That's almost right. Tracker is unitless except for degrees/radians and also time is assumed to be in seconds. But mass and distance units are up to the user... Doug
If a Tracker tab is never calibrated then by default the units are really image pixels.
However, you can use any length and mass units you want. Defaults are m and kg. You can change units by choosing the menu item Coordinate System|Units. You can also choose to show angles in radians or degrees.
Hello Douglas, I wonder one thing in terms of point mass. So, when we chosee the point mass, a mass unit section appears on the interface. It shows default mass value 1.000kg. So, is this section for the mass of the moving object in the video? For example, we will track a car and we need to enter the weight of the car into this section, right?
Yes, you should enter the actual mass of the object being tracked.
