A three-dimensional imaging unit includes a plurality of image pickup devices that image an image and a rotation drive device which rotates the image pickup devices and adjusts optical axes such that reflections of an object to be measured in a space to be measured have a predetermined amount of overlap. An association calculating unit calculates position association information of pixels when a required measurement point is mapped onto a plurality of images. A three-dimensional shape calculating unit calculates a three-dimensional shape of the object to be measured using the position association information and rotational information of the rotation drive device. A three-dimensional shape estimation calculating unit estimates, from the three-dimensional shape, a three-dimensional shape of a region of the object to be measured where the three-dimensional shape is not obtained. A three-dimensional measurement coordinates calculating unit calculates, from an estimation result, three-dimensional coordinates of two distance measurement points designated on the object to be measured. A distance calculating unit calculates a distance between the two points using the three-dimensional coordinates.

A radiation measurement apparatusincludes a visible image acquisition unitthat takes a visible image, a radiation intensity acquisition unitthat measures intensity distribution of radiation incoming from a direction being substantially equal to an image picking up direction of the visible image acquisition unit, and an intensity display unitA that displays an image acquired by overlaying the intensity distribution of radiation, which is represented by using a plurality of colors being allocated to the intensity distribution of radiation on the visible image.

Radiation measurement apparatus

According to an embodiment, a welding target position measuring device comprises: a groove wall welding part detection means for detecting a groove wall welding part based on a result of the calculation performed by a groove shape change amount calculation means; a weld bead end detection means for detecting a weld bead end based on a result of the calculation performed by a groove shape difference amount calculation means; and a welding target position selection means for obtaining a welding pass number of a subsequent pass in a welding information stored in a welding information recording means and selecting a welding target position of the subsequent pass which differs depending on welding positions based on results of the detection of the groove wall welding part and the weld bead end.

Welding target position measurement device

The present invention includes a camera which takes an image of a camera or an inspection target; a device which estimates the movement of the inspection target; a device which generates a high resolution image having a higher resolution than the pixel resolution of a video image taken by the camera from the video image taken by the camera; a device which evaluates the quality of the high resolution image generated by the generation device; and a device which presents an inspector who visually inspects the inspection target with the high resolution image together with the quality evaluation result of the high resolution image. The present invention can improve the reliability of inspection by use of the high resolution image as well as can reduce the inspection time, and further can guarantee the reliability of the inspection using a high resolution image.
