Title:
DEVICE FOR CONTROLLING NON-CONTACT DIGITIZING
Document Type and Number:
WIPO Patent Application WO/1992/013677
Kind Code:
A1
Abstract:
A device for controlling digitization with a high accuracy which realizes the optimum attitude control of a non-contact distance measuring device on the face of a model to be copied. A non-contact distance measuring means (105) samples the coordinate values of plural points on the model face, and the sampled coordinate values are stored in a storage means (101). A point selecting means (102) selects three points from those whose coordinates are stored to form a triangle which is best similar to an equilateral trianlge. From the selected points, a vector calculating means (103) calculates the normal vectors. Using the normal vectors, the attitude of the non-contact distance measuring means (105) is controlled by an attitude controlling means (104).
