Abstract

A vehicle intelligent device for automatically identifying road pit or obstruction in the technical field of vehicle intelligentialization comprises a binocular pinhole camera, a signal processor, a vehicle speed control mechanism and a voice prompting device; the output interfaces of the binocular pinhole camera are respectively connected with two image input interfaces of the signal processor, and the output interface of the signal processor is connected with the input interface of the vehicle speed control mechanism and the input interface of the voice promoting device in parallel. The binocular pinhole camera transmits the road scene image analog signals respectively collected to the signal processor; the signal processor processes two images in real time, identifies whether pit or obstruction exists in front of the current vehicle, and transmits identification result to the vehicle speed control mechanism and voice promoting device by control command. Once finding out pit or obstruction in the invention, the system can send out control command right now and the vehicle is automatically decelerated, thereby ensuring driving safety; and the incidence rate of road traffic accidents such as vehicle rear-end collision and impact can be obviously reduced.

Description

technical field

[0001] The invention relates to a device in the technical field of vehicle intelligence, in particular to a vehicle intelligent device for automatically identifying road pits and obstacles. Background technique

[0002] As we all know, deep pits and obstacles on the road often lead to major traffic accidents of fast-moving vehicles, especially on expressways, where any obstacles are absolutely not allowed on the road, otherwise, the consequences will be disastrous. Deep pits or obstacles on the road are often caused by goods dropped by vehicles in front or caused by man-made damage. With the rapid development of traffic and the rapid growth of car ownership, if vehicles do not have the technical function of intelligently identifying deep pits and obstacles, traffic accidents caused by sudden pits or obstacles on the road will inevitably increase significantly .

[0003] In order to avoid traffic accidents caused by the above situation, it is necessary to im...

Examples

Embodiment

[0039] The vehicle is equipped with the complete device of the present invention and the binocular camera parameter calibration is completed, the vehicle is started, and the device of the present invention enters the working state;

[0040] The binocular pinhole camera installed on the vehicle collects the scene image of the road in front of the vehicle, and the left and right pinhole cameras respectively transmit the analog signal of the scene image of the road in front of the vehicle collected by their respective output interfaces to the signal processing through the video cable. device;

[0041] The signal processor processes the two images collected by the binocular pinhole camera in real time, recognizes whether there is a deep pit or obstacle in front of the current vehicle on the image, and outputs the control command through the output interface of the recognition result; Under the action of the vehicle speed control mechanism, the vehicle can be automatically decelera...
