Camera order

[rprueckl]

Hi,

in Motive there is the option to sort the cameras according to their serial number instead of the 'arbitrary' ordering.
Is something like this also possible via the Camera SDK? I have found the function

Code: Select all

SuggestCameraIDOrder

which could bethe right direction, but I do not know how to use it.

many thanks for your advice,
robert

Hi Robert,

You are correct. The Camera ID of a camera is primarily a human readable number that can be displayed on the camera and/or in your software and UI. For USB cameras, their Camera ID is fixed based on it's physical connection. Now for Ethernet cameras, the Camera ID is 'arbitrarily' assigned as you suggest.

If you want to have your Ethernet cameras report Camera ID's in a certain order, create a list of camera serial numbers and pass it to SuggestCameraIDOrder. Following the call to SuggestCameraIDOrder, you should be able to call CameraID() on your cameras and those Camera IDs will reflect the order you suggested in your call to SuggestCameraIDOrder.

Thanks,
Doug

Hi Doug,

many thanks for the advice. I will give that a try as soon as I get back to the cameras and report back here.

Hi again,

I tried your suggestion and it worked so far. However, it did not influence the order in which

Code: Select all

CameraLibrary::CameraList list

delivers the cameras or the order of frames coming in from the cameras.

Due to that, I decided to manage a separate list of serial numbers in the desired order to manage the cameras and influence the frames of the cameras.

Thanks,
Robert

Excuse me, where is the SuggesttCameraIDOrder method called? I encountered a problem. In the Motive software, what rules are used to sort the sequence numbers of cameraID (by location)?
I tried it and found that the value obtained by CameraID (by serial number) is the same as the value obtained by the CameraID() method through the camera SDK, but I don't know how the CameraID (by location) was obtained?
