Embodiment Construction

[0033] The present invention will be further described below in conjunction with accompanying drawing:

[0034] Such as figure 1 and figure 2 As shown, the automotive active safety system based on monocular vision includes an input device, a processing device and an output device. The input device includes a speed sensor 2 , an acceleration sensor 3 , a brake sensor 4 and a camera 1 . Camera 1 is installed in front of the car, such as figure 2 shown. The processing means refers to the processor 6 . The output device is the brake actuator 5 . The connection sequence is connected in sequence according to the signal direction, such as figure 1 shown. The speed sensor 2 measures the speed of the vehicle and provides the speed data to the processor 6; the acceleration sensor 3 measures the acceleration of the vehicle and provides the acceleration data to the processor 6; the brake sensor 4 detects whether the braking mechanism brakes, and This signal is provided to proces...

Abstract

The invention discloses an automobile active safety system based on monocular machine vision and a control method thereof. The system comprises an input device, an output device and a processor. The input device comprises a speed transducer, an acceleration transducer, a brake signal transducer and a camera. The output device is a brake actuator. The method comprises the following steps: performing internal and external calibrations by the camera; collecting target obstacle information by the camera, and calculating the distance between the automobile and the target obstacle in real time by the processor; calculating the safety distance under the current operating mode; and judging whether the distance between the automobile and the target obstacle is less than the safety distance, and determining whether the brake actuator brakes automatically according to whether a driver brakes. By adopting a method for measuring distance based on single-frame static images and a method for setting the safety distance reflecting the driving characteristics of the driver, the safety system has high precision and strong adaptability.

Description

technical field [0001] The present invention relates to an automobile safety system, and more specifically, to an automobile active safety system based on monocular machine vision and a control method thereof. Background technique [0002] Along with social development and economic progress, automobiles are more and more used in people's lives, and with the increase in the number of automobiles, traffic accidents have increased significantly. Facing the severe traffic safety situation, automobile consumers and government managers have higher and higher expectations for automobile safety. Traditional technologies and measures for occupant protection after accidents can no longer meet the requirements of modern transportation. The development of prevention-oriented The core advanced automotive active safety technology has become an urgent requirement of modern transportation. Most traffic accidents are caused by driver error. If the driver can be helped to take safety measur...
