Intelligent detection method suitable for curved surface

Abstract

The invention discloses an intelligent detection method suitable for a curved surface. The method comprises the following steps: enabling a three-dimensional detection camera to emit a laser surface; moving a three-dimensional detection camera to enable the laser surface of the three-dimensional detection camera to be aligned with the detection part and form a laser line at the detection part; acquiring an image with laser rays; restoring the three-dimensional point cloud of the curved surface to be detected according to the shape and the position of the laser ray in the image; selecting a standard curved surface in a three-dimensional drawing; and comparing the standard curved surface with the detection contour represented by the three-dimensional point cloud. The intelligent detection method suitable for the curved surface has the beneficial effect that automatic detection can be realized by combining laser and vision.

Description

technical field [0001] The application relates to a detection method, in particular to an intelligent detection method suitable for curved surfaces. Background technique [0002] During the production process of pot products, it is necessary to check the fit between the pot body and the formed pot handle. The current factory practice is to make corresponding inspection fixtures for the curved surfaces of each type of pot handle, place the pot handles on the inspection fixtures by hand, and then check whether the curved surfaces fit together to prove that the design requirements are met. [0003] The disadvantage of the current method is that each type of pot handle must be equipped with corresponding inspection tools, which is a very heavy burden for manufacturers of a large number of different product models, both management costs and manufacturing costs are very high, and manual There are also relatively large errors in the detection effect. [0004] Similar problems exi...
