Description

TECHNICAL FIELD

[0001] The utility model relates to camera equipment technical field especially, a kind of modular camera and modular camera array. BACKGROUND

[0002] In the field of optical camera structure, matrix camera usually adopts multi-lens combination structure to realize wide-angle imaging, and is usually installed at a high position. In the prior art, such camera mainly faces two problems: first, under high installation environment, affected by vibration, deformation and other factors, the traditional rigid connection structure is difficult to continuously guarantee the alignment accuracy and overall stability between lens units, thereby affecting the imaging quality and equipment life; second, when individual lens performance declines or fails, the entire device often needs to be disassembled and repaired, the operation space is limited and the process is cumbersome, not only low in efficiency, but also easy to cause secondary installation error or component damage due to frequent disassembly and assembly.

[0003] For example, Chinese patent CN110536055A discloses a camera using a multi-lens module, which improves the flexibility of lens replacement to a certain extent through a detachable lens module design. However, the module mounting structure is difficult to maintain stable alignment accuracy for a long time under high-vibration environment, and lacks overall structural stability design for high installation conditions.

[0005] Therefore, there is an urgent need for a modular camera and a modular camera array that can balance structural stability and on-site quick disassembly function under high installation conditions, to effectively improve the reliability and maintenance convenience of the system.
