Abstract
The above measurement device acquires a distance from a vehicle to a partial area of a feature and an angle formed by a direction of viewing the partial area from the vehicle and a traveling direction of the vehicle, for a first area and a second area, the first area being the partial area at a first time, the second area being the partial area different from the first area at a second time. Also, the measurement device acquires length information including a width of the feature. Then, the measurement device calculates a speed of the vehicle from the first time to the second time based on acquisition results by the first acquisition unit and the second acquisition unit. Thus, the speed of the vehicle may be calculated by a scan of a feature in one period.
Claims7
A measurement device comprising:
- a first acquisition unit configured to acquire a distance from a vehicle to a partial area of a feature and an angle formed by a direction of viewing the partial area from the vehicle and a traveling direction of the vehicle, for a first area and a second area, the first area being the partial area at a first time, the second area being the partial area different from the first area at a second time;
- a second acquisition unit configured to acquire length information including a width of the feature;
- and
- a speed calculation unit configured to calculate a speed of the vehicle from the first time to the second time based on acquisition results by the first acquisition unit and the second acquisition unit.
A measurement method executed by a measurement device comprising:
- a first acquisition process of acquiring a distance from a vehicle to a partial area of a feature and an angle formed by a direction of viewing the partial area from the vehicle and a traveling direction of the vehicle, for a first area and a second area, the first area being the partial area at a first time, the second area being the partial area different from the first area at a second time;
- a second acquisition process of acquiring length information including a width of the feature;
- and
- a speed calculation process of calculating a speed of the vehicle from the first time to the second time based on acquisition results by the first acquisition process and the second acquisition process.
A non-transitory computer-readable medium storing a program executed by a computer in a measurement device, the program causing the computer to function as:
- a first acquisition unit configured to acquire a distance from a vehicle to a partial area of a feature and an angle formed by a direction of viewing the partial area from the vehicle and a traveling direction of the vehicle, for a first area and a second area, the first area being the partial area at a first time, the second area being the partial area different from the first area at a second time;
- a second acquisition unit configured to acquire length information including a width of the feature;
- and
- a speed calculation unit configured to calculate a speed of the vehicle from the first time to the second time based on acquisition results by the first acquisition unit and the second acquisition unit.
