摘要
随着现代物流业的发展,仓储安全越来越受到人们的重视,危化品仓库的仓储安全尤为重要。危化品仓库中障碍物的扫描、定位、还原过程,用于显示障碍物的位置、大小和形状等准确的数字化信息。根据这些信息,管理员可对仓库内部情况作出准确的判断,并采取恰当的措施,有效预防危化品仓库安全事故的发生。为了对危化品仓库的障碍物进行扫描、定位和还原形状尺寸,对激光扫描装置测得的数据进行了数据拟合。首先,利用激光扫描装置对无障碍物进行扫描,得到扫描数据并拟合建立正常状态。然后,对长方体障碍物的情况进行扫描,对得到的异常点进行数据拟合。最后,对圆柱体障碍物进行扫描,对收集到的异常点进行数据拟合。试验结果表明,采用该算法得到的长度最大误差值小于0.05m,能较好地实现图像还原,满足危化品仓库监控需求。该算法经济实用,具有很好的应用前景。
Along with the development of modem logistics industry, more and more attention has been paid by people on warehousing security, especially for the storage security of the hazardous chemicals warehouse. Scanning, positioning and reduction processes for the obstacles in hazardous chemicals warehouse are used for displaying accurate digitized information of the position, sixe,and shape of obstacles. In accordance with such information, administrators can make precise judgment on the situation inside warehouse, and take appropriate measures to effectively prevent occurrence of accidents in hazardous chemicals warehouse. In order to conduct scan, positioning and restore the shape and size of the obstacle, the data obtained by the laser scanning device are fitted. Firstly,the laser scanning device is used to scan the scene without obstacle; the scanned data are fitted to establish the normal state. Then, the rectangular obstacle is scanned; the data fitting is conducted for the abnormal points. Finally, the cylindrical obstacle is scanned and the data fitting is conducted for the abnormal points. The experimental results show that with this algorithm the maximum error of the length is less than 0. 05m, the image restoration can be better achieved, to meet the monitoring requirement for hazardous chemicals warehouse, the method is economical and practical, and has good application prospects.
