Active infrared vehicle-mounted night vision road condition detection and voice broadcast system

Abstract

The invention discloses an active infrared vehicle-mounted night vision road condition detection and voice broadcast system. The visual effect and the sight distance of a driver are effectively improved under poor illumination conditions or at night. An active infrared technology is adopted, a semiconductor laser is used as an infrared light source, a high-definition CCD camera is matched to shootan infrared image video, median filtering, a Laplace operator, threshold segmentation and morphological processing are combined to preprocess the image video, and a YOLO algorithm is combined to recognize, classify and calibrate obstacles in front of a vehicle. Meanwhile, an infrared receiver loaded on a vehicle head is used for receiving reflected light of a front obstacle, distance measurementof the front obstacle is achieved, the dynamic distance of the front obstacle is obtained, if the front obstacle is detected, data are transmitted to a mobile phone APP through Bluetooth, voice broadcast prompt of the front obstacle and the distance of the front obstacle of the vehicle is achieved, and the driving safety coefficient is improved.

Description

technical field [0001] The invention relates to the fields of vehicle safety assisted driving, Android APP development, etc., and specifically relates to an active infrared vehicle-mounted night vision road condition detection and voice broadcast system. Background technique [0002] When the car is driving at night, due to the limitation of external environmental conditions such as car lights and street lights, the driver's sight distance will be short, and the emergency situation on the road cannot be responded in time, which greatly increases the driving risk, about 55%. of traffic accidents occur at night. [0003] When driving at night, there are always dangers lurking in the darkness ahead. For example, in some cases, the driver cannot see the pedestrians who suddenly appear on the side of the road, or the person who is changing tires on the side of the road cannot be seen in time. Although modern lighting equipment can now provide excellent lighting effects, there is...

Problems solved by technology

[0005] Regrettably, although the development of a new type of vehicle-mounted infrared night vision system has become the consensus of the industry, only a few well-known automobile manufacturers have installed infrared night vision systems on their high-end cars or even concept cars. The infrared night vision system equipped on the car is complex in structure, expensive, and the technology is closed, so the effect is often not satisfactory
