Embodiment 1

[0055] Embodiment 1, a system for rapidly reconstructing a 3D model based on the on-site environment, includes: a 720° camera, a 360° camera, and a core processing device.

[0056] Such as figure 1 As shown, the number of the 720° camera is one, which is set in the center of the scene environment. The 720° camera is composed of 6 CCDs, and the 6 CCDs are respectively located on the top, bottom, left, right, front, and back of the 720° camera. Among them, the four CCDs on the horizontal plane can capture the entire 360° space parallel to the horizontal plane, and the four CCDs on the vertical plane can capture the entire 360° space parallel to the vertical plane. There are four 360° cameras in total, and the four 360° cameras are symmetrically arranged around the scene environment. Both the 720° camera and the 360° camera communicate with the core processing device through a wireless / wired network.

[0057] The core processing device stores a factory planning CAD drawing, wh...

Embodiment 2

[0058] Embodiment two, such as figure 2 As shown, the method for quickly reconstructing a 3D model based on the on-site environment includes steps:

[0059] S101. Trigger the 720° camera and the 360° camera to take real-time pictures of the on-site environment, and obtain real-time pictures of the on-site environment including equipment.

[0060] In this step, also include:

[0061] A. Use the SIFT algorithm to splice the sub-pictures captured by the 6 CCDs in the 720° camera into a panoramic picture.

[0062] B. Splicing the sub-pictures captured by all 360° cameras with the above-mentioned panoramic pictures using the SIFT algorithm to form a real-time picture.

[0063] When the 720° camera and the 360° camera receive the shooting command, they enter the shooting mode and shoot the scene environment. The 6 CCDs of the 720° camera shoot the scene environment at the same time to obtain 6 sub-pictures, and the 4 360° cameras also shoot the scene environment at the same time...

Abstract

The invention provides a three-dimensional model rapid reconstruction method and system based on a field environment, and relates to the technical field of image processing. The three-dimensional model rapid reconstruction method comprises the steps of: triggering a 720-degree camera and a 360-degreee camera to shoot the field environment in real time, and obtaining real-time images of the field environment including equipment; superposing the obtained real-time images with factory planed CAD drawings; carrying out grey processing on the real-time images; grasping edges of equipment in the real-time images, and identifying the position areas of the equipment; carrying out equipment characteristic point grasping on the position areas of the equipment in the real-time images, and establishing an equipment characteristic point set; matching the equipment characteristic points with the corresponding points in the factory planed CAD drawings; and optimizing the equipment characteristic point set. The three-dimensional model rapid reconstruction method and system have the advantages that the method and system can be applied to three-dimensional modeling in the whole factory, the modeling speed is high, and rapid reconstruction is available for the occasions with frequent scene internal element changes.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method and system for rapidly reconstructing a three-dimensional model based on the on-site environment. Background technique [0002] 3D models are widely used in any place where 3D graphics are used. A 3D model is a polygonal representation of an object, usually displayed using a computer or other video equipment. The displayed object can be a real-world entity or a fictional object. Everything that exists can be represented by a three-dimensional model. [0003] With the development of computer technology and image processing technology, computer vision technology has been greatly developed. Target feature point matching and stereo reconstruction are the foundation and focus of computer vision technology. Image matching is the process of finding the same point or part between two or more images. Image matching has great application value in fields such as...
