摘要:
随着现代工业技术的飞速发展，现代工业对安全的要求也越来越高。在工作环境中，由于一些原因如操作人员的注意力、判断力、视力范围的限制，极易发生作业设备超过警戒线而发生事故。文中利用计算机视觉技术，提出了一种虚拟安全空间的预警技术。通过两个摄像头采集实时环境图像，根据透视投影模型和矫正过后的图像中的点的三维位置坐标以及两个摄像头的坐标位置，计算出目标物的物理坐标，然后根据物理坐标计算出目标物和虚拟安全空间之间的距离，将其与安全距离比较，实现预警。仿真实验表明，此项预警技术具有良好的实时性和准确性，能够满足一定范围内的预警需求。
Abstract:
With the rapid development of modern industry,the modern industry's security requirements are also getting higher and high-er. In the work environment,due to some reasons such as the operator's attention,judgment,the limit of the visual range,prone to occur accident when the operating equipment exceeds the warning line. Using computer vision technology,a virtual secure space early warning technology is proposed,through the two camera to collect real-time environmental image,according to the perspective projection model and the three-dimensional position coordinates of the points in the corrected image and the two camera coordinate position,to calculate the physical coordinate of target object,then according to the physical coordinate to calculate the distance between the object and the vir-tual secure space,comparing with the safe distance,to achieve early warning. Simulation results show that this warning technology has good real-time performance and accuracy,can meet the requirements of early warning in a certain range.
