Distance Measurement #27

Open hesamira opened 1 year ago

hesamira commented 1 year ago

Hi,

What is the reference for measuring distance to objects by camera? and how do you estimate it?

Please, help me. Thanks

We didn't measure distance to objects by camera.

Reference is a fixed point, based on which the distance to objects is measured. For example, your reference here can be the camera. Did you consider the camera fixed or moving? Did you calibrate the camera? Do you need to calibrate every time you use the camera or did you just calibrate once?

We follow the standard object detection setup, in which you're given just images without any camera intrinsics. It may be helpful to check out the COCO dataset.
