AI Technical Summary
Technical Problem
The prior art is difficult to effectively distinguish road surface damage from non-damage, resulting in mis-detection and missed detection problems.
Method used
The physical quantity detection unit is used to detect the physical quantity of the vehicle's behavior, and the changes in the physical quantity per unit time are calculated through the arithmetic aggregation unit, and noise is removed in combination with filtering technology to detect road surface damage.
Benefits of technology
Through the filtered data, it can effectively distinguish road surface damage from non-damage, reduce misdetecting, and improve the accuracy of damage detection.

Abstract
To obtain a road surface damage detection device, road surface damage detection method, and road surface damage detection program capable of appropriately detecting road damage.SOLUTION: A calculation server 10 totals section average fluctuations being average values of a plurality of vehicles 200 in the plurality of maximum values of the vehicles 200 in a first predetermined period concerning the fluctuation per unit time in a physical amount indicating a behavior of each one of the detected vehicles 200, and also totals maximum section fluctuations being the maximum values of the plurality of the maximum values in the first predetermined period, in a second predetermined period longer than the first predetermined period. Then, the server detects a road surface damage place based on a result obtained by removing a noise component from the calculation result.SELECTED DRAWING: Figure 1
