Provided is a measurement device capable of detecting the occurrence of an abnormality related to a measurement unit. The device is provided with the following parts: a plurality of measurement units provided in a moving body, wherein the measurement units are are used for generating a gate signal, transmitting light for illuminating a stationary structure disposed along a movement path of the moving body in response to the gate signal, and imaging reflected light from the stationary structure, so as to acquire the reflected light from the imaging surface at an exposure time defined by the gate signal, convert an optical signal based on the acquired reflected light into an electrical signal, process the converted electrical signal as an image, and calculate information relating to the movement of the moving body from the processed image; and a determination unit that performs a comparison process on the information pertaining to the movement of the moving body output from each of the plurality of measurement units, and determines an abnormality pertaining to the plurality of measurement units on the basis of the result of the comparison process.
提供一种能够检测测量部所涉及的异常的产生的测量装置。设置以下部件,即,设置于移动体的多个测量部,产生栅极信号,响应于栅极信号而发送对沿着移动体的移动通道配置的静止构造物进行照明的光,将来自静止构造物的反射光成像,以由栅极信号规定的曝光时间将成像的反射光获取到摄像面,将基于获取的反射光的光信号变换为电信号,将变换后的电信号作为图像进行处理,根据处理后的图像计算出移动体的移动所涉及的信息;以及判定部,对从多个测量部各自输出的移动体的移动所涉及的信息进行比较处理,基于比较处理的结果,判定多个测量部所涉及的异常。
