Abstract: An optical lens assembly includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens and an eighth lens. The first lens has a convex surface toward an object side of the optical lens assembly and a concave surface toward an imaging side of the optical lens assembly. The first lens, the second lens, the third lens, the fourth lens, the fifth lens, the sixth lens, the seventh lens and the eighth lens are sequentially arranged along an optical axis from the object side to the imaging side.

Abstract: A depth camera capable of measuring the oblique velocity of an object is provided, wherein a depth camera capable of measuring the lateral velocity of an object includes a depth camera body, a first configuration file, and a lateral velocity calculation system. The lateral velocity calculation system includes: first image-processing software for recording a first depth distance at which images are taken of an object and for calculating the number of pixels corresponding to a lateral movement of the object and the duration of the lateral movement; and lateral velocity calculation software for calculating the lateral velocity of the object. The depth camera capable of measuring the oblique velocity of an object allows the lateral/longitudinal/oblique velocity of an object to be measured in real time using image-related techniques.
