Apparatus and method for automatically identifying obstacle in front of mobile terminal

Abstract

The invention discloses an apparatus and method for automatically identifying an obstacle in front of a mobile terminal. The apparatus is composed of a transmitting module, a receiving module and a controller MCU module. The transmitting module is in signal connection with the receiving module; and the transmitting module and the receiving module are in signal connection with the controller MCU module with the STM32 series. The controller MCU module is also in signal connection with a mobile terminal CPU. The transmitting module is configured to generate a laser transmitting signal and a difference frequency ranging signal including phase information. The receiving module is configured to receive a laser transmitting signal during ranging and receive an infrared pyroelectric signal of a human body or a road surface during a non-ranging process. The controller MCU module is used for identifying a ranging signal and an infrared signal, driving a corresponding voice data segment for playing and a front-end camera to start working by the mobile terminal CPU so as to warn a mobile terminal user in a voice manner, and displaying a dangerous situation in front of the user by the front-end camera of the mobile terminal. Therefore, the road condition in front of the mobile terminal can be identified automatically; and voice prompting is carried out timely.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, in particular to a device and method capable of automatically identifying obstacles in front of a mobile terminal. Background technique [0002] Mobile terminals (such as smart phones and PDAs) are more and more widely used in people's lives. In particular, at present, a large number of people who bow their heads on mobile phones only pay attention to the screen of their mobile phones, resulting in personal safety situations. During the mobile phone process, due to the blind area in front of the mobile phone, it may lead to being hit by a car when crossing a zebra crossing, falling into a ditch on the side of the road, stepping on an empty platform, stepping on an empty bridge ladder, tripping over various roadblocks (road construction materials, curbs), etc. How to overcome the above-mentioned problems, before encountering the above-mentioned dangers, remind in advance through t...

Problems solved by technology

[0002]Mobile terminals (such as smart phones, PDAs) are more and more widely used in people's lives. As a result, personal safety situations occur from time to time. For example, people who lower their heads while using their mobile phones may be hit by a car when crossing a zebra crossing due to the blind spot in front of the mobile phone, falling into a ditch on the side of the road, stepping on an empty platform, or stepping on an empty bridge ladder. Various roadblocks (road construction materials, curbs) tripping and other dangers, how to overcome the above problems, before encountering the above dangers, remind in advance through the mobile terminal to avoid the occurrence of danger is the need for the development of mobile terminal technology Technical Difficulties Solved
