Abstract: A method for controlling motion parameters of a pepper harvester based on combination of point clouds and images, including: (1) performing space-time calibration on a radar and a camera, constructing a data collection platform, and pre-processing image and point cloud data; (2) acquiring a real-time number of pepper in front of a harvester and an average height from canopies of pepper plants to soil through a point cloud, acquiring a cutting width and a pepper fruit proportion in front of the harvester through an image, and acquiring a comprehensive lowermost location of pepper fruits by combination of the point cloud and the image; (3) acquiring real-time motion parameters of the pepper harvester; and (4) controlling a real-time rotation speed, operation speed, and height of a drum using a fuzzy PID control method based on the comprehensive lowermost location of the pepper fruits and a predicted value of a feeding quantity.

Abstract: An elevator interactive terminal and an elevator interactive system. The elevator interactive system of the present invention comprises an elevator interactive terminal, configured with a social communication media module, wherein a user is registered as a first registered user in the social communication media module; and a server coupled to a communication bus of an elevator system, configured with the social communication media module and to register an elevator as the second registered user in the social communication media module, wherein, based on the social communication media module, interactive communication is performed between the first registered user on the elevator interactive terminal corresponding to the user and the second registered user on the server corresponding to the elevator.

Abstract: The present disclosure provides a rhythm point detection method and apparatus and an electronic device, and relates to the technical field of music analysis. The method includes that: an audio signal to be detected is acquired, and an audio feature curve is generated according to the audio signal to be detected; a music style of the audio signal to be detected is determined; a detection peak threshold and a detection frame width threshold are determined according to the music style of the audio signal to be detected; and a rhythm point of the audio feature curve is determined according to the detection peak threshold and the detection frame width threshold.
