Precise coupling pattern acquisition system for high-pixel mobile phone camera lens

The embodiment of the invention provides a high-pixel mobile phone pick-up lens precision coupling pattern acquisition system, the high-pixel mobile phone pick-up lens is assembled by a to-be-assembled lens, the high-pixel mobile phone pick-up lens comprises an imaging device, the imaging device comprises at least three sub-imaging systems, each sub-imaging system is composed of a sub-imaging lens and an imaging chip, and the sub-imaging lenses are arranged on the imaging device. The at least three sub-imaging systems are used for discretely collecting patterns of different view field points, and the imaging device is arranged on one side of a to-be-assembled lens; the target division pattern is arranged on one side, far away from the imaging device, of the to-be-assembled lens; the lighting device is arranged on one side, far away from the to-be-assembled lens, of the target division pattern; wherein a target division pattern sequentially passes through the to-be-assembled lens and the sub-imaging lens and t
