Abstract: A ranging system includes at least two types of a first-type ranging apparatus, a second-type ranging apparatus, and a third-type ranging apparatus. Each of the first-type ranging apparatus and the second-type ranging apparatus includes a ranging device and a scanner. The ranging device includes a light source, a convergent lens, and a receiver. The third-type ranging apparatus includes a ranging device and a scanner. A FOV of the second-type ranging apparatus is smaller than a FOV of the first-type ranging apparatus. A diameter and a focal length of a convergent lens of the second-type ranging apparatus are greater than a diameter and a focal length of a convergent lens of the first-type ranging apparatus, respectively.
