简介:纸为帮助产品设计和机械系统的开发论述扩充现实的应用程序。扩充现实技术以如此的一个方法用一个交互真实的词集成一个交互产生计算机的词,他们作为一环境出现。AR技术能与不实际上是景色的部分,但是与在场的用户相关的信息提高真实世界的一种用户感觉活动。在AR系统介绍了3D建模的为特别改变数据的看法的一个模式正在允许用户以一个更全面的方法理解未来的机械系统,因此使设计进程比那更有效由常规今日的CAD系统支持了。介绍原型系统包含与AR系统综合的一个专家系统并且允许关于一个活动机器人的设计过程和认识到的构造上的问题的实际答案的连续的步送到知识设计者。有关AR的一条途径使系统用户能分析并且验证解决方案(作为3D代表了模型)相对真实景色/目标。因为在我们附近的真实环境经常提供是困难的在一台计算机复制的信息的广阔数量,这条途径是有益的。在一些情况中,一个AR系统的应用程序能是验证发达产品的一个最佳的方法。
简介:在3D抵抗力倒置最小化答案的数字,在倒置的一个固有的问题,考虑的数据的数量不得不大,优先的限制需要被使用。关于一个地质的异例的程度的地质、地球物理的数据是重要优先的信息。我们在3D建议形状限制的使用电的抵抗力倒置。三加权的直角的向量(正常和二正切向量)被用来在异例的边界控制抵抗力差别。异例的边界上的异例和限制的空间形状因此被建立。我们在3D抵抗力倒置的客观功能合并了空间形状限制并且与空间形状限制构造了3D抵抗力倒置方程。随后,我们使用了抑制方向向量和3D抵抗力倒置的重量的基于优先的空间形状数据的数字建模。我们建立了在方向向量和重量之间的一个合理范围,并且验证了使用空间形状的可行性和有效性在减少过多的结构和答案的数字的优先的限制。我们使用了优先的空间地抑制形状的倒置方法在广州地铁定位含水土层。空间形状限制从渗透雷达数据的地面被拿。含水土层的地点和形状的倒置结果与钻倒置的数据,和数字同意解决方案显著地被减少很好。
