The invention discloses a low-altitude three-dimensional data acquisition method and system for an unmanned aerial vehicle, and particularly relates to the field of three-dimensional data acquisition, and the method comprises the steps: selecting a four-rotor unmanned aerial vehicle, carrying a laser radar, a high-resolution camera and high-precision positioning equipment, and carrying out the low-altitude flight; the laser radar collects surface information, and the camera shoots a ground image; then, processing the acquired data, including abnormal value removal, missing value supplementation, image denoising and image enhancement; thirdly, converting the processed data into three-dimensional point cloud data, and identifying an image to obtain an actual appearance and a name of a target object; and finally, performing high-precision topographic surveying and mapping and three-dimensional modeling according to the processed three-dimensional point cloud data to generate a final three-dimensional model.

    本发明公开了一种无人机低空三维数据采集方法及系统,具体涉及三维数据采集领域,本发明选择四旋翼无人机并搭载激光雷达、高分辨率摄像机和高精度定位设备进行低空飞行;激光雷达采集地表信息,摄像机拍摄地面图像;然后,对采集到的数据进行处理,包括异常值去除、缺失值补充、图像去噪和图像增强;接着,将处理后的数据转换为三维点云数据,并对图像进行识别,得出目标物体的实际样貌和名称;最后,根据处理后的三维点云数据进行高精度地形测绘与三维建模,生成最终的三维模型。
