Description

Technical Field

[0001] The utility model relates to the field of triple cameras, and particularly to a triple camera and an automotive magic carpet system. Background Art

[0002] A triple camera is a camera based on the principle of vision. By simulating the structure and working mode of the human eye, it can obtain depth information and three-dimensional sense in a three-dimensional scene. This depth perception ability enables the dual camera to have broad application prospects in fields such as measurement, positioning, navigation, and recognition; the triple camera can overcome the shortcomings of a single camera that is easily affected by interference such as light, shadow, and reflection, can work stably in a complex environment, and can be configured according to actual needs to achieve adjustment of different parameters such as viewing angles and focal lengths, and has good flexibility.

[0003] Generally, the structure of a triple camera is mainly composed of a lens, a lens base, a housing, etc. The lens is installed and positioned with the housing through the lens base, and its structural strength meets the requirements. However, the product has a large volume and an increased weight, which does not conform to the design specifications of product lightweight and small size.

[0004] Furthermore, the performance of the triple camera depends on the accurate calibration result. Calibration is the step of determining the geometric relationship between cameras. If the calibration is inaccurate, it will lead to errors in depth information. And two of the three cameras in the triple camera need to maintain a relatively stable positional relationship to obtain accurate depth information. However, affected by the assembly error between the lens and the lens base, the assembly error between the lens base and the housing, and the manufacturing errors of each component, it is difficult to ensure the relative positional relationship between the two lenses during the installation of the lens, which may also lead to calibration failure, thus resulting in errors in depth information.

[0005] In addition, since the focal lengths of the three lenses in the triple camera are different and usually the lengths are also different, and during assembly, it is required that the ends of the lenses far from the housing are flush. In the prior art, the installation position of the lens can be adjusted by the thickness of the lens base. If the lens base is cancelled, it is difficult to meet the requirements for the installation position of the lens. Summary of the Utility Model
