Abstract

The invention relates to a control method and device of a walking stick with a millimeter-wave radar and an intelligent walking stick, and belongs to the technical field of smart houses. The control method comprises the steps: obtaining point cloud data within a preset range based on received echo signals of the millimeter-wave radar; analyzing the point cloud data to obtain motion information andfeature information of each detection object in a preset range; determining a classification result of each detection object according to the feature information of each detection object and a pre-trained classification model, and determining a target tracking object and a target obstacle according to the classification result of each detection object; and if the operation information of the target tracking object and the motion information of the target obstacle meet preset conditions, carrying out obstacle avoidance processing. According to the control method, automatic obstacle avoidance can be realized, and the safety of a user is improved.

Description

technical field [0001] The present application relates to the field of smart home technology, in particular to a control method and device for a cane with a millimeter-wave radar, and a smart cane. Background technique [0002] With the increasing number of aging population, the elderly in society often need to walk with the help of walking sticks to avoid obstacles in the road due to reasons such as inconvenient movement or blurred vision. [0003] As a walking aid for the elderly, smart canes have received high attention from the society. At present, the canes on the market generally have single functions, and most of them use laser radar, infrared, visual processing and other technical methods to detect surrounding objects. The detection sensitivity of these canes is low, and is greatly affected by external light and temperature factors, and the false detection rate is high. Contents of the invention [0004] In order to solve the above-mentioned technical problems or...
