Zusammenfassung: | An optical distance measuring device includes: a light source unit; a light receiving unit that includes a plurality of light receiving elements; an addition unit that adds the number of pulse signals; a histogram generation unit that generates a histogram that records the addition value for each time of flight; a peak detection unit that determines a distance value from the time of flight corresponding to the peak; an image generation unit that generates signal intensity image data and distance image data; a low signal intensity element detection unit that detects a low signal intensity element from the elements of the signal intensity image data; and an image correction unit that corrects a distance value recorded in a target element corresponding to the low signal intensity element in accordance with a distance value of at least one other element in the elements of the distance image data. |
