Abstract

The invention discloses a curved surface normal measuring device and a curved surface normal measuring method, wherein the curved surface normal measuring device comprises: a laser for emitting at least one cross laser line; The camera module of the image; the control processing module connected with the laser and the camera module respectively; wherein, the control processing module is used to: obtain the image of the measured curved surface irradiated by the laser through the camera module, on the projection plane of the laser and on the camera On the image plane of the module, the cross laser line is analyzed through visual geometry, and the normal direction of the intersection point of the cross laser line on the measured surface is realized. The technical solution provided by the invention can effectively realize the automatic measurement of the normal direction of the curved surface and improve the accuracy of the normal direction measurement of the curved surface.

Description

technical field [0001] The invention relates to the technical field of measurement and detection, in particular to a device for measuring the normal direction of a curved surface and a method for measuring the normal direction of a curved surface. Background technique [0002] During the automatic processing and assembly of curved surface parts, the processing head needs to perform operations such as drilling or riveting in the normal direction of the curved surface. Therefore, the normal direction of the curved surface needs to be adjusted before the automatic processing of the curved surface parts, so that the processing feed direction coincides with the normal direction of the processing point. The accuracy of the normal adjustment has a great influence on the processing quality and the service life of the product. Therefore, the efficient and stable normal measurement adjustment method and equipment can improve the quality and efficiency of automatic processing of curve...
