the inspection device including: a substantially column-shaped first barrel that includes a first through hole configured for an object to pass therethrough; and a plurality of imaging units provided on the inner peripheral surface which forms the first through hole in the first barrel; and the control device including: an image processing unit configured to process an image captured and output by each of the imaging units for the purpose of inspection.

An inspection system for a vehicle includes a vision inspection device including a plurality of vision camera and a plurality of laser device which move along exterior and sides of a door, which will be inspected, and inspect segmented sections respectively, a hanger device clamping the hemmed door on a hanger frame, and a jig device which clamps the hanger frame of the hanger device, and moves the door toward the vision inspection device for the vision inspection device to inspect the door fixed to the hanger device.

Quality control of a periodic structure is performed using the damping rate of acoustic waves generated in the periodic structure. In this technique, an excitation light beam illuminates the first layer in the periodic structure to excite an acoustic wave. Possible irregularities in the periodic structure can scatter the acoustic wave, thereby increasing the damping rate of the acoustic wave. A sequence of probe light beams illuminates the periodic structure to measure the acoustic wave as a function of time to generated a temporal signal representing the damping rate of the acoustic signal. The acquired damping rate is employed to evaluate the quality of the periodic structure.

A processor of the inspection support device acquires an image obtained by imaging a structure to be inspected and detects damage to the structure on the basis of the acquired image. In a case where two or more types of damage (cracking B and linear free lime C.sub.2) to the structure are detected, the processor determines whether or not two or more types of damage are detected from the same or adjacent positions. In a case where determination is made that the cracking B and the linear free lime C.sub.2 are detected from the same or adjacent positions when the processor outputs the damage detection result (a damage image, a damage diagram, and the like), the processor preferentially outputs a damage detection result of the linear free lime C.sub.2 in accordance with a priority of a damage type (FIG. 16A and FIG. 16B).

An installation intended to enable a conformity check of a mechanical part of a vehicle, including at least one magnetizing device, and at least one device for spraying a revealing product, wherein the installation also includes at least one device for generating at least one image by means of at least one image capture apparatus and at least one device for transmitting the at least one image on an analysis unit.

The invention relates to an apparatus (1; 1a; 1b; 1c) and a method for determining a material property of a test specimen (5; 5a; 5b; 5c) in a test specimen region (6; 6a; 6b; 6c) near the surface, said apparatus comprising at least one electromagnetic radiation source (2; 2a; 2b; 2c) for irradiating at least one surface region (4; 4a; 4b; 4c) of the test specimen, and a detection device (8; 8a; 8b; 8c) for detecting thermal radiation (9; 9a; 9b) emitted by the surface region and/or for detecting radiation (31) reflected from the surface region (4; 4a; 4b; 4c) of the test specimen. An evaluation device (13; 13a; 13b; 13c) for ascertaining the material property to be determined on the basis of the emitted thermal radiation (9: 9a: 9b) and/or the reflected radiation (31) is expediently provided. Advantageously, it is possible for the material property to be determined particularly reliably and nondestructively.
