The embodiment of the invention provides a variable pesticide application control method and device based on image recognition. The method comprises the steps: adopting a laser radar to obtain a depthimage of an operation area; determining a crop leaf surface contour image according to the depth image; and determining leaf surface parameters according to the leaf surface contour image, and determining a pesticide application amount according to the leaf surface parameters, wherein the leaf surface parameters comprise the ratio of the gap area to the leaf surface area. According to the method,real-time identification and detection of the canopy region of the mixed crop can be realized, and target variable pesticide application is carried out according to the canopy leaf surface coverage degree of the detection result, so that the pesticide application accuracy can be improved.
本发明实施例提供一种基于图像识别的变量施药控制方法及装置,该方法包括:采用激光雷达获取作业区域的深度图像;根据所述深度图像,确定作物叶面轮廓图像;根据所述叶面轮廓图像,确定叶面参数,并根据所述叶面参数,确定施药量;其中,所述叶面参数包括空隙面积与叶面面积比值。该方法能够实现混合作物冠层区域的实时识别探测,根据探测结果的冠层叶面覆盖程度进行对靶变量施药,从而可以提高施药的精准度。
