hi, i'm try to using the visual tracking gpm tool to detect an object over a pattern belt conveyor? (belt has same some pattern) Is there away to teach the background to be a reference so everytime the object on the conveyor it will find center based on the background? Also is there away to use blob with visual tracking? how do we send origin and angle data to the robot?

There are tools that can cancel out the background if it is repeated. Unfortunately it is only available on 8.3V and up. As for the other with out a 3DL or 3DAS you would have to build a way to get offset for the angle yourself. 2D guidance isn't a good use for it.

Yes, just add a blob tool to your visual tracking vision process and delete the standard GPM.
Quotehow do we send origin and angle data to the robot?
There is an option on the blob tool to calculate the angle. There are two methods to calculate the angle: axis of inertia or minimum rectangle. Traditionally, blobs always found the angle via the axis of inertia method, but the minimum rectangle method was added for "rectangular" or "square" blobs where axis of inertia would be off by 45 degrees.
You may find that the blog tool gives some unusual rotation values... if so, you may want to use a conditional execution tool or two to clamp the angles between +/- 90 or something.

can we simulator the data by using register? so everytime we trigger by the sensor, we send register data to buffer/ queue without using vision. thanks
