摘　　要：无人机倾斜摄影技术和Context Capture因具有自动化程度高、建模精度和效率高等特点而被广泛应用于三维建模中。本文使用无人机倾斜摄影技术和Context Capture分别对一辆SUV和一辆三厢轿车进行了三维建模,并对其进行了精度分析。结果表明,采用多条航线的无人机拍摄策略可以充分捕捉车辆各个侧面的细节信息。使用Context Capture构建的车辆三维模型细节清晰可辨,真实地反映了车辆外形。车辆特征点实测数据与航拍数据之间的最大相对误差为0.9%,确保了车辆三维建模的精度要求。The tilt photography technology of drones and Context Capture are widely used in 3D modeling due to its high level of automation,modeling accuracy,and efficiency.In this article the drone tilt photography technology and Context Capture are adapted to create 3D models of an SUV and a sedan respectively,and the accuracy is analyzed.The results show that using multiple flight paths in drone photography can fully capture detailed information of the vehicle from various angles.The 3D models of the vehicles constructed using Context Capture are clear and accurately reflect the actual shape of the vehicles.The maximum relative error between the measured data of the vehicle's feature points and the aerial photography data is 0.9%,ensuring the accuracy requirements of the 3D modeling of the vehicles.
