Abstract

A cell phone 3D imaging method and a 3D imaging cell phone are provided. The cell phone contains a photographing module. The method comprises adding a projector on the cell phone and calibrating the internal and external parameters of the photographing module and the projector, enabling the projector to produce a stripe image and project the fringe image onto an object to be photographed by the cell phone; enabling to cell phone to photograph the object to be photographed by the cell phone, obtain the stripe image of the photographed object, obtain the phase information of the photographed object, and acquire the 3D information of the photographed object and display the same on the cell phone. The 3D imaging cell phone further includes a calibration module and a projector for generating the stripe image and projecting the fringe image onto an object to be photographed by the cell phone. A camera (2) is used for photographing and obtaining a stripe image of the photographed object. A main processor obtains the stripe image of the photographed object and retrieves the internal and external parameters of the camera and the projector, obtains the phase information of the photographed object, obtains the 3D information of the photographed object and displays the same on the cell phone.

Description

technical field [0001] The invention relates to an imaging method and an imaging device, in particular to a mobile phone stereo imaging method and a three-dimensional imaging mobile phone. Background technique [0002] Structured light measurement technology has the advantages of non-contact, high precision, and fast measurement speed. It can be used for 3D model reconstruction, detection of size and shape parameters in industrial environments, etc. Quality control, medical plastic surgery and cosmetology, cultural relic protection and many other fields have broad application prospects. [0003] The traditional monocular grating three-dimensional measurement system takes a long time to process when scanning the contour of the object, and the system equipment is complicated and not easy to carry. However, the mobile phone platform is equipped with a camera and can be equipped with a micro-projector, but there is currently no mobile phone The device can take advantage of thes...
