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

An apparatus capable of automatically identifying an obstacle in front of a mobile terminal, comprising

• a transmitting module,
• a receiving module, and
• a controller MCU module,
• wherein the transmitting module is in signal connection to the receiving module, the transmitting module and the receiving module are both in signal connection to the controller MCU module, and the controller MCU module is also in signal connection to a mobile terminal CPU;
• and
• wherein the transmitting module is configured to generate a laser transmitting signal and a difference frequency ranging signal containing phase information;
• the receiving module is configured to receive a laser transmitting signal when ranging and receive an infrared pyroelectric signal of a human body or a road surface when not ranging;
• and the controller MCU module is configured to identify a ranging signal and an infrared signal, and drive a corresponding voice data segment for playback and turn on a front-end main camera for working by means of the mobile terminal CPU so as to use voice to prompt a mobile terminal user to pay attention and to display a dangerous situation in front of the user by means of the front-end camera of the mobile terminal.
