Generalization of the formula #3

Closed ataftaf closed 4 years ago

ataftaf commented 4 years ago

Hello, Thank you for sharing this project. Sorry, how did you get this formula:? distancei = (2 x 3.14 x 180) ÷ (w + h x 360) x 1000 + 3 I didn't quite understand. Are we supposed to know the real object size ? Please I want to use this formula in my own Android application and I didn't quite understand how? Can you please make it more general? I have to detect the focal length and then what other parameters? Thanks in advance

Hi @ataftaf , Thank you for reaching out! Actually one of our work regarding this explanation is in the queue for a publication, that's why I can't explain further here for now. However, I am adding a few references for your understanding. Hope it will help. And here 1000 is helping to decide the unit of the result. And 3 is just a constant threshold value added to get the measured distance close to the actual distance. I hope, this helps.
