摘要:
利用地铁工程施工现场的监控视频作为培训素材来源，对视频中发生险兆事件的危险区域进行识别划分，检测运动目标并根据跟踪算法识别工人轨迹。基于视频摘要提取技术提取现场险兆事件的视频关键帧，进而生成动态和静态视频摘要。利用武汉某地铁车站施工现场基坑临边高处坠落险兆案例生成动态视频摘要，更新施工工人个性化培训案例素材库，解决传统安全培训图片式、漫画式素材单一及获取困难等问题。
Abstracts:
The monitoring video of metro construction site is used as the source of training materials. The dangerous areas where near-miss events occur in the video are identified and divided. Moving targets are detected and workers′ tracks are identified according to the tracking algorithm. Based on video summarization extraction technology, the video key frames of on-site near-miss events are extracted, and then dynamic and static video summarizations are generated. Taking the near-miss case of falling at the foundation pit edge of a metro construction site in Wuhan, the dynamic video summarization is generated and the case material library of personalized training for construction workers is updated, solving the problems in conventional safety training such as simple and boring picture or comic materials and difficulty in acquisition.
