Cart with active following function

Abstract

The invention discloses a cart with an active following function. The cart comprises a frame, wheels, a driving mechanism, a main control board arranged on the frame and a camera component, wherein the camera component comprises a first camera for detecting a first image in front of the cart and / or a second camera for detecting a second image behind the cart, the main control board comprises an information processing module based on a pre-established permission surface image information database, the information processing module is used for retrieving and comparing the first image and / or thesecond image with an authority surface image in the information database, if the first image or the second image is matched with the permission surface image, and reduction of the human body in the first image or the second image is further analyzed, the main control board controls the driving mechanism to drive the wheels to rotate for autonomous following. The cart is advantaged in that the carthas a surface recognition function, the pushing permission of the cart is controlled, meanwhile, autonomous following of the cart can be triggered, and the cart has an obstacle avoidance function.

Description

technical field [0001] The invention relates to the field of power-assisted pushcarts, in particular to a pushcart with an active following function. Background technique [0002] The cart is a very convenient means of transportation. With the advancement of science and technology, the power-assisted cart is increasingly favored by consumers. The power-assisted cart uses a driving mechanism to drive the wheels of the cart to reduce the burden of manpower. On the basis of the current market, there are carts that can automatically follow the user, and the user does not need to directly push or pull the cart. For example, the utility model patent whose patent announcement number is CN205273577U discloses a child stroller that can automatically follow, and uses a follow-up power assist system to enable the stroller to automatically follow the position of the transmitter; another example is the utility model patent announcement number CN207182094U The patent also discloses a sma...

AI Technical Summary

Problems solved by technology

[0004] 1) It must be carried with you. If you forget to carry the beacon or the beacon is missing or damaged, the automatic follow function cannot be realized;

[0005] 2) Anyone holding the beacon can guide the cart, causing safety hazards;

[0006] 3) The following function needs to be turned on or off through the beacon, which is cumbersome to operate

[0007] In the existing technology, there is no technology that can directly call the cart to follow independently without passing through the beacon
