An infrared ranging and anti-collision method and terminal

Abstract

An infrared distance measuring anti-collision method and a terminal. The method includes: when it is detected that the moving speed of the user holding the terminal is greater than the set threshold and the setting application on the terminal is turned on, starting the infrared ranging module on the terminal; The infrared ranging module makes the detection direction axis of the infrared ranging module parallel to the ground; controls the infrared ranging module to detect the distance between the obstacles around the user and the user and / or the moving speed of the obstacle; according to the distance , and the moving speed of the user and / or the obstacle, and output an alarm prompt to the user. A corresponding terminal is also disclosed. The infrared ranging anti-collision method and the terminal disclosed in the embodiment of the present invention have good environmental adaptability, can adaptively adjust the detection direction, and minimize the potential safety risks caused by the user using the handheld terminal while walking. Avoid accidental injury to users.

Description

technical field [0001] The invention relates to the technical field of intelligent terminals, in particular to an infrared ranging and anti-collision method and a terminal. Background technique [0002] With the rapid popularization of smart terminals, people rely more and more on smart terminals in their daily life. When people are walking or crossing the road, it is unavoidable to answer the phone or browse the information on the mobile phone or tablet. In these scenarios, since people's attention is mainly focused on the call or the information content of the smart terminal, there are great security risks. In order to reduce such risks as much as possible, the anti-collision function of smart terminals is in front of us. [0003] At present, infrared ranging technology has matured, and intelligent terminals such as smartphones already have anti-collision function technology. The principle of its implementation is to use the rear camera of the existing mobile phone for i...
