Bluetooth headset performing shooting and rear view system using the same

Abstract

The invention provides a Bluetooth headset performing shooting, which comprises a Bluetooth radio frequency circuit and an antenna, and further comprises a shooting circuit, wherein the shooting circuit consists of a camera and an image processing chip; the image processing chip can transmit the information from the camera through the Bluetooth radio frequency circuit and the antenna. The Bluetooth headset performing shooting in the invention can provide a help to the driver to obtain the condition of the road at the back of the vehicle body during backing, and therefore the accident due to backing on road without knowing the barrier at the back can be prevented. The invention also provides a rear view system using the Bluetooth headset performing shooting.

Description

technical field [0001] The invention relates to a bluetooth earphone, in particular to a bluetooth earphone with camera function applicable to a rear view system and a rear view system using the bluetooth earphone. Background technique [0002] With the continuous improvement of people's income level and living standards, more and more people have private cars. During driving, reversing is often troublesome and less safe due to viewing angle problems. [0003] In order to facilitate people's reversing, the reversing radar operation was born. Most of the existing reversing radars on the market use the principle of ultrasonic distance measurement, that is, when the driver is reversing, the reversing radar is activated, and under the control of the controller, the probe installed on the rear bumper sends ultrasonic waves. , to generate an echo signal, after the sensor receives the echo signal, the controller performs data processing, thereby calculating the distance between t...

Problems solved by technology

[0004] However, because the reversing radar adopts the principle of ultrasonic ranging, if the obstacle behind the car body is a slope or a spherical body with a smooth surface, the echo signal sent by the probe is reflected by the slope or a spherical body with a smooth surface. Difficult to be received by the sensor; if the level of the obstacle behind the car body is lower than the level of the probe, the sensor will not be able to receive the echo signal

The above two situations may cause the controller to misjudge the situation behind the car body, resulting in the occurrence of reverse accidents

In addition, if a set of said reversing radar system is specially installed on the private car, it also needs higher cost.
