[0002] Currently, known array cameras consist of multiple independent image sensor units, capable of simultaneously acquiring local image information from different perspectives or the same scene. By stitching together the imaging areas of multiple small lenses, a wider field of view than a single camera is formed, similar to the compound eyes of insects or an array of astronomical telescopes. However, existing array imaging devices often use a linear matrix arrangement, resulting in a limited imaging area. Existing lens imaging devices are often exposed to the external environment, and their lifespan gradually decreases over time. Therefore, there is an urgent need for equipment to protect the lenses without interfering with image quality. Especially in different usage environments, it is also necessary to maintain the mobility of the imaging device, facilitating its placement in different locations to meet the needs of various environments.
