Embodiment 1

[0158] see figure 1 Shown is a flow chart of a method for generating images that can be used for stereoscopic vision presentation, the method includes the following steps:

[0159] Step S102, acquiring image data of the object to be viewed; wherein, the image data includes three-dimensional point cloud data or three-dimensional data composed of data corresponding to a forward projection image and a forward depth image;

[0160] Step S104, according to the preset human eye binocular observation map and the human eye binocular observation coordinate system corresponding to the human eye binocular observation map, determine the coordinate transformation relationship corresponding to the image data of the object to be viewed; wherein, the human eye binocular observation The diagram includes a left-eye observation diagram and a right-eye observation diagram;

[0161] Step S106, according to the determined coordinate transformation relationship, convert the image data of the object...

Embodiment 2

[0166] Based on Embodiment 1, this embodiment of the present invention provides a specific implementation of a method for generating a stereoscopic image, for details, refer to the following steps:

[0167] Step 1: Obtain the 3D image data measured by the 3D machine vision measurement system, including the forward projection image and the forward depth image.

[0168] 1.1. Obtain the 3D data measured by the 3D machine vision measurement system:

[0169] Such as figure 2 As shown, it is a schematic diagram of a three-dimensional Cartesian coordinate system corresponding to the three-dimensional machine vision measurement system provided by the embodiment of the present invention. Since the 3D machine vision measurement system is a measurement system based on two-dimensional images, the images measured by the system satisfy the pinhole imaging model, so the final data measured by the measurement system also conform to the laws and regulations of the pinhole imaging model. Fea...

Embodiment 3

[0311] In combination with the foregoing embodiments, embodiments of the present invention provide an image generation device for stereoscopic vision presentation, see Figure 8 Shown is a structural block diagram of an image generating device for stereoscopic vision presentation, the device comprising:

[0312] The image data acquisition module 81 is used to acquire the image data of the viewed object; wherein, the image data includes three-dimensional point cloud data or three-dimensional data composed of data corresponding to a forward projection map and a forward depth map; specifically, the image data acquisition module 81 may include a first acquisition unit for acquiring 3D point cloud data of the object to be viewed, and / or a second acquisition unit for acquiring 3D data corresponding to the forward projection image and the forward depth image of the object to be viewed unit.

[0313] The coordinate relationship determination module 83 is used to determine the coordin...

Abstract

The invention provides an eye observation image generation method for stereo vision representation and a device and relates to the data processing technology field. The method comprises steps that image data of a viewed object is acquired; according to preset eye binocular observation graphs and an eye binocular observation coordinate system corresponding to the eye binocular observation graphs, a coordinate transformation relationship corresponding to the image data of the viewed object is determined; the image data of the viewed object is respectively transformed into left eye image data and right eye image data according to the determined coordinate transformation relationship; display transformation of the left eye image data and the right eye image data is carried out, and the binocular observation image of the viewed object is acquired. The method is advantaged in that the binocular observation image capable of representing stereo vision and being seen by eyes can be effectively generated, and a problem of relatively high cost existing in a binocular image making mode for representing the stereo vision in the prior art can be alleviated.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a method and device for generating images observed by human eyes for stereoscopic vision presentation. Background technique [0002] At present, the 3D point cloud data format is generally used as the digital description of the position and size of 3D space objects. The 3D data acquisition equipment corresponding to the data in this format mainly includes 3D scanners, 3D coordinate measuring instruments, remote sensing and aerial survey equipment, etc. 3D point cloud data and corresponding acquisition methods are generally used in various aspects such as engineering design, reverse engineering, geodesy, cultural relics protection, and 3D reconstruction. These point cloud data are generally the data superposition of multiple multi-angle measurement results, and the processing method of these point cloud data is basically post-processing. In order to achieve the app...
