| Abstract: | The aim of this study is to determine the focusing position of camera relative to the measured point by monocular vision algorithm, and a new monocular vision algorithm is presented. The methods of position from defocus and position from focus in monocular vision method are combined to determine the focusing position. A new kind of energy spectrum entropy image focus criteria function and the calculation model of position from defocus method and position from focus method are given. The verification experimental results indicate the stability and reliability of the proposed algorithm. |
