The Application of Roundness Error Measurement in the Detection of Badminton Appearance
It proposes a new method to detect automatically badminton appearance. First
images of badmintons were collected and processed in a series of steps. Then
by using the method of region-dependent segmentation
based on polar-coordinate
the feature points of binary images were located. Thirdly
the least-square method was adopted for fitting. Finally
the related indices were propounded to assess roundness errors. The experimental results prove that this method is feasible to differentiate badmintons of the C and D grades
making the nontouched on-line measurement possible.
