摘要:
A precision machine vision inspection system and method for increased inspection throughput. The vision inspection system includes a movable stage for scanning and measuring selected workpiece features. In prior systems, conventional interspersing of image processing and inspection operations with image acquisition operations required stopping and starting the stage motion during image acquisition, necessitating associated delays or wait-states in various operations. Such delays are avoided in this invention by acquiring images continuously, with a timing that is independent of image inspection operations, so that delays and wait-states are avoided. In addition, continuous stage motion is combined with a strobe lighting feature during the image acquisition operations to acquire blur-free images at a high rate. Improved image acquisition and image analysis routines including these features are created and stored by the system.

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).
摘要:
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.
摘要:
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).
