    • PROBLEM TO BE SOLVED: To reduce an operation shutdown period and save a large amount of costs required for operators of a nuclear power plant by improving the correctness and speed to perform visual inspections.
      SOLUTION: Methods and systems 56 for quantitative image quality assessment of an imaging system, such as an in-vessel visual inspection system, has a target 10, an image capture device 18 and a computer 58. The target includes one or more image features with varying spatial resolutions and predetermined spatial frequencies. The image capture device is configured to capture an image of the target 10. The computer 58 includes a processor, a memory 60, and computer executable instructions. The computer 58 is configured to receive the captured image, prepare one or more intensity profiles across the captured image responsive to the predetermined spatial frequencies, and determine a modulation transfer function responsive to the one or more intensity profiles.

    • PROBLEM TO BE SOLVED: To solve the problem of being obliged to excavate earth and rocks, by taking into consideration up to the periphery of a work expected place, since the situations different between a drawing and a present state occur much, when performing replacing work to a buried pipe. SOLUTION: This invention is a conduit inspection system having a 3-axis accelerometer in a camera head part, and applying and displaying a correction of making a head and a tail coincide so that a pipe inside image photographed by using directional information becomes the same as an arranging state of an actual conduit, by generating the directional information on a moving distance of the camera head part, a divisional moving distance of dividing its moving distance by a change in the jacking direction and its jacking direction, when jacking in the pipe, and also has a conduit drawing making part, and makes a drawing for indicating a three-dimensional conduit form by image processing by using the directional information.
