I am using the marker tracker available from maxst, but I am having problems with the dimensions of the markers, when I use the marker group behavior file, I set the marker size, which in this case should be 25 cm (placed 0.25 mm), being use maxst markers with a size of 25 cm by 25 cm and with a resolution 640X480. After performing several consecutive tests, performing a linear route of 3 m, it appreciates an error of about 20 cm per m. What can I do to solve the problem?


Thank you kindly for your attention.

Does the actual size of the marker mean 25 cm by 25 cm? What does placed 0.25mm mean? Does a 3m linear path mean you walked 3m? So does that mean that the content was created 20cm away from the marker's position?

Yes, the actual size of the marker is 25 cm by 25 cm. Yes I walked 3m, linearly. My goal is not to create content over the marker, but to know how far the marker is from the camera. This distance is that has an error of 20 cm per m.

The SDK we provide does not have camera calibration. Therefore, the size obtained through the SDK is not the actual size. You want to get the actual size of how far you are from the marker, but it is impossible to get the actual size.
