Plant patrol method, device and system, and aircraft

The invention discloses a plant patrol method, device and system and an aircraft. The method comprises the following steps: acquiring first image data of a target area; determining the proportion of the number of the plants of the target type in the target area to the number of all plants in the target area according to the first image data; under the condition that the proportion exceeds a preset threshold value, collecting second image data of the plant of the target type; and generating a patrol result of the plant in the patrol target area according to the second image data. The technical problem that an existing agriculture and forestry patrol method is low in efficiency and accuracy is solved. 本申请公开了一种植物的巡查方法及装置、系统、飞行器。其中，该方法包括：采集目标区域的第一图像数据；依据第一图像数据确定目标区域中目标类型的植物的数量占目标区域中全部植物的数量的比例；在比例超过预设阈值的情况下，采集目标类型的植物的第二图像数据；依据第二图像数据生成巡查目标区域中的植物的巡查结果。本申请解决了目前农林业巡查方法效率低以及准确度低的技术问题。
