Abstract

The embodiment of the application discloses an obstacle detection method and a device. A specific embodiment mode of the method includes steps of receiving at least one ultrasound wave data collectedby at least one ultrasound sensor in an ultrasound sensor array worn by a target user; confirming the distance between an instructed matter of every ultrasound wave data in at least one ultrasound wave data and the obstacle; based on the confirmed distance, generating a control signal of every output device in at least one output device, wherein the output device comprises a vibrating motor; sending every generated control signal to corresponding output device. Through the distance between the instructed matter of every ultrasound wave data and the obstacle, a control signal is generated, andthe accuracy of the obstacle detection is improved.

Description

Technical field [0001] This application relates to the field of computer technology, in particular to the field of Internet technology, and in particular to an obstacle detection method and device. Background technique [0002] In daily life, people with vision problems can’t see obstacles, making it more inconvenient to travel. People with vision problems can use the blind guide device to help travel. However, the blind guide devices in the prior art often have low detection accuracy and poor reliability. Summary of the invention [0003] The purpose of this application is to propose an improved obstacle detection method and device to solve the technical problems mentioned in the background art section above. [0004] In a first aspect, an embodiment of the present application provides an obstacle detection method. The method includes: receiving at least one ultrasonic data collected by at least one ultrasonic sensor in an ultrasonic sensor array worn by a target user; determinin...
