Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, an intelligent automobile auxiliary driving terminal in complex weather comprises a front automobile camera 1, a power supply module 2, an image acquisition module 3, a core control module 4, an early warning module 5 and a vehicle-mounted display screen 6; the front vehicle camera 1 is used for acquiring environment image information and transmitting the environment image information to the image acquisition module 3 through serial communication; the image acquisition module 3 is used for acquiring environment image information to obtain image parameter information and transmitting the image parameter information to the core control module 4 through serial communication; the core control module 4 is used for analyzing the image parameter information and driving the early warning module 5; the early warning module 5 is used for voice warning and driving the vehicle-mounted display screen 6 to carry out video warning; the vehicle-mounted display screen is used for displaying an alarm video; and the power supply module 2 is used for respectively supplying power to the image acquisition module 3, the core control module 4 and the early warning module 5.

The environment image information comprises weather environment image information and road condition environment image information. The power supply module 2 is connected with an automobile power supply through a vehicle-mounted USB for supplying power or the power supply module 2 realizes 12v to 220v through a boost inverter and then is connected with a DC power adapter for supplying power. The output end of the front camera 1 is connected with the input end of the image acquisition module 3 through an HDMI high definition cable.
