摘　　要：为了向用户提供真实、交互、高效和可扩展的模拟体验,设计基于立体视觉技术的动画三维可视化仿真系统。通过双目相机采集目标相关信息,结合立体视觉技术进行图像特征匹配,获取高精度匹配的目标图像;将特征匹配后的目标二维图像,依照相机内外参数进行转换,获取目标特征点的空间三维坐标;通过纹理贴合获取纹理与几何信息对模型实施优化,结合双缓存技术生成目标连续动作的动画,利用视点漫游技术实现目标场景漫游。实验结果表明,该系统能够准确构建汽车的三维模型,不同视角下的特征点匹配精度高,误差控制在两个以内,且三维坐标定位准确。系统通过双缓存技术和视点漫游技术实现了目标场景的动态展示,为立体视觉应用提供了有力支持。In order to provide users with a real,interactive,efficient and extensible simulation experience,an animation 3D visual simulation system based on stereoscopic vision technology is designed.The target-related information is collected by binocular camera,and the image feature matching is combined with stereo vision technology to obtain the target image with high precision matching.Converting the two-dimensional image of the target after feature matching according to the internal and external parameters of the camera to obtain the spatial three-dimensional coordinates of the target feature points;The model is optimized by obtaining texture and geometric information through texture fitting,and the animation of the continuous motion of the target is generated by combining the double cache technology,and the roaming of the target scene is realized by using the viewpoint roaming technology.The experimental results show that the system can accurately construct the three-dimensional model of the automobile,and the matching accuracy of feature points from different perspectives is high,the error is controlled within two,and the three-dimensional coordinate positioning is accurate.The system realizes the dynamic display of the target scene through double cache technology and viewpoint roaming technology,which provides strong support for stereoscopic vision application.
