Facial image acquisition device for skin analysis

Abstract

The invention discloses a facial image acquisition device for skin analysis. The device comprises a photomask, light sources, an imaging lens and a locator, wherein the photomask is symmetric about avertical plane and gradually narrows from the opening to the bottom; the imaging lens is arranged in the center of the bottom of the photomask and used for acquiring a facial image of a user; the light sources are arranged at the bottom of the photomask and symmetric about the imaging lens; the locator is arranged at the opening of the photomask and used for fixing the head of the user, so that points of the face of the user can fall in the focal plane of the imaging lens as many as possible. A proper imaging light path is designed by simulation of heads of Asian people, so that imaging conditions are almost consistent when facial images of users are shot each time, consistency of acquired images is improved during facial acquisition of different users or repeated facial acquisition of thesame user, and skin analysis of different groups or skin condition analysis of tracked unified users is facilitated.

Description

technical field [0001] The invention belongs to the field of skin analysis, and more particularly relates to a facial image acquisition device for skin analysis. Background technique [0002] Skin analysis and skin classification technologies have long served as the foundational technology for personalized skin care. The earliest is by naked eye observation, the skin type is simply divided into dry, normal, oily and mixed. However, this classification method is too rough to provide targeted solutions to skin problems. For example, enlarged pores may be caused by one or more factors such as clogged pores, excessive oil secretion, collagen loss, or dry skin. Yes, but it is simply thought that it is caused by oily skin, and simple or even excessive cleansing of the skin cannot solve the problem of enlarged pores. [0003] As a result, more accurate and objective skin analysis and skin classification technologies emerged as the times require. The mainstream method is to collec...
