Realistic 3D model, model modification, integrated multi-sourcedata from air–space and ground, oblique photography
To address the insufficient utilisation and poor model accuracy of integrated data from air-space and ground integration in monolithic modelling, a realistic 3D model based on the integrated multi- source data is proposed. In the research results, when the aerial photography angle was 32◦, the accuracy was the highest while the error value was the smallest. For all checkpoints in the experimental area, the maximum errors in the three directions were 3.2, 4.6, and 4.4, all within the standard range. The results indicate that the real-time 3D model constructed based on integrated multi-source data from air-space and ground has high accuracy and good effects on structure and texture adjustment. The research is conducive to improving the efficiency and safety of substation construction and operation.
