Paper Abstract

This paper offers a method to inspect the positional accuracy of the geometric factors on the gear wheel frame of the bit drilling well automatically with a photoelectric image. One non-structured light is adopted as an illuminant. Two CCD cameras are installed at an accurate position. The perspective image can be input into a computer, and the parameters of outlines measured object can be found by means of the verge operator. Applying this method of an inverse perspective transformation, the space locations of those points, lines and planes can be determined in the 3D coordinate. According to require the relations of the position between the parameters on the object those values of relations can be calculated through solving space equations. In fact, it is an available way.
