Abstract

An apparatus for the optical detection of inner walls includes at least one camera, an optical imaging arrangement, and an illumination arrangement. The apparatus is configured to record in a panoramic view by means of the camera a plurality of regions of an inner wall which are axially offset from one another. The apparatus is distinguished by virtue of the illumination arrangement having at least two different functional states, wherein a first brightness distribution emitted by the illumination arrangement is assigned to a first functional state, the brightness distribution differing from a second brightness distribution in at least one second functional state.

Abstract

An apparatus (1) for the optical detection of inner walls (7) is proposed, comprising – at least one camera (K), – an optical imaging arrangement (3), and – an illumination arrangement (5), wherein – the apparatus (1) is configured to record in a panoramic view by means of the camera (K) a plurality of regions of an inner wall (7) which are axially offset from one another. The apparatus (1) is distinguished by virtue of the illumination arrangement (5) having at least two different functional states, wherein a first brightness distribution emitted by the illumination arrangement (5) is assigned to a first functional state, said brightness distribution differing from a second brightness distribution in at least one second functional state.

Abstract

The invention relates to a method for optical shape recognition and/or examination of an object (G) having the following steps: arranging at least one camera (K), at least one linear illumination element (B1, B2) and an object (G) relative to one another in such a way that an object surface (3) can be illuminated by the at least one illumination element and can be recorded by the camera (K); effecting a relative movement at least between two elements selected from a group consisting of the object (G), the at least one illumination element (B1, B2) and the camera (K), wherein a direction of movement encloses an angle different from 0° with the at least one illumination element (B1, B2); recording an image sequence (11) of the object surface (3) with the camera (K) during the relative movement, wherein the surface (3) of the object is imaged in an image plane of the camera (K); illuminating the surface (3) of the object during the lighting of the image plane with the at least one illumination element (B1, B2), and evaluating the recorded image sequence (11) with regard to local surface inclinations and/or local optical characteristics of the object surface (3).

Abstract

A device is provided for optically measuring shapes and/or examining objects, comprising at least one camera, at least one lens, a scattering body and at least two light sources. The device is characterized in that the scattering body is opaque and that at least two light sources are disposed on the inside of the scattering body and illuminate the inside thereof, and that either only two light sources are used, which are disposed opposite from one another on an imaginary diameter line, or that the light sources are disposed at the corners of a—preferably equilateral—triangle or a cross.
