Abstract

The present invention provides a machine vision-based movement control method, device and system. The movement control method is applied to controlling an intelligent shopping cart to follow a preset tracking target, wherein the intelligent shopping cart is provided with an image pickup device. The method includes the following steps that: the image pickup device acquires a scene image containing a target image, wherein the target image is corresponding to the tracking target in the scene image; the location and size of a preset search frame containing the target image is determined in the scene image according to the location and size of the target image; when the target image suddenly disappears or is displayed incompletely, and the size of the search frame is adjusted, and the location of the search frame is predicted through using a preset Kalman algorithm; and the movement state of the intelligent shopping cart is controlled according to the size of the adjusted search frame and the predicted location of the search frame. With the machine vision-based movement control method, device and system provided by the embodiments of the present invention adopted, the intelligent shopping cart can automatically follow the tracking target.

Description

technical field [0001] The invention relates to the field of intelligent control, in particular to a movement control method, device and system based on machine vision. Background technique [0002] With the improvement of living standards, people's material life is becoming more and more abundant, but when shopping in supermarkets, there are often embarrassing scenes caused by the inconvenience of pushing the shopping cart by hand due to special circumstances such as holding children. For this reason, smart shopping The cart technology came into being, and the smart shopping cart can move by itself, freeing people's hands. [0003] However, the smart shopping carts currently on the market cannot achieve the effect of automatically following shoppers, which brings inconvenience to shoppers to a certain extent. Contents of the invention [0004] The purpose of the embodiments of the present invention is to provide a movement control method, device and system based on machi...
