Problems solved by technology

Compared with the passive type, the active image acquisition device can weaken the influence of ambient light conditions through the depth lens and the laser light source, but the detection distance is less than 100 meters, so the detection range is too small to meet the rapid development of intelligent needs

Abstract

The invention provides an optical system, an optical lens, a camera module and a laser projector. The optical system sequentially comprises, from an image side to an object side: a first lens, whereinthe first lens has positive focal power, and the surface, facing the image side, of the first lens is a concave surface; a second lens, wherein the second lens has negative focal power, and the surfaces of the two sides of the second lens are concave surfaces; a third lens, wherein the third lens has positive focal power, two side surfaces of the third lens are convex surfaces, and the curvatureradiuses of the two side surfaces of the third lens are the same; and a fourth lens, wherein the fourth lens has positive focal power, the surfaces of the two sides of the fourth lens are convex surfaces, and the curvature radiuses of the surfaces of the two sides are the same. The optical system provided by the invention can meet the requirements of large-range and high-density detection.

Description

technical field [0001] The present invention relates to the field of optical systems, and further relates to an optical system, an optical lens, a camera module and a laser projector, in particular to a mobile platform that can realize large-scale active detection and obtain area array depth information Optical systems, optical lenses, camera modules and laser projectors. Background technique [0002] The traditional vision system converts the three-dimensional environment into a two-dimensional image, and analyzes the two-dimensional image to obtain environmental information. However, due to the lack of depth information in the two-dimensional image, a complete environmental cognition cannot be obtained by analyzing the two-dimensional image. With the global development of intelligence, the information contained in traditional two-dimensional images can no longer meet the needs of intelligent development, and depth information, as one of the indispensable information for en...
