Embodiment Construction

[0040] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0041] See figure 1 A method for realizing a modeling function based on 3D camera scanning includes the following steps:

[0042] Step 1: Capture the target object at angle a, establish a three-dimensional coordinate axis A with the 3D camera as the coordinate origin, and obtain the three-dimensional coordinates of all pixel points of the target object at angle a.

[0043] The 3D camera of the smart terminal captures the target object at an angle a, performs edge detection on the acquired image, and recognizes the edge contour of the target object.

[0044] Obtain the image information of the target object, generate an image information file, the generated image information file contains the pixel data of the target object in the obtained image; obtain the distance information of the target object, generate a distance information file, and th...

Abstract

The invention provides a method for realizing a modeling function based on 3D camera scanning, and the method comprises the steps: capturing a target object at an angle a, building a three-dimensionalcoordinate axis A, and obtaining the three-dimensional coordinates of the target object at all pixels of the angle a; establishing a three-dimensional coordinate axis B at the angle b, and obtainingthree-dimensional coordinates of all pixel points at the angle b; identifying common pixel points and non-common pixel points of the target object acquired at the angles a and b; calculating conversion parameters of the three-dimensional coordinate axes A and B; calculating the three-dimensional coordinates of the non-common pixel points at the angle b on the three-dimensional coordinate axis A; establishing a three-dimensional coordinate axis C at the angle c, and obtaining three-dimensional coordinates of all pixel points at the angle c; and identifying and judging whether non-common pixel points exist at the angle c and the angle ab, and if not, modeling the target object. According to the invention, the modeling function can be completed on one intelligent terminal, the size is small,the rapidness and convenience are obvious, and the daily acquisition and modeling operation is more convenient when the intelligent terminal is used.

Description

technical field [0001] The invention relates to the technical field of 3D modeling, in particular to a method and system for realizing modeling functions based on 3D camera scanning. Background technique [0002] Image modeling technology refers to the technology of collecting photos of objects through cameras and other equipment, and performing graphic image processing and 3D calculation by computer, so as to automatically generate a 3D model of the object being photographed. It belongs to the category of 3D reconstruction technology and involves computer geometry. , computer graphics, computer vision, image processing, mathematical computing and other disciplines. [0003] Judging from our long-term follow-up research in related technical fields at home and abroad, there are currently international institutions such as Microsoft, Autodesk, Stanford University, and MIT that have good results in image-based rapid reconstruction of 3D shapes. Research results, but only labor...
