摄影测量的高度自动化、易用性和成本效益，是近年来在业余用户中普及的重要因素。矛盾的是，当依赖需要实施控制程序的衍生3-D产品的准确性时，这种情况构成了挑战。在这方面，我们介绍了D3Mobile项目的一个案例研究：这是一个由国际摄影测量和遥感学会(摄影测量和遥感学会)资助的面向全世界参与者的完全在线竞赛。其目的是让参与者使用自己的手机获得基于现实的3-D模型，并批判性地检查隐藏在诱人的摄影测量现实主义背后的度量精度。前参与者模型的相对精度达到了1：2,000左右，与物体大小成比例。这些结果使人们对摄影测量目前的发展水平以及经过适当的能力建设和培训后为任何类型的用户提供的潜力有了一个了解。
The high level of automation, user-friendliness and cost-effectiveness of photogrammetry have contributed significantly to its popularisation among amateur users in recent years. Paradoxically, this situation poses challenges when relying on the accuracy of the derived 3-D products requiring control procedures to be implemented. In this context, we present a case study of the D3Mobile project: a fully online competition for participants worldwide funded by the International Society of Photogrammetry and Remote Sensing (ISPRS). The aim is for participants to obtain reality-based 3-D models using their own mobile phones and to critically examine the metric accuracy that hides behind the beguiling realism of photogrammetry. The relative precision of the former participants' models reached values around 1:2,000, proportionally to the object size. These results provide an idea of the current level of development of photogrammetry and the potential it offers for any kind of user after proper capacity building and training.
