IMAGE ACQUISITION APPARATUS

WIPO Patent Application WO/2021/253308

A1

The embodiments of the present application disclose an image acquisition apparatus, which can improve the quality of acquired three-dimensional data. The image acquisition apparatus comprises: a micro lens array, comprising a plurality of micro lenses; a plurality of pixel units, corresponding to the plurality of micro lenses on a one-to-one basis, each pixel unit among the plurality of pixel units comprises a first pixel and a second pixel, and each micro lens being used for converging an optical signal returned by an object to the corresponding pixel unit, enabling the same angles of the optical signals received by the plurality of first pixels in the plurality of pixel units, and the same angles of the optical signals received by the plurality of second pixels; and a processing circuit for obtaining a first-viewing-angle image according to an output of the plurality of first pixels, obtaining a second-viewing-angle image according to an output of the plurality of second pixels, obtaining a TOF image of the object according to an output of the plurality of pixel units, and generating target three-dimensional data of the object at least according to the TOF image, the first-viewing-angle image, and the second-viewing-angle image.
