Abstract
A distance measuring device includes a light output unit outputting a linear laser beam, a light scanning unit including a mirror that reflects the laser beam from the light output unit while swinging and generating a pattern light on an object, a light detection unit placed in a position equal to or less than 90% of maximum swing amplitude of the mirror, and receiving the light reflected by the mirror and outputting a light reception signal, an imaging unit imaging the pattern light, a measuring unit measuring a distance to the object based on a result of imaging by the imaging unit, and a control unit controlling generation of the pattern light based on the light reception signal.
