The invention discloses a shooting method and device for oblique photography three-dimensional modeling. Bow-shaped air route flight is carried out on a target area; in a flight process, a pan-tilt controller makes a pitch axis motor, a transverse rolling axis motor and a direction axis motor point a camera lens to a set angle, triggers a camera shutter to shoot, and records space position coordinate information during shooting at the same time; shooting angles are 45 degrees in a front portion, 90 degrees in a lower portion, 45 degrees in a rear portion, 45 degrees on a left side and 45 degrees on a right side, and cyclic shooting is performed in sequence; an aircraft carries out one-time bow-shaped route flight on the target area so that photographing data of five angles can be acquired;a single-lens camera is installed on a three-axis pan-tilt with a pitching axis, a transverse rolling axis and a direction axis capable of rotating in a three-dimensional mode; and a size is small, weight is light, manufacturing cost is low, the device is installed on a small unmanned aerial vehicle, one-time bow-shaped route flight is performed on the target area, and data collection of three-dimensional modeling can be completed.
本发明公开了一种倾斜摄影三维建模的拍摄方法及其装置,它是采用对目标区进行弓字形航线飞行,在飞行过程中,云台控制器控制俯仰轴电机、横滚轴电机和方向轴电机将相机镜头指向设定角度,触发相机快门拍摄,同时记录拍摄时的空间位置坐标信息,拍摄角度为:前方45度、正下方90度、后方45度、左侧45度、右侧45度,依次循环拍摄;飞行器对目标区进行一次弓字形航线飞行,即可采集五个角度的拍照数据采集,采用单镜头相机安装在有俯仰轴、横滚轴和方向轴可三维旋转的三轴云台上,其体积小、重量轻、造价低,安装在小型无人机上,对目标区进行一次弓字形航线飞行,即可完成三维建模的数据采集。
