Abstract: PROBLEM TO BE SOLVED: To identify a welding error surely by recording and evaluating the side observation of a seam additionally using a method for observing and evaluating a welding seam from above. SOLUTION: Thin plates 6, 7 are welded at a seam 26 where a camera 23 and a line projector 24 are disposed above. Furthermore, a camera 25 is disposed while inclining at an angle of 45 deg. against the plane of the thin plate, for example, so that the seam 26 can be observed from the side. Images from two cameras 23, 25 are evaluated by an evaluation unit 27. In this regard, two images of the seam 26 can be combined electronically into one image and evaluated. The observation angle α can be selected differently from 45 deg., e.g. in the range of 0-85 deg.. The cameras 23, 25 advantageously observe same part of the seam 26, i.e., a same projection line.

Abstract: The inspection system provides a number of optical images of the bottle mouth, directed onto at least one image detector, with subsequent image evaluation for acceptance or rejection of the inspected bottle. Pref. a mirror device (6) with a number of planar mirrors (9) is used for providing the optical images of the bottle mouth, received by the CCD image sensor of a video camera (5). The images are selected so that together they provide a 360 degree view of the bottle mouth.

Abstract: According to the method according to the invention, the optical inspection of a transparent article (3), in particular the optical inspection of a concave container bottom, the article (3) being positioned between a radiation source (1) and an image-acquisition device (2) and an image of the article being acquired and processed, is improved in that at least one optical correction element (7.1) is interposed in the beam path between the radiation source (1) and the image-acquisition device (2), which correction element corrects the beam paths which lead to undesired dark or black points on the image such that such dark or black points are prevented or brightened, so that an image which is satisfactory for image analysis is produced.

Abstract: The checking method uses an optical light beam directed along a line extending across the weld seam (26) between a pair of abutting plate edges, with evaluation of the image of the weld seam obtained from above via a camera. An additional sidewards view of the weld seam is provided by a second camera and the 2 images are evaluated individually or in common.

Abstract: In the welding together of sheet-metal blanks (6,7) an image of a line pattern projected across the weld seam is captured by a camera (31) and evaluated to inspect the weld seam. For improved inspection, a sidewards view of the weld seam (26) is obtained, eg. by means of a prism (30), in addition to the view from above. This affords an improved and more accurate inspection of the weld seam.
