System and method for nuclear fuel assembly deformation measurement

A system for measuring a spatial displacement relating to at least a part of a nuclear fuel assembly, the system comprising:

• an imaging system comprising:
• i) a frame,
• ii) a first camera attached to the frame and oriented in a first direction, and
• iii) a second camera attached to the frame and oriented in a second direction that is different from the first direction, wherein the frame is dimensioned such that the first camera and second camera are configured to simultaneously capture different faces of the nuclear fuel assembly;
• a memory;
• and
• a processor configured to receive data from said memory, the processor further being configured to:
• obtain a first image data frame, captured using the first camera of the imaging system positioned with the first camera and the second camera at a first longitudinal location between a two ends of the nuclear fuel assembly, said first image data frame comprising information representing a first view of an observed real world scene comprising at least a part of a lateral face of said nuclear fuel assembly, wherein said first image data frame is captured from the first direction;
• generate a set of reference coordinates based on the first image data frame;
• obtain a second image data frame having been captured by the first camera from the first direction and comprising information representing a second view of the observed real world scene comprising at least another part of the lateral face of said nuclear fuel assembly, wherein the first view and the second view are different from one another and wherein the first image data frame and the second image data frame are captured by the first camera at approximately a same distance from the nuclear fuel assembly from a different longitudinal location relative to the nuclear fuel assembly;
• combine at least the first image data frame and the second image data frame to result in a combined image of the lateral face;
• extract measurement data indicative of a spatial displacement relating to at least a part of said nuclear fuel assembly, based on the combined image information from said first image data frame, based on information from the second image data frame, and based on information from said set of reference coordinate;
• and
• control a display to display a visual representation of said measurement data.
