  • Method for detecting thickness of tree canopy based on ultrasonic echo signal
    Patent number: 11680793
    Abstract: The present invention relates to a method for detecting a thickness of a tree canopy based on an ultrasonic echo signal, and belongs to the technical field of agricultural machinery information sensing and detection. The present invention analyzes and discriminates a first effective peak and a last effective peak of the ultrasonic echo signal, obtains a first effective peak time and a last effective peak time, and calculates the thickness of the tree canopy according to a provided calculation formula, thus realizing the direct detection of the thickness of the tree canopy. This method has characteristics such as a high accuracy and a wide application range, and is applicable to the field of detection of the thickness of a tree canopy in industries such as agricultural machinery and forestry machinery.
