Question

What is tracking?

(a) Obtaining coordinates of a particular object in an image

(b) Obtaining a path followed by a moving object

(c) Obtaining the coordinate data necessary to position the sensing system along defined patterns

(d) Obtaining the coordinates of a frame that is captured

I got this question in class test.

My enquiry is from Circular Scanning topic in section Machine Vision Systems of Engineering Metrology

Answer 1

The correct option is (c) Obtaining the coordinate data necessary to position the sensing system along defined patterns

For explanation: Tracking and cylindrical bore or other defect inspections are the applications of circular scanning. In circular scanning, tracking means obtaining the coordinate data necessary to position the sensing system along defined patterns.
