The article reflects the method of orthophotomap decivetion. The flow diagram of UAV data processing in Photomod is presented. The final processing results are presented in the form of an orthophotomap. The technology for constructing point objects for further error analysis is presented. The calculation of the plotted points in Excel for further error analysis was performed. Errors based on the tolerances that are proposed in the instructions for topographic survey are analyzed.

Uav Images

Unmanned aerial vehicle (UAV) and structure from motion (SfM) photogrammetry techniques are widely used for field-based, high-throughput plant phenotyping nowadays, but some of the intermediate processes throughout the workflow remain manual. For example, geographic information system (GIS) software is used to manually assess the 2D/3D field reconstruction quality and cropping region of interests (ROIs) from the whole field. In addition, extracting phenotypic traits from raw UAV images is more competitive than directly from the digital orthomosaic (DOM). Currently, no easy-to-use tools are available to implement previous tasks for commonly used commercial SfM software, such as Pix4D and Agisoft Metashape. Hence, an open source software package called easy intermediate data processor (EasyIDP; MIT license) was developed to decrease the workload in intermediate data processing mentioned above. The functions of the proposed package include 1) an ROI cropping module, assisting in reconstruction quality assessment and cropping ROIs from the whole field, and 2) an ROI reversing module, projecting ROIs to relative raw images. The result showed that both cropping and reversing modules work as expected. Moreover, the effects of ROI height selection and reversed ROI position on raw images to reverse calculation were discussed. This tool shows great potential for decreasing workload in data annotation for machine learning applications.

New System

This research has been done on Lubuk Sikarah subdistrict office city of Solok by collectingdata because the system that used to work still not optimal. Therefore, analysis of the data collected bythe system design tool that aims to optimized IMB data processing using Java Netbean programminglanguage and database MYSQL. This research method used is a field of research, there are researchlibraries and research laboratories. Thus, it produced a new system analysis using tools such as ASI(FlowInformation System), DFD(Data Flow Diagram), ERD(Entity Relationship Diagram), and the ContextDiagram. These tools will be generated several interrelated files in a database management. And thenew system is expected to improve the quality of IMB petition data processing sistem on suddistrict ofLubuk Sikarah Office.
