Abstract: Provided is an image encoding apparatus capable of encoding a region important to a user with high quality. An update interval index calculation unit calculates an update interval index representing an index having a long update interval in an entire update tile overlapping the update region for each update region. An importance region specification unit specifies an important region, from each update region by using the update interval index. An quality control unit allocates a code amount, which is larger than a result obtained by dividing the total target code amount per one frame proportionally according to a ratio of an area of an entire important region with respect to an area of an entire update region, as a target code amount of the entire important region and specifies a quality value of the entire important region on the basis of the target code amount.

Abstract: A displacement and weight association apparatus includes a setting unit, a detecting unit, a measuring unit, and an associating unit. The setting unit sets a processing target period. The detecting unit detects weights of a plurality of vehicles having passed a structure during the processing target period. The measuring unit measures a plurality of peak values of displacement of the structure during the processing target period. The associating unit associates the peak values with the weights of the vehicles based on a magnitude relation of the measured peak values and a magnitude relation of the detected weights of the vehicles.

Abstract: A structure displacement amount measurement apparatus includes: an acquiring unit configured to acquire a displacement amount caused on a structure by a weight of a vehicle traveling on the structure along a time series; an estimating unit configured to estimate a section in which displacement is caused based on time-series data of the displacement amount; a detecting unit configured to detect a feature value of change in displacement amount within the estimated section; a determining unit configured to determine whether or not the estimated section is a section of displacement due to a weight of a single vehicle based on the detected feature value; and an extracting unit configured to extract a displacement amount from the time-series data within a section of displacement due to a weight of a single vehicle based on a result of the determination.

Abstract: A photographing guide device includes a detection means and an output means. The detection means compares a candidate image of a structure captured from a capturing candidate position in a capturing candidate direction with a registered image of the structure captured from a given capturing position in a given capturing direction and stored in advance, thereby detecting a positional difference between the capturing candidate position and the given capturing position. The output means outputs information indicating the detected positional difference.

Abstract: A defect detecting device 10 includes an overall displacement measurement unit 11 that measures, based on observation data output from an observation device that observes a target object, a displacement of an overall movement of the target object relative to an observation point at set time intervals, as an overall displacement; a specific period detection unit 12 that detects a specific period in which the measured overall displacement is in a specific state within a period in which observation is performed; a partial displacement measurement unit 13 that measures, displacements at a plurality of points set on the target object in the detected specific period, as partial displacements; and a defect detection unit 14 that detects a defect in the target object, based on the acquired at least one of the temporal changes and the spatial distributions of the partial displacements.
