The invention discloses a miniaturized high-pixel panoramic day and night confocal optical system. The miniaturized high-pixel panoramic day and night confocal optical system comprises a front lens group, a diaphragm, a rear lens group and an image plane, which are sequentially arranged from front to rear along the light incidence direction; the front lens group comprises a first lens, a second lens and a third lens, which are sequentially arranged from front to rear; and the rear lens group comprises a fourth lens, a fifth lens, a sixth lens and a seventh lens, which are sequentially arrangedfrom front to rear. According to the miniaturized high-pixel panoramic day and night confocal optical system in the invention, the drum type thick lens is adopted on the front end of the diaphragm; therefore, compact design of a light path is realized; the length of the optical system is only 20.439 mm; miniaturized requirements of a high-resolution panoramic camera are satisfied; high-resolutionimaging is realized; the focal power is reasonable to distribute; the process realizability is good; and batch production assembly is easily realized.
Description
technical field [0001] The invention relates to the technical field of optical systems, more specifically to a miniaturized high-pixel panoramic day-night confocal optical system. Background technique [0002] Due to the large imaging field of view exceeding 360°×180°, the panoramic optical system can obtain scene images without dead angles, which cannot be achieved by general optical systems or lenses. Therefore, the panoramic optical system has been widely used in security, surveillance, AR / VR and other fields. The panoramic optical system pursues super-large field of view, large relative aperture, and high-resolution performance indicators. Most of the existing optical systems suitable for high-resolution panoramic cameras have defects such as relatively complex structures and large sizes. Contents of the invention [0003] The present invention provides a miniaturized high-pixel panoramic day-night confocal optical system that uses fewer lenses, high imaging resolutio...
