  • Patent number: 9383221
    Abstract: According to an embodiment, a measuring device includes a measuring unit, a capturing unit, an estimation unit, a calculator, and a detector. The estimation unit estimates, for each irradiated point, an estimated projection position on the image, using a direction and a distance of the irradiated point and calibration information based on calibration of a measuring unit and a capturing unit. The calculator calculates, for each irradiated point, an amount of change in reflection intensity and obtains a reflection intensity change point. The calculator calculates, for each estimated projection position, an amount of change in brightness and obtains a brightness change point. The detector detects a calibration shift between the measuring unit and the capturing unit by comparing the reflection intensity change point and the brightness change point.
