Abstract: Feature points (41, 42, 43) in the heat image (10) of a casting die (1) are extracted and a predetermined geometrical conversion processing is performed on the heat image (10) such that the feature points are superimposed on the reference feature points (61, 62, 63) set in a reference heat image (30) picked up previously to generate a corrected heat image (20). A difference image (40) is generated by superimposing the corrected heat image (20) and the reference heat image (30) such that the corrected feature points (51, 52, 53) in the corrected heat image (20) is superimposed on the corresponding reference feature points (61, 62, 63). With such an arrangement, a highly reliable difference image can be generated even when the imaging field of vision slips off among a plurality of heat images.

Abstract: There is provided a laser energy measuring unit whose laser energy measuring range is widened. The laser energy measuring unit has a filter provided within an optical path of a laser to attenuate energy of the laser, a calculating section for measuring the energy of the laser passing through the filter, and a condenser lens provided on one side of the filter for condensing the laser. The filter has a shading portion for blocking a center part of the laser beam from being transmitted through the filter at a position coincident with the center of the laser. The center part of the laser where its energy is large is cut by the shading portion, and the calculating section measures the part where its energy is not so large. Thereby, it is possible to widen the laser energy measuring range.

Abstract: Aspects of the subject matter described herein relate to reducing error in images obtained from an image-acquiring system. An image-acquiring system may be modeled as light received from a primary path, light received from a secondary path, and light received from all other paths. Light received from the secondary and other paths may cause error in images captured by the image-acquiring system. By compensating for this light, the error may be reduced. Other aspects are described in the specification.
