Hi,

The release notes of RoboDK 5.0 states: 2D camera simulation now shows cameras as items in the station tree and they are saved with the station
However, I see a few regression bugs to RodoDK 4.x and a few missing features inline with this new behavior

1. Camera item type missing

Code:
import robolink
rdk = robolink.Robolink()
camref = rdk.ItemUserPick(
‘Select the Camera location (reference, tool or object)’)
cam = rdk.Cam2D_Add(camref, ‘FOCAL_LENGHT=6 FOV=32 FAR_LENGHT=1000’)

return: RoboDK item of type 19. Item type 19 is missing from the ITEM_TYPE_XXX constants.

2. Cam2D_Add does not add the Item to the tree
Creating a camera using the API does not behave in the same way as through the Connect – Simulate 2D camera. It is not added to the station tree. See CameraAddTree attachment

3. Settings passed to cam_params does not apply correctly
Using the code above, as per the example of CameraAdd.py, the applied settings differ. See CameraSettings atachment

RoboDK 5.0.0.17599
robodk API 5.0.0

Thank you,

You are right, the API was still using the previous method where cameras don’t have an item linked to it.

This should be fixed with the latest version now. Make sure to update RoboDK and take the latest version of the RoboDK API for Python v5.0.1 from GitHub or PyPi.

Thank you for the follow-up and support. I forced an update of the API to 5.0.1 through

Code:

pip install robodk –force

and updated to RoboDK 5.0.0.17833-2020-07-01
However, sending the following code still causes issue (regression to the behavior in RoboDK 4.x:

Code:

import robolink
rdk = robolink.Robolink()
camref = rdk.ItemUserPick(
‘Select the Camera location (reference, tool or object)’)
cam = rdk.Cam2D_Add(camref, ‘FOCAL_LENGHT=6 FOV=32 FAR_LENGHT=1000’)
It creates 2 camera windows and closing any one of them causes a crash
The camera settings are also still wrong as per the attached screenshot: FOV=32 FAR_LENGHT=1000 gives FOV=48.46 FAR_LENGHT=994

Thank you

You are right,

Also, make sure to update the RoboDK API for Python:

Code:

pip install robodk –upgrade
