Coordinate System of Image Tracker in Unity

Hi,

I was using MaxST Image Tracking in Unity, and wanted to work with the coordinates of the Image trackable. However, I have observed that minimal movement changes causes a big difference in the coordinates. Does the position obtained from the trackable.GetPose() method not follow Unity standards? i.e 1=1 meter. If not, what is the real world equivalent of these coordinates/ what system of measurement does MaxST use? 

Thank you.

Hi,

We use unity standard unit for translation.

If you set your target size as 1 it means 1 meter.

Please check your target size when you upload target image in our Target manager.

Thank you

We are trying to integrate MAXST image target cordinates with ARKit system. Below is our idea.

First scene will have only MAXST which will do image detection and obtain detected cordinated and save it and move to next scene which has only ARKit. Now we are trying to place the Cube in the detected cordinated. We are not successsful in this.

We see that, when we detect the image from same position, the output matrix from MAXST varies. Can you please help us.

Can you please check how the object will be shown when the object has same transform in two scenes?

For mote detail, please place game object to (2, 2, 2) in MaxstAR scene and ARKit scene with no tracking starting and check how they look.
