Abstract
A load meter includes a detector, a storage unit, and a load calculator. The detector detects, by using a captured image obtained by capturing a road and a vehicle present on the road, a displacement amount in the captured image, the displacement amount corresponding to displacement caused on the road by application of a load of the vehicle. The storage unit stores information indicating a relation between the load and the displacement amount. The load calculator calculates the load based on the displacement amount and the information.
Claims18
A load meter comprising:
- a projector configured to project patterned light onto a road;
- a detector configured to detect, by using a captured image obtained by capturing an area having the patterned light projected onto the road and a vehicle present in the area, a displacement amount of the patterned light in the captured image, the displacement amount corresponding to displacement caused on the road by application of a load of the vehicle;
- a storage unit configured to store information indicating a relation between the load and the displacement amount;
- and
- a load calculator configured to calculate the load based on the displacement amount and the information.
A load measurement method comprising:
- projecting patterned light onto a road;
- detecting with a detector configured to detect an image, by using a captured image obtained by capturing an area having the patterned light projected light onto the road and a vehicle present in the area, a displacement amount of the patterned light in the captured image, the displacement amount corresponding to displacement caused on the road by application of a load of the vehicle;
- and
- calculating with a load calculator the load based on the displacement amount and information, stored in a storage unit, indicating a relation between the load and the displacement amount.
