摘要
以实体植株为试验对象,对喷雾施药技术中红外对靶探测效果的不同影响因素进行实测分析,并在不同环境条件下对不同种类的植株进行试验研究.结果表明,植株外形、光照强度、探测器行走速度和植株间距对探测效果影响较为显著,而植株外形和光照强度的影响尤为明显.植株疏密度和光照强度与探测距离和探测范围均成正比.红外植株对靶更适用于枝叶茂密的大目标物且在较高光照强度下进行,同时在探测距离中点附近具有最好的探测分辨率,且对叶面反射率高的植株探测效果较好.探测器行走速度与个体植株能够被有效区分的最小间距之间满足线性关系.植株间距与探测器分辨率单调相关.温度和湿度对探测效果影响不大.不同植株红外对靶探测效果各具特点,但也具有普适规律.
Real plants were detected to study the detection effect and the affecting factors of infrared detecting technology. Different kinds of plants were detected in different environment to study the detecting effect rule by the same method. The results show that plant appearance, light intensity, walking speed and plant space have evident influences on detecting effect, especially plants appearance and light intensity. Plants density and light intensity is proportional both to detection distance and width. Infrared detection technology in plants targeting is more applicable for dense and large target reflectors under strong light intensity. It will get the best detector sensitivity near mid-point of detection distance and give better detection results for plants with high leaf reflectivity. Walking speed of detector has a linear correlation with the minimum distance of individual plant distinguished effectively. Plants space is monotonously correlative to detecting sensitivity. Temperature and humidity have little impact on the detection results. Different plants have different characteristics, but there is almost the same rule applicable.
