摘要: |
为了解决输电线路监控中单目视觉缺少深度信息和双目视觉实时性低的问题,提出了一种基于双目视觉检测的优化方案。方案把传统双目视觉检测流程中监控阶段大量的计算量前移至准备阶段,建立输电线路立体空间模型。对该方法进行了详细说明,并利用Matlab对所提方法的可行性与有效性进行了实验验证。实验通过对导线坐标点三维重建、空间函数拟合和平面保护区域计算,建立了立体空间监控数据库。最后利用数据库检索对检测物进行入侵判断,结果识别出被测物所在空间位置属于在监控区域内。因此,所提方法可有效对输电线路空间进行建模与检测。 |

Abstract: |
In order to solve the problems of lacking depth information of single vision and low real-time of binocular vision in transmission line monitoring, this paper proposes an optimized scheme based on binocular vision measurement. This scheme moves the massive calculation in traditional binocular vision measurement process from monitoring stage to preparation and builds a stereo space model of transmission line. The details of the method are described, its feasibility and validity are examined by experiment via Matlab. A stereo space monitoring database is built in the experiment after wire coordinates 3D reconstruction, space function fitting, and protected area calculation. At last, the invasion of a measured object is estimated by database retrieval. The result shows that the space location of the measured object is belong to the monitoring area. Therefore, the proposed method is effective in transmission line space modeling and measurement.
