Embodiment Construction

[0050] The present invention aims at the defect that in the existing 3D model reconstruction process, the key identification points must be manually marked by the user to create a 3D model, the operation is inconvenient, and the accuracy is low. The method of reconstruction enables image splicing and fusion without the need for the user to manually select key recognition points in the image, thereby achieving the purpose of improving the accuracy and speed of obtaining the 3D model.

[0051] The invention will now be described in detail in conjunction with the accompanying drawings and specific embodiments.

[0052] Such as figure 1 Shown is a flowchart of a three-dimensional model reconstruction method provided by a preferred embodiment of the present invention. In this embodiment, step S1 is first performed: using at least one depth camera to conduct multi-angle and continuous acquisition of a target to be modeled to generate multiple depth maps. The depth camera used in t...

Abstract

The invention relates to a three-dimensional model reconstruction method and system. The method comprises the following steps: S1, performing image acqusition on a target by using at least one depth camera to acquire a depth image of the target; S2, preprocessing the acquired depth image; S3, acquiring dense point cloud data according to the depth image of the target to reconstruct a target depth information point cloud grid; S4, combining and registering the multiple frames of reconstructed depth images to obtain a three-dimensional model. By implementing the method and the system, the accurate three-dimensional model of the target can be acquired without manually marking the target.

Description

technical field [0001] The present invention relates to computer vision technology, and more specifically, to a method and system for reconstructing a three-dimensional model based on a depth camera. Background technique [0002] The use of computer technology to build models of real objects is of great significance in various fields. For example, the reconstruction of the 3D model of the human body can realize the reconstruction of the posture, action, and shape characteristics of the human body in the computer. It provides the basis for applications such as gesture recognition and changing shape characteristics. [0003] However, in the existing 3D model reconstruction process, the user must manually mark key identification points to create a 3D model, which is inconvenient to operate and has low precision. Contents of the invention [0004] Aiming at the defect that the target must be manually marked in the existing 3D model reconstruction technology, the present inven...
