影像快速拼接技术在基础测绘数据更新中的应用

Applications of Image Quick Mosaic on the Data Updates of BasicSurveying and Mapping

以黑龙江省基础测绘项目为依托,基于已有控制点资料和高精度影像数据,利用Pix4D软件自动化出图功能,开展了影像快速拼接技术在1∶10000矢量数据更新工艺中应用的技术流程研究与生产性试验。试验表明,其结果符合技术设计与规范要求。本方法为省级基础测绘城镇矢量要素更新提供了重要支撑。

Based on the project of basic surveying and mapping in Heilongjiang Province,this paper carries out the technical process research and production experiment of the application of image quick mosaic in 1∶10000 vector data updating process by automation in cartography of Pix4D,on the strength of old control points and higher precision images.The experiment shows that the results meet the requirements of the design and specification.This method provides an important support for the updating of vector elements of basic surveying and mapping at the city level.
