Again, this faces the same probl...

Re: GigaE Support

Hi Miguel, The GigE Vision and USB3 Vision protocols are very similar. The problem is the different interfaces. For GigE Vision you would need a device with three ethernet ports, so both cameras can transfer image data without network collisions, and SceneScan can transfer it's processing results al...
