Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0020] However, there is a detection blind zone between the existing motor vehicle visual zones, and the driver will cause unnecessary traffic accidents due to misjudgment. For example, pedestrians who appear suddenly often make the driver dodge in a hurry, causing unnecessary personal injury, and injuries to pedestrians are often caused by too late or improper operation, or even more serious injuries due to operational errors.

Abstract

The invention discloses a method for detecting a pedestrian through laser, and the method is suitable for a car-mounted detection device. The device comprises a laser radar device, an indication lamp, a loudspeaker and a horn which are installed on a lattice arch. The method includes the following steps that the laser radar device emits a wave beam to scan the pedestrian in front of a car, and the wave beam is reflected to a sensor when encountering the pedestrian; an A / D converter converts output signals of the sensor into a digital format from an analogue format; a single chip microcomputer analyzes the output signals of the sensor; when the distance between the pedestrian and the car is smaller than a first distance, the indication lamp is lighted; when the distance between the pedestrian and the car is smaller than a second distance, the loudspeaker is started; when the distance between the pedestrian and the car is smaller than a third distance, the horn whistles.

Description

technical field [0001] The invention relates to the field of vehicle electronics, in particular to a method for detecting pedestrians through laser light. Background technique [0002] The development of automobiles not only has a huge effect on social economy, but also has an important impact on human life. Automobiles have become the main means of transportation for people to travel, and their convenience is unmatched by airplanes, ships and trains. [0003] As an emerging economy, China has become the world's largest automobile consumer. At present, the number of motor vehicles in my country has exceeded 100 million. There are too many cars, roads are blocked, and there are more and more traffic accidents. Many traffic accidents are caused by drivers with blocked vision or inexperienced drivers, which can be completely avoided. [0004] However, there is a detection blind zone between the existing motor vehicle visual zones, and the driver will cause unnecessary traffic...
