Intelligent automatic following method based on visual sensor, system and suitcase

Abstract

The invention provides an intelligent automatic following method based on a visual sensor. The method comprises the steps that the visual sensor collects the environment information of a suitcase relative to the owner of the suitcase, and sends the environment information to a data processing module; the data processing module identifies the suitcase owner to acquire the coordinate position of the suitcase relative to the owner of the suitcase; the data processing module sends an instruction to a drive module to drive the motor of left and right rear wheels of the suitcase to run; the suitcase and the suitcase owner are kept in a set range through a PID controller; and a main controller enables the suitcase and the suitcase owner to keep synchronization by predicting the next step of the suitcase owner. The invention further discloses a system and the suitcase, wherein the system and the suitcase use the method. According to the invention, the position of an obstacle is determined by directly using depth information acquired by the visual sensor to avoid the obstacle; the method has the advantages of high recognition accuracy and good obstacle avoiding effect, and is less susceptible to an external environment; and especially a variety of obstacle avoiding ways such as ultrasonic are combined to further improve the recognition accuracy and obstacle avoiding effect.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to an intelligent automatic follow-up structure based on a visual sensor. Background technique [0002] It is very inconvenient for people to travel at present, and they need to carry or push suitcases, so the applicant has designed a drivable generation of smart suitcases. The first generation of smart luggage is equipped with pedals for people to step on and driving wheels. People stand on the pedals and hold the trolley of the suitcase to control the suitcase to walk. However, the first generation of smart luggage has the following disadvantages: it cannot be followed automatically, and manual control is required. [0003] Therefore, the applicant applied for the second-generation smart suitcase. The second-generation smart suitcase mainly adopts the positioning and navigation based on the mobile phone Bluetooth base station. The basic principle is to use RSSI or signal strength...
