塔式起重机3D远程虚拟监控

Research on 3D Remote Virtual Monitoring for Tower Crane

为了向塔式起重机提供更为可靠、安全、完善的监控系统,基于虚拟现实技术研究了塔式起重机运行虚拟场景的参数化构建技术,分析了虚拟监控系统的3D裁剪算法和z缓冲算法,提出了利用DirectX技术开发虚拟场景渲染引擎,通过现场传感信息驱动塔机动作的虚拟监控系统.实验结果表明,本监控系统不仅提高了塔式起重机工作的安全性,并且具有较高的可扩展性、真实性、实时性与稳定性.

In order to achieve a more reliable and safe remote virtual monitoring system for tower crane, this paper, based on virtual reality technology, studied the method of creating the working scene with parameterized design, and analysed the algorithms of 3D clipping and buffering to optimize the performance of the system. The rendering engine of virtual scene was developed with DirectX, and the virtual tower cranes being driven with the data from on-site sensors. The experiments show that this virtual monitoring system not only enhances the security of tower crane, but also provides a more stable real-time system which is 3D, highly vivid and interactive.
