摘要
消费级无人机用于测绘项目案例越来越多,为了研究其在石油天然气地面工程建设大比例尺测图需求下的作业程序和技术要求,分析了消费级无人机的发展趋势和技术能力,结合行业小面积大比例尺测图的特点,就外业数据采集执行各项技术指标、内业处理流程和质量检查,进行了系统性地研究和梳理。通过某拟建天然气净化厂1∶500比例尺测图案例,介绍了测区特点和消费级无人机性能参数,提出了项目实施过程中航线设计、像片控制点和检查点测量、内业处理等主要技术方法,分析了加密精度和模型精度,展示了项目成果,得出消费级无人机用于石油天然气地面工程建设大比例尺测图可行的结论。消费级无人机大比例尺测图具有广阔的应用前景。
Consumer UAVs are used in surveying and mapping projects.In order to study their operation procedures and related technical requirements under the demand of large-scale mapping in oil and gas surface facilities,the development trend and technical capacity of consumer UAVs are analyzed.Combined with the characteristics of mapping with small-area and large-scale in the industry,various technical indicators are collected and implemented for field works,while working procedures and quality control is performed for office work.Research and analysis have been made systematically for the above work.Based on the case of a 1∶500 scale mapping of a natural gas purification plant,this paper introduces the features of mapping area and performance parameters of UAV,lists the main technical methods in the implementation of the project,such as route design,photo control point and inspection point surveying,interior processing,analyzes the encryption accuracy and model accuracy,shows the achievements of the project.Conclusion has been reached that it is feasible to apply the consumer UAV in large-scale mapping for oil and gas surface facilities,which has a broad application prospect.
