The present invention discloses a method and device for identification of a blurred screen image. The method considers the blurred screen image feature: having repeated content, and the method comprises: determining whether the content of a single image has periodicity or not, if the content of the single image has periodicity, determining that the single image has the blurred screen image feature, and determining that the single image is a blurred screen image. The method employs a single image to complete the identification of whether the single image is the blurred screen image or not, and is convenient and rapid.

Method and device for identification of blurred screen image

A method for reducing a moire fringe includes calculating a moire fringe width for each of different angles between a microlens array and pixels of a display screen. The method includes determining, to be a final inclination angle between the microlens array and the pixels of the display screen, one of the different inclination angles that corresponds to a minimum width among the calculated moire fringe widths.

Three-dimensional reconstruction method based on coding structured light

The invention discloses an imaging method of a three-dimensional measuring system, which solves the imaging problem of obtaining a three-dimensional curve surface figure through a two-dimensional digital image and adopts the technical proposal that an external light source forms stripes with black and white intervals on the surface of an object to be measured through a glass grating, two video cameras that take a certain included angle between the left and the right simultaneously collect left and right two-dimensional digital images of the object to be measured that has the stripes with black and white intervals on the surface, and further collect the left and right two-dimensional digital images when stripes are formed on the surface of the object to be measured with different glass gratings and different grating positions, and according to the polar line constraint theory, pixels on the black stripes in the left two-dimensional digital image can be found, thus determining a polar line and matching points in the right two-dimensional digital image, and a computer center can compute world three-dimensional coordinates of the spatial points through position coordinates of the left pixels and position coordinates of the right matching points, combine all the spatial points, and obtain the three-dimensional curve surface figure of the object to be measured The imaging method of the three-dimensional measuring system has the advantages of using simple devices, low cost, quick imaging speed and high measurement precision
