Hi there,

My team and I have tried to calculate the distance to vision target of this year (2020).

We are using Limelight 2 and in their documentation, we found this formula:

https://docs.limelightvision.io/en/latest/cs_estimating_distance.html#using-a-fixed-angle-camera

We found that this formula is pretty accurate when the camera is located in front of the target. However, when the camera positioned from the sides and there is an angle between the camera and the target - the result isn’t accurate.

We also tried to do a linear regression, but we can’t find any segment that remains the same when rotating the camera, its because of the mounting angle of the camera. In 2019 our camera was vertical to the floor and the height of the target remained the same in different angles with the same distance, and we did the regression on that.

We thought maybe the average of the sides’ length will remain the same because when you change the angle, one side increases and the other decreases.

Do you have any solutions? How did you do your vision?

Thank you.
