Method for image processing of image data for a two-dimensional display wall with three-dimensional objects

A captured scene captured of a live action scene while a display wall is positioned to be part of the live action scene may be processed. To perform the processing, stereoscopic image data of the live action scene is received, and display wall metadata of the precursor image is determined. Further, a first portion of the stereoscopic image data comprising the stage element in the live action scene is determined based on the stereoscopic image data and the display wall metadata. A second portion of the stereoscopic image data comprising the display wall in the live action scene with the display wall displaying the precursor image is also determined. Thereafter, an image matte for the stereoscopic image data is generated based on the first portion and the second portion.

Method for high-precision true color three-dimensional reconstruction of a mechanical component

A method for high-precision true color three dimensional reconstruction of mechanical component. Firstly performs image acquisition: the left and right high-resolution grayscale cameras are fixed at same height and spaced at certain distance, an optical transmitter fixed between the two grayscale cameras, and low-resolution color camera fixed above optical transmitter, thus images of measured high-precision mechanical component are shot. Then performs image processing: all images are transmitted to a computer, which uses image processing to record surface information of measured high-precision mechanical component in the point cloud by high-precision true color three-dimensional reconstruction, which reflects color texture information of the surface, so as to realize the non-contact high-precision true color three dimensional reconstruction of high-precision mechanical component. The method uses binocular high-precision grayscale cameras instead of binocular color cameras, which broadens the range of capture wavelengths, retains richer texture details of high-precision mechanical component and improves accuracy of measurement.
