基于单目图像的三维重建算法实现

目前3D模型的重建主要利用正向建模的方式，预先设计好物体形状、大小、颜色、纹理等，通过建模软件（如C4D，3Ds MAX，Alias）生成所需的3D模型。这种方式对于设计人员的专业知识和软件操作能力要求较高，而且设计所需时间较长，实时性不高。针对这些问题，采取逆向建模方式，利用手机拍摄的图片通过相机标定和坐标转换等方法，在短时间内生成目标三维模型。实验结果表明，目标三维模型具有较高的精度，可以满足3D打印等一系列实际应用需求。

Implementation of 3D Reconstruction Algorithm Based on Monocular Image

At present, the reconstruction of 3D models mainly uses the forward modeling method to generate the required 3D models through modeling software (such as C4D, 3Ds MAX, Alias) through pre-designed object shapes, sizes, colors, textures, etc.This method requires high professional knowledge and software operation ability of the designer, and takes longer to design.It is not suitable for objects with complex shapes and structures.In order to solve these problems, a reverse modeling method is adopted.The pictures taken by mobile phones are used for camera calibration and coordinate transformation to generate a three-dimensional model of the object in a short time.Test results show that he model has good accuracy and can meet a series of practical application requirements such as 3D printing.
