Abstract: Provided is an individual-tree segmentation method of UAV LiDAR point cloud based on canopy morphology. The method uses woodland data obtained by a UAV LiDAR to: extract initial canopies from a CHM based on a region growing algorithm, determine whether each initial canopy is a correct segmentation canopy according to the number of local density maximum points in each initial canopy, finely segment each wrong segmentation canopy according to canopy morphology to obtain an updated set of tree tops, and finally use each of the updated set of tree tops as a seed point for performing the region growing algorithm to thereby obtain a final individual-tree segmentation result. The method make full use of height information and density information contained in a tree point cloud; and under the guidance of the density information, a wrong segmentation tree can be more accurately identified.

Abstract: The array ultrasonic defrosting technology of fin-and-tube heat exchanger for quick freezing and refrigeration storage in food processing comprises vibration transmission plates installed on the heat exchanger surface, wherein the array ultrasonic transducer installed on each vibration transmission plate is connected with a time-sharing intermittent controller through the wire to form a transducer group, and each transducer group is connected in parallel to an ultrasonic generator with frequency tracking function, and is provided with a transducer shield. The loading mode of the time-sharing intermittent controller to the array ultrasonic transducer is intermittent loading. The array ultrasonic transducer is adopted to convert the high-frequency alternating current signal into the high-frequency vibration signal through the vibration transmission plate, and then shear stress is generated at the interface between the frost layer and the surface of the array ultrasonic transducer in a mechanical vibration mode, so as to remove the frost on the surface of the heat exchanger. Based on the present invention, the unit can be defrosted during operation, with the ultra-low temperature working conditions in the refrigeration storage and quick-freezing cabinet maintained and the stability of the system improved.
