the API say
“Returns the translation in unknown units from the camera in the X direction.
This method is useful for determining the apriltag’s location away from the camera. However, the size of the apriltag, the lens you are using, etc. all come into play as to actually determining what the X units are in. For ease of use we recommend you use a lookup table to convert the output of this method to something useful for your application.”
But I don’t understand,so could you give a sample or tell me how do I to Implement it.
