Abstract 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.
