Digital orthophoto map is widely used in the fields of basic surveying and mapping and national e-conomic construction,so it is necessary to continuously improve the technical methods for efficient produc-tion of high-resolution DOM.Combining with the production practice,technical method of real scene 3D model making DOM supported by oblique photography technology has been studied.The results of real scene 3D model can be regarded as the required results of DOM production.True digital orthophoto map can be generated by the real scene 3D model to quickly replace and repair the difficult areas as tall build-ings,so as to realize the DOM map surface repair.Comparing with traditional DOM production method,this technology does not need to carry out repeated aerial triangulation of UAV images with large data.It will make full use of real scene 3D model results,and effectively combines the reconstruction of real scene 3D model with DOM production to realize the efficient production of high-resolution DOM for UAV.
