Range finding apparatus |
摘要 |
A range finding apparatus includes; M photoprojectors (M: greater than one) provided in one-to-one correspondence with M range-finding axes radially extending within a virtual plane for forwardly projecting detection light along the range-finding axes; a photodetector spaced apart from the virtual plane and having N light detecting portions (N: greater than one), which serves as common photoelectric conversion means for the M photoprojectors; a range-finding axis switching device for selectively allowing the M photoprojectors to emit light; and a distance determination device for determining a distance to an object on the basis of detection values output from the N light detecting portions.
