Method for rapidly acquiring object three-dimensional form

The invention relates to a method for quickly acquiring the three-dimensional shape of an object. A color multi-stripe mode structured light is projected on an object by a projector, the stripes are led to move a distance in the scene and the distance is more than the width of a sub-stripe. A camera is used for photographing an image sequence simultaneously and according to the deformation of the stripes on the object and relativity of time, and the three-dimensional shape of the object is calculated. The method for acquiring the three-dimensional shape includes the following specific steps of: step A: generating color multi-stripe projection mode; step B: projecting the generated color multiple stripes on the surface of the object by the projector; step C: calculating the time in which an edge template passes through each pixel; and step D: calculating the three-dimensional coordinate of each pixel. The quick and high-precision method provided by the invention for acquiring the three-dimensional shape can ca
