The invention relates to the technical field of data sampling, and discloses an unmanned ship aperiodic sampling remote control method, which comprises the following steps: enhancing riverway remote sensing image data; training the riverway image representation extraction model and extracting an image representation vector of the enhanced riverway remote sensing image data; constructing a riverway curve recognition model and recognizing to obtain a riverway curve; marking a river channel curve position in the river channel remote sensing image data at an actual geographic position; and controlling the unmanned ship to carry out key sampling when passing through the inflection point of the river channel curve, and carrying out undersampling when passing through other positions. According to the method, linear stretching and pixel transformation are carried out on the river channel remote sensing image to improve the pixel contrast, image enhancement is realized, river channel curve position identification is realized based on the curve camber of the core pixel coordinates in the river channel curve area image and the image representation vector, and the unmanned ship is controlled to carry out key sampling when passing through the river channel curve. And non-periodic sampling remote control of the unmanned ship is realized.

    本发明涉及数据采样的技术领域,公开了一种无人驾驶船舶非周期采样远程控制方法,所述方法包括:对河道遥感图像数据增强;对河道图像表征提取模型进行训练并提取增强后河道遥感图像数据的图像表征向量;构造河道弯道识别模型并识别得到河道弯道;将河道遥感图像数据中的河道弯道位置标记在实际地理位置;控制无人驾驶船舶在经过河道弯道拐点时进行重点采样,在经过其他位置时进行欠采样。本发明对河道遥感图像进行线性拉伸以及像素变换提高像素对比度,实现图像增强,基于河道弯道区域图像中核心像素坐标的曲线弯度以及图像表征向量实现河道弯道位置识别,控制无人驾驶船舶在经过河道弯道时进行重点采样,实现无人驾驶船舶非周期采样远程控制。
