Image Based Tracking at Angle

November 12, 2017 - 11:08am #1

Hello

 

I would like to track an image.

 

The user is likely going to have the image laying flat and hold the camera at a 45(ish) degree angle.

The resulting video feed and image based tracker would look like this

 

I am getting poor image target recognition, despite having Camera Device Mode switched to Speed.

Are there any settings I should use to improve image based marker recognition?

Is it worth creating my image based markers to reflect this perspective? 

For example

Thanks

 

Jim

In general, the larger the angle of incidence, I would expect the less likely the image tracking would work well.  Setting Camera Device Mode to Speed probably spends less time and does a poorer comparison.  I would try switching the Camera Device Mode to MODE_OPTIMIZE_QUALITY.  Though, the main problem may be expecting images to be recognized too far from a perspective parallel to the image surface normal.
