我们提出了一个协作式3D建模系统，它将复杂的3D建模过程解构为一组简单的任务，由非专业的人群工作人员执行。在给定显示目标对象的2D图像的情况下，每个群组工作人员被指示使用他们的视觉认知和现实世界的知识来绘制表示该对象的正视图的简单草图。然后，该系统通过整合从收集的草图集合中获得的几何信息来合成3D模型。我们展示了一组算法，可以从包含大量错误和不一致的不完整草图集合中生成干净的线条图和3D模型。我们还讨论了一个可以反复提高提交草图质量的众包工作流程。它引入了工人之间的竞争，使用基于同行审查的额外奖励，以及一个范例分享机制，以帮助工人了解任务要求和质量标准。所提出的系统可以在几个小时内生成各种对象的像样的3D几何图形。
We propose a collaborative 3D modeling system that deconstructs the complex 3D modeling process into a collection of simple tasks to be executed by nonprofessional crowd workers. Given a 2D image showing a target object, each crowd worker is directed to draw a simple sketch representing an orthographic view of the object, using their visual cognition and real-world knowledge. The system then synthesizes a 3D model by integrating the geometrical information obtained from a collection of gathered sketches. We show a set of algorithms that generates clean line drawings and a 3D model from a collection of incomplete sketches containing a considerable amount of errors and inconsistencies. We also discuss a crowdsourcing workflow that iteratively improves the quality of submitted sketches. It introduces competition between workers using extra rewards based on peer-reviewing as well as an example-sharing mechanism to help workers understand the task requirements and quality standards. The proposed system can produce decent-quality 3D geometries of various objects within a few hours.
