Abstract:
A surface inspection apparatus for inspecting a complex shaped surface, such as the paint surface of a motor car, comprising laser means (31) providing a beam (26) of radiation, scanning means (39) for scanning the beam across the surface, retroreflective material being provided to reflect radiation reflected from the surface back along the incident beam path, the apparatus including the retroreflective material being mounted as a unit to be moved over the surface of the motor car by means of a robot (13). Analysis of the light signal will indicate defects such as scratches, paint inclusions, orange peel, dry spray, dents and gloss defects and can distinguish the defects from features which should be present on the surface such as door cracks.
Abstract:
This invention concerns spectroscopy apparatus comprising a light source (101) arranged to generate a light profile (110) on a sample, a photodetector (103) having at least one photodetector element (104) for detecting characteristic light generated from interaction of the sample with light from the light source (101), a support (109) for supporting the sample, the support (109) movable relative to the light profile (110), and a processing unit (121). The processing unit (121) is arranged to associate a spectral value recorded by the photodetector element (104) at a particular time with a point on the sample predicted to have generated the characteristic light recorded by the photodetector element (104) at the particular time based on relative motion anticipated to have occurred between the support (109) and the light profile (110).
Abstract:
A scratch verification method and apparatus (1) for detecting and analyzing defects in a surface is disclosed. The apparatus (1) include a detection device (6) with a plurality of emission sources (7) and a plurality of sensors (8). A processor (9) is connected to the detection device (6) and is configured to apply one or more sets of criteria to one or more corresponding target areas (5) of a surface (2). The processor (9) is further configured to differentiate between data from the one or more target areas (5).
Abstract:
Un appareil de contrôle de surface permet d'inspecter une surface de forme complexe telle que la surface de peinture d'une voiture, et comprend un laser (31) fournissant un faisceau (26) de rayonnement, un organe d'exploration (39) permettant de balayer le faisceau sur la surface, un matériau rétroréfléchissant étant prévu pour réfléchir le long de la trajectoire du faisceau incident le rayonnement réfléchi depuis la surface, l'appareil comportant le matériau rétroréfléchissant étant monté comme une unité à déplacer au-dessus de la surface de la voiture à l'aide d'un robot. L'analyse du signal lumineux révèlera des défauts tels que rayures, inclusion de peinture, peau d'orange, pulvérisation sèche, bosses et défauts de brillants, et permettra de distinguer les défauts des caractéristiques qui doivent être présentes sur la surface telles que des craquelures de portières.

Abstract:
PROBLEM TO BE SOLVED: To provide an image measuring system and its programming method increasing its throughput in image measuring. SOLUTION: In the image measuring system, both 1 set of target positions of a work measuring image including aspect of the work to be measured for an image group and 1 set of image acquisition parameters for each image of the image group for each image are determined, and then an image acquisition routine is determined. A machine control instruction of this image acquisition routine is provided with an operational control instruction and an image acquisition instruction based on at least some of the obtained set of target positions and each set of the determined image acquisition parameters. Additionally, the machine control instruction can be operated so as to execute the machine control instruction for acquiring and storing at least two or more images of the image group, while acquiring and storing at least two or more images of the image group without performing any image measuring operation.

Abstract:
PROBLEM TO BE SOLVED: To provide a mapping measurement apparatus for implementing mapping measurement using a simple apparatus constitution. SOLUTION: The mapping measurement apparatus 10 is provided with a light irradiating means 12 for irradiating a sample with a light and a light detecting means 14 for detecting a light reflected from or transmitted through the sample via an aperture 16, limits the light detected by the light detecting means 14 to the light from a predetermined measured region by leading the light reflected from or transmitted through the sample to the aperture 16, and implements the mapping measurement within a predetermined range of the sample by changing and measuring the measured region. A detecting scan mirror 18 is provided on an optical path from the sample 28 to the aperture 16, and has a reflecting face with a movable orientation. Since the reflecting face of the scan mirror 18 is variable in an incident direction of the reflected light or the transmitted light, the measured region detected by the light detecting means 14 can be changed.
