Embodiment Construction

[0029] Before describing example embodiments of the present disclosure, an outline of the present disclosure will be described. figure 1 An information processing device according to the present disclosure is schematically shown. The information processing apparatus 10 includes displacement calculation means 11 and motion estimation means 12 .

[0030] Time-series images obtained by capturing images of the measurement object region of the structure supported by the support member are input to the displacement calculation device 11 . The displacement calculation means 11 calculates the three-dimensional displacement of the measurement target region from the time-series images. The motion estimating means 12 estimates the motion of the supporting member in the structure based on the three-dimensional displacement of the measurement target area calculated by the displacement calculating means 11 .

[0031] In the present disclosure, motion of support members in a structure is e...

Abstract

The present invention makes it possible to provide, at a low cost, information with which the soundness of a support member supporting a structure can be determined. This information processing device(10) comprises a displacement calculation means (11) and a movement estimation means (12). The displacement calculation means (11) acquires sequential images by photographing a measurement area of astructure supported by a support member. The displacement calculation means (11) calculates the three-dimensional displacement of the measurement area from the acquired sequential images. The movementestimation means (12) estimates the movement of the support member at the structure on the basis of the three-dimensional displacement of the measurement area.

Description

technical field [0001] The present disclosure relates to an information processing device, system, method, and computer-readable medium, and more particularly, to an information processing device, system, method, and computer-readable medium that can be used to grasp a condition of a subject by using captured images. Background technique [0002] In bridges, girder end members configured as bearings, joints (expansion joints), fixed ends, etc. are places where damage tends to concentrate and thus require proper operation and maintenance. According to the inspection manual, it is necessary to carry out a visual inspection and to determine whether the function of the bearings, joints, etc. is maintained. [0003] When performing visual inspections, workers need to be close to the ends of the girders, and in some cases aerial work vehicles or bridge inspection vehicles are required to bring workers close to the ends of the girders. Thus, there are cost issues to be addressed f...
