Impeller diameter determination method and device based on satellite image and computer equipment

The invention provides an impeller diameter determination method and device based on a satellite image and computer equipment. The method comprises the steps of obtaining an initial satellite image of a target impeller, determining relative size information corresponding to the target impeller in the initial satellite image, and determining the diameter of the target impeller according to the relative size information. By implementing the method disclosed by the invention, the target impeller diameter can be quickly and accurately determined based on the satellite image, so that the communication cost and the time cost in the impeller diameter determination process are effectively reduced. 本公开提出一种基于卫星图像的叶轮直径确定方法、装置和计算机设备，该方法包括：获取目标叶轮的初始卫星图像，确定初始卫星图像中与目标叶轮对应的相对尺寸信息，根据相对尺寸信息，确定目标叶轮直径。通过实施本公开的方法，能够基于卫星图像快速、准确地确定目标叶轮直径，从而有效降低叶轮直径确定过程的沟通成本和时间成本。
