Problems solved by technology

But they all have certain defectives, namely the camera system can reflect the obstacle behind the car, but can't know the distance of the nearest obstacle; type of obstacle and the shape of the obstacle
For another example, there is also such a problem when civilian ships or yachts are parked

Embodiment Construction

[0020] refer to figure 1 , illustrate that the device of the present invention that can be combined with camera to monitor distance is made up of monitor 1, video digital signal and audio signal controller 2, ultrasonic signal driver and receiver 3, ultrasonic sensor 4 and power supply 5. The video digital signal and the audio signal controller 2 receive the field synchronous signal and the horizontal synchronous signal from the monitor 1 respectively, read the ultrasonic signal drive connected with the ultrasonic sensor 4 and the modulated echo pulse signal output by the receiver 3, And input the screen display signal and the audio signal corresponding to a certain distance into the monitor 1 respectively.

[0021] refer to figure 2 , illustrate that video digital signal and audio signal controller 2 in the device of monitoring distance can be combined with camera of the present invention are to be by single-chip microcomputer 6 and main clock oscillator 7, digital signal i...

Abstract

The invented device combines with the pickup for monitoring the target distance. The device includes the monitor, the video frequency digital signal controller, the audio frequency signal controller,the ultrasonic signal drive and receiver as well as ultrasonic sensor. The video frequency digital signal controller and the audio frequency signal controller are composed of the monolithic processor, the master clock oscillator, the impedance matching circuit for inputting digital signal, the character matrix clock rate oscillator, the voice output impedance matching circuit, the output impedance matching circuit and input impedance matching circuit. The video frequency digital signal controller and the audio frequency signal controller receive the field synchronization signal and the row synchronization signal output by the monitor, read out the ultrasonic signal drive, which links to the ultrasonic sensor.

Description

technical field [0001] The invention relates to a monitoring device and a monitoring method, in particular to a device and a method capable of monitoring target distance in combination with imaging. Background technique [0002] Existing distance monitoring devices, such as ultrasonic ranging radar, can only measure the distance of the target, and cannot meet the requirements when it is necessary to know the shape and distance of the target at the same time. For example, when a car is reversing, due to the limitation of the field of view, accidents such as collisions may occur, especially for buses and vans, if no one directs them, they cannot reverse. Existing vehicles currently on the market are equipped with a camera at the rear, which can display the situation behind the car through the screen of the monitoring device. There is also a reversing radar installed with ultrasonic ranging, and the obstacle behind the car can be displayed through the ...
