Problems solved by technology

[0004] With the improvement of lens processing technology and the improvement of optical material performance, the lens system has been greatly developed, but the resolution level of the existing lens systems and lenses in visible light mode can only meet below 5 million pixels (most of them are under 2 million 10,000 pixels or less) camera requirements; and switching to the infrared mode at night, the confocal performance is very poor, and the actual imaging clarity is worse than the visible light effect
The main reasons for this phenomenon are: the existing lens system adopts a relatively single structure and shape of the lens, lenses of different shapes cannot be well combined, the performance of the optical glass material is relatively backward, and various parameters and imaging conditions cannot be well matched. Matching, the spherical aberration, coma, astigmatism, field curvature, chromatic aberration of magnification, and positional chromatic aberration of the lens system are not well corrected, so that higher optical performance cannot be achieved

Embodiment Construction

[0038] Exemplary embodiments will now be described in detail, examples of which are shown in the drawings, in which the same reference numerals always denote the same components. In this regard, exemplary embodiments may have different forms and should not be construed as being limited to the description herein. Therefore, the exemplary embodiments are described below only by referring to the drawings to explain aspects of the description.

[0039] Such as figure 1 As shown, the embodiment of the present invention provides a camera lens group for a robot for monitoring camera.

[0040] A camera lens group, arranged in sequence along the optical axis O from the object side to the image side, includes: a first lens group G1, a second lens group G2, a stop ST, a third lens group G3, and an image plane IP. The refractive power of the lens group G1 is negative, the refractive power of the second lens group G2 is positive, the refractive power of the third lens group G3 is positive, and...

Abstract

The invention provides a camera shooting lens group of a robot for monitoring camera shooting. Good balance between the light beam effect and the imaging definition can be obtained, and the camera shooting lens group has the advantages of being large in light field and image plane, clear in imaging effect and the like. The invention also provides the robot for remote wireless monitoring. The robot has the excellent camera shooting effect, and observation at various angles and in various directions is achieved through up-and-down and left-and-right movement of the camera shooting lens group.

Description

Technical field [0001] The invention relates to a monitoring camera robot, in particular to a remote wireless monitoring robot with a high-definition wide-angle camera lens group. Background technique [0002] With the improvement of people's living standards and the continuous progress of robot technology, robots are becoming more and more popular in people's lives. Robots can replace humans in work, can serve humans, and bring many conveniences to humans. In particular, robots can be used for monitoring work. When people are away, or where people are inconvenient, the remote wireless monitoring robot has great convenience. [0003] For robots that replace human eyes for monitoring, a very important component is the corresponding camera lens group, and obtaining high-quality imaging and sufficient field of view are universal requirements, and the requirements for imaging pixel quality and field of view will become higher and higher. , This requires the camera lens group to have a...
