| Re: [sumo-user] Field of vision filter for context subscription |
Hello Jakob
Thank you for your reply and availability. I keep this procedure for future issues. Indeed I tried the code below and the filter is working successfully:
subscribed = False
if subscribed:
for v in sorted(traci.vehicle.getContextSubscriptionResults(str(rl_id)) or []):
near1.add(v)
if not subscribed:
traci.vehicle.subscribeContext(str(rl_id), traci.constants.CMD_GET_VEHICLE_VARIABLE, 50, [traci.constants.VAR_POSITION])
traci.vehicle.addSubscriptionFilterFieldOfVision(90)
subscribed = True
Best regards,

Similarly there is no update on the initial context.The filters are not working but there are no errors in the execution and I have the correct radius range.Did I miss something?Thank you in advance.Le ven. 8 janv. 2021 à 14:51, Yasmina Jaafra <yasmina.jaafra@xxxxxxxxx> a écrit :Hello,Here attached a doc with the 2 screenshots: Sumo Gui and results.Best regards,Le ven. 8 janv. 2021 à 05:44, Jakob Erdmann <namdre.sumo@xxxxxxxxx> a écrit :the image attachments are missingAm Fr., 8.

Thank you for the reply. I’m using the right methods.
traci.subscribeContext(str(rl_id), tc.CMD_GET_VEHICLE_VARIABLE , 50, [tc.VAR_SPEED, tc.VAR_POSITION])
traci.addSubscriptionFilterFieldOfVision(10)
print(self.k.vehicle.getContextSubscriptionResults(str(rl_id))
Below an invalid example, rl_id is the red car (rl_0):
In both cases (with or without addSubscriptionFilterFieldOfVision(10) function) I have the same result:
Shouldn’t sumo at least ignore the exo vehicles behind the ego ?

I am using context subscription to limit the ego vehicle perception. The application looks fine and I assume that the defined zone is a circular area which center is the ego and radius is the indicated distance argument. I tried to apply a field of vision filter, unfortunately it’s not working. I indicated different opening angles (from 5 to 180), however, the returned result is always the subscription context initial range. I think that the angle would have delimited an area from the circular zone in front of the vehicle. Could you please confirm and check if I set something wrong in the script below.
traci.vehicle.subscribe_context(str(rl_id), tc.CMD_GET_VEHICLE_VARIABLE , 50 , [tc.VAR_SPEED, tc.VAR_POSITION])
traci.vehicle.add_filter_field_vision(40)
print(traci.vehicle.get_context_subscription_results(str(rl_id)))Regards,
