- Abstract:
- In order to overcome the shortcomings of current automatic recognition schemes applied to mechanicalgauges including huge computing quantity,calibration based on multi dial’s images,this paper proposes a rotationcenter acquisition method based on improved Camny edge detection operator,which can acquire rotation center aswell as radius quickly based on single dial image. and designs hough transform algorithm passing by a specifiedpoint based on precondition that dial’s pointer centerline and rotation center locate on same line,which decreasesdetecting time significantly. Design principle and time complexity analysis of algorithms are introduced in detail.Experimental results demonstrate the algorithms stable with low computational complexity,detecting speed is 4 ~5times faster with memory space reduced. All of which verifies algorithms’ possibility in engineering application.
