基于计算机视觉的虚拟安全空间预警技术
A Surveillance Technology for Virtual Security Space Based on Computer Vision
摘要
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.关键词
