The invention provides a distance measurement device. The distance measurement device is provided with: a light projection unit that includes a light emission unit and that performs rotary scanning using projection light; a light reception unit; a distance measurement unit that measures the distance to an object to be measured, on the basis of emission of the projection light and light reception performed by the light reception unit; and an emission control unit that controls the light emission unit, wherein, during one cycle of the rotary scanning, the emission control unit changes the outputlevel of the projection light and the emission interval of the projection light, while keeping the average power of the projection light fixed.

    本发明提供距离测量装置,其具备:投光部,其包括发光部,并进行基于投射光的旋转扫描;受光部;距离计测部,其基于上述投射光的射出和上述受光部的受光,对至计测对象物为止的距离进行计测;以及发光控制部,其控制上述发光部,上述发光控制部进行如下控制:在上述旋转扫描的一个周期内,使上述投射光的平均功率恒定,并使上述投射光的输出电平及上述投射光的发光间隔变化。
