Hello,
I open this topic about the impact of object shadow on data. I have an example that comes up every time the sun is shining.
The bikes turn into a car as soon as the sun casts a shadow on the bikes.
This Monday, April 17: overcast weather and normal traffic
Between 8:00 and 9:00
This Wednesday, April 19: sunny weather and almost all the bikes are transformed into cars.
Between 8:00 and 9:00
B > A direction is forbidden for car, but when it’s sunny, there are a lot of cars…!
I installed polarizing filters but it mostly works for “poor quality” in bright sunshine.
I also installed the reflective boxes.
So do you have methods for:
Limit this effect? (a filter or something?)
Take this anomaly into account in the data analysis?
- Crossing the data with the weather would be an interesting idea, it seems to me that Telraam crossed this information at the start of the project.
- Set an alert when many cars are driving in one forbidden direction (transformation of cyclists into cars)
Does the Telraam S2 make the difference between object and shadow?
Thanks for your feedback !
