| Abstract: | Taking fast fixed wing aircraft as the flight platform, by using a multi lens oblique aerial camera, a multi view image of 0.03m GSD has been obtained. By the fully automatic modeling technology, 3D model of a tilt photography has been made. The factors restricting the acquisition of high-resolution image, such as displacement of image, image storagespeed and safe flight altitude have been analyzed, and countermeasures have been put forward. The scheme is verified by the provincial pilot Zhanhua oblique photography project of smart city space-time big data platform. It will provides some references for the construction of high-resolution urban real 3D geographic scene. |
