摘　　要：为了培养幼儿良好的阅读习惯,设计基于移动增强现实技术的幼儿智慧早教软件。识别数据库内平面图后,利用高通的Vuforia软件在线制作标识图。通过3DsMax软件建立三维场景模型,对所建立三维场景模型实施贴图、烘焙、渲染等操作,获取接近真实场景的效果后将其转化为FBX格式。将FBX格式文件与标识图共同导入Unity 3D软件中,Unity3D软件完成预制标识图与三维场景模型融合后,采用基于共面4点的姿态估计算法保障虚拟场景与实际场景高效融合,生成软件安装包完成软件设计。软件测试结果表明,所设计软件可实现场景自由拼合与情境交互,利用生动、趣味的卡通角色与场景可以帮助幼儿培养良好的阅读习惯。In order to cultivate children’s good reading habits, a smart early education software for children based on mobile augmented reality technology is designed. After identifying the floor plan in the database, use Qualcomm’s Vuforia software to make the logo map online;build a 3 D scene model through 3 ds Max software, and perform operations such as mapping, baking, and rendering on the established 3 D scene model to obtain an effect close to the real scene and convert it into FBX format, import the FBX format file and the logo map into the Unity 3 D software. After the Unity 3 D software completes the fusion of the pre-made logo map and the 3 D scene model, it adopts a posture estimation algorithm based on coplanar 4 points to ensure the efficient integration of the virtual scene and the actual scene. Generate a software installation package to complete the software design. The software test results show that the designed software can realize the free assembly of scenes and the interaction of the situation, and use vivid and interesting cartoon characters and scenes to help children develop good reading habits.
