Abstract

An infrared distance measurement collision avoidance method and terminal. The method comprises: turning on an infrared distance measurement module when the moving speed of a user of a hand-held terminal is detected to be higher than a set threshold value and the setting application on the terminal is turned on; adjusting the infrared distance measurement module according to a current inclination angle of the terminal relative to the horizontal position, so as to enable the axis of the detection direction of the infrared distance measurement module to be parallel to the ground; controlling the infrared distance measurement module to detect the distance between an obstacle around the user and the user and/or the moving speed of the obstacle; outputting an alarm prompt according to the distance, and the moving speeds of the user and/or the obstacle. The invention also discloses the corresponding terminal. The infrared distance measurement collision avoidance method and terminal disclosed by embodiments of the invention have good adaptive capacity to environment, can adjust the detection direction with self-adaption, thus reduces, to the maximum extent, potential safety risk for users caused by using the hand-held terminal when walking, and prevents users from accidental injury.

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...
