Embodiment 1

[0037] A new method for collecting and displaying 3D color data in real scenes, such as figure 1 As shown, the fringe is projected onto the surface of the measured object by using a high-speed defocus projector, and the projected pattern of the high-speed defocus projector is defocused. The defocus projection pattern is a binary pattern, and the high-speed color camera is used to receive the high-speed defocus The synchronous signal of the projector simultaneously collects the deformed fringe image modulated by the surface topography of the object, and transmits the collected data to the computer for data collection and processing. The computer processes the image captured by the camera, solves the phase of the stripes in the captured image, and calibrates the entire measurement system to obtain the corresponding relationship between the pixels on the camera and the pixels on the projector, and then pass the decoding algorithm to obtain the object color texture and three-dimen...

Abstract

The invention provides a novel real scene three-dimensional color data acquisition and display method. The novel real scene three-dimensional color data acquisition and display method utilizes a high-speed out-of-focus projector for projecting stripes to the surface of a measured object, and performs out-of-focus operation on a high-speed out-of-focus projector projection pattern; the out-of-focusprojection pattern is a binary image; a high-speed color video camera is used for receiving a synchronous signal of the high-speed defocusing projector, acquiring a deformed stripe image subjected toobject surface topography modulation and transmitting acquired data to a computer for data acquisition and processing; the computer processes an image shot by means of the video camera, solves the phase of stripes in a shot image, calibrates the whole measuring system to obtain a corresponding relation between pixel points on the video camera and pixel points on the projector is obtained, color textures and three-dimensional data of the object are obtained by adopting a decoding algorithm, and the color textures and the three-dimensional data are transmitted to a computer in a display instrument by means of a network.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a new method for collecting and displaying three-dimensional color data of a real scene. Background technique [0002] At present, the 3D profilometry based on the sinusoidal fringe image projection is one of the important methods to obtain the 3D surface of the object. It has developed rapidly because of its simple algorithm and high precision, and it has non-scanning and full-field performance. But during the measurement of spatially isolated objects, the fringe order is blurred during phase unwrapping, resulting in indistinguishable depth differences between surfaces of spatially isolated objects. Therefore, it is still difficult to collect 3D data of spatially isolated objects. A laser three-dimensional scanner is used to obtain the three-dimensional shape and color surface texture of the object, and then a real-color rainbow hologram is produced by a computer, and a good di...
