Abstract: Based on the camera module of Xiaomi 8, the accuracy level of smartphone in photogrammetry forward intersection is evaluated in this paper. Forward intersection experiments for ink box and bridge are performed, and the accuracy of the experimental results is verified by using professional photogrammetry software Agisoft PhotoScan. The ink box test results show that the accuracy of forward intersection is in millimeter level. The bridge test results show that the accuracy in horizontal direction is about 0.4 m, and the accuracy in vertical direction is about 0.6 m. The research results show that the camera module of contemporary smartphones has a certain application potential in high-precision photogrammetry.
Key words: photogrammetry and remote sensing technology; camera module of smartphone; 3D modeling; accuracy assessment
