Embodiment Construction

[0024] Referring to the drawings, there is shown a device according to the invention comprising a manually steerable and positionable hand-held device 1 for checking the condition of a windshield 2 . The device 1 comprises a housing 3 housing a CCD camera 4 located at the proximal end of a dark space chamber 5 defined by a peripheral chamber wall 6 . The distal end of the chamber 5 is either open (as shown in the figure) or may include a window transmissive to the illuminating rays. Filters can be placed to limit certain wavelengths of radiation from entering the chamber. The CCD camera 4 is aimed at the field of view at the far end of the chamber 5 .

[0025] Along the periphery of the chamber housing wall 6 and at the far end of the chamber is mounted an annular array 10 of LEDs arranged to output illuminating radiation in the red wavelength region of the visible spectrum. These LEDs introduce illuminating light into the body of the glass and provide a background 'glow' at...

Abstract

The invention relates to an investigation of vehicle glazing panels. A glazing panel investigation system comprising i) a hand held device, including a dark space chamber, an electronic infra-red image capture device positioned toward a proximal end of the dark space chamber, a compressible light seal provided at the distal end of the device to enable the hand held device to be held against the glazing panel in the region of a target zone to be investigated, an annular array of infra-red light emitters positioned peripherally at the distal end of the dark space chamber, ii) a processor to process data related to captured image data from the electronic Infrared image capture device, and iii) an output device in communication with the processor and arranged to produce an output related to the condition of the glazing panel at the target zone.

Description

[0001] This application is a divisional application of the original patent application number 200580021804.9 (international application number: PCT / GB2005 / 002510, filing date: June 27, 2005, invention name: inspection of vehicle glass plates). technical field [0002] The present invention relates to the inspection of vehicle glass panels, and more particularly to assessing the condition or structural integrity of a target glass panel. The present invention has particular but not exclusive application to assessing the extent of damage to windshields having defects such as chips, cracks or dents, and / or the quality of repairs made to such breaks, cracks or dents. Background technique [0003] Depending on the severity, location and nature of the crack or breakage, vehicle glass panels are sometimes repaired rather than replaced. Typically, during the repair process, resin is injected into the defect crack or break and the resin is subsequently cured. The resin is selected su...
