基于增强现实的交互式产品三维虚拟展示设计

3D virtual display design of interactive products based on Augmented Reality

三维虚拟展示无法有效提取交互式产品的特征,导致去噪效果较差,标定及展示结果不准确。提出基于增强现实的交互式产品三维虚拟展示设计方法,通过增强现实技术中摄像机的成像模型及标定方法标定摄像机,提取产品特征,结合随机采样一致性算法匹配特征,获取图像的对极几何约束关系和基础矩阵,检索三维模型,实现交互式产品三维场景展示。实验表明,所提方法摄像机的标定精度在95%以上,信噪比为29.5dB,最高精度为99.2%,能有效增加信噪比,获取高精度的标定结果及展示结果。

The 3D virtual display failed to extract the features of interactive products effectively,resulting in poor denoising effect and inaccurate results of calibration and display.A 3D virtual display design method for interactive products based on augmented reality is proposed.The camera is calibrated through the imaging model and calibration method of the camera in augmented reality technology,and extracts product features.Apart from this,combining with the matching features of random sampling consistency algorithm,the polar geometric constraint relation and basic matrix of images are obtained,and the 3D model is retrieved to realize interactive 3D scene display of products.Experiment results show that the calibration accuracy of the proposed method is above 95%,the SNR is 29.5dB,and the highest accuracy is 99.2%.Therefore,the proposed method can effectively increase the SNR,and obtain high-precision calibration and display results.
