摘要
三维室内空间标注时易出现注记穿透墙体、注记密集以及视角变换导致的标注对象不明确、注记重叠等问题。然而,当前室内注记配置研究缺乏对标注对象不明确问题的解决。现有的注记重叠处理方法存在信息丢失或难以随视角变换进行快速动态调整等问题。针对上述问题,将三维模型与二维平面注记相结合,设计了指向式注记形式及其优化配置方法。该方法有效解决了标注对象不明确问题,支持重叠注记的快速检测,能随视角变换快速动态调整重叠注记位置,保持视域内所有注记信息的完整展示。通过对比多视角下的三维室内注记优化前后的实验结果,验证了该方法的有效性。
When annotating 3D indoor space,it is easy to have the problems of annotation penetrating through the wall,dense annotations,unclear annotation objects and overlapping annotations caused by the change of perspective.However,there lack solutions to the problem of unclear annotation objects in the current indoor annotation configuration research.The current overlapping annotation processing methods have the problems of information loss and being difficult to adjust annotations quickly and dynamically with the change of perspective.In order to solve the problems above,we designed a directional annotation form and an optimized configuration method based on the 3D space projection principle.This method can effectively solve the problem of unclear annotation,support rapid detection of overlapping annotations,quickly and dynamically adjust overlapping annotations with the change of perspective,and keep the complete display of all the annotation information in the field of view.Finally,we verified the effectiveness of this method by comparing the experimental results before and after optimization of multi-view 3D indoor annotation.
