Embodiment Construction

[0023] First please refer to FIG. 1 , which mainly includes a camera 11 and at least two groups of ultrasonic sensors 21 and 22 at appropriate positions at the rear of the car 10 .

[0024] In this embodiment, the camera 11 is located at the center of the rear bumper 13 , and the bumper 13 is provided with an ultrasonic sensor 21 and 22 near the two sides.

[0025] The camera 11 can be a pinhole camera using CCD technology, which captures images and sends them to a connected image processing module (not shown in this figure).

[0026] Two groups of ultrasonic sensors 21, 22 are connected to a reversing radar host (not shown in this figure).

[0027] For the structure of the image processing module and the reversing radar host, please refer to figure 2 shown. in:

[0028] The image processing module includes at least:

[0029] A microprocessor 30, whose input end is connected with the reversing radar host 40, to receive the communication code sent by the reversing radar hos...

Abstract

The present invention discloses a car backing radar device with multichannel display function, and is characterized by that the proper position of car tail is respectively equipped with an ultrasonic inductor and a camera which are respectively connected to a car backing radar main machine and an image processing module, and the car backing radar main machine is wired with the image processing module, and the output end of the image processing module is connected with display positioned at the driver's seat. When the car is backed, firstly the driven can judge distance of obstracle after car to the car by means of image shot by camera, and when the car is approaching the obstracle, the reflected signal can be received by ultrasonic inductor, and converted into communication code by means of radar main machine, and transferred into image processing module, and the position and distance of the obstracle also can be displayed on display.

Description

technical field [0001] The invention relates to an additional device for a motor vehicle, more specifically a parking radar device with a multi-channel display function that has real-time image display and ultrasonic distance measurement functions so that the driver can more accurately grasp the situation behind the vehicle. Background technique [0002] "Parking" is a problem that every car driver must face. In theory, every driver should be familiar with parking, but the fact is often not the case. Sometimes the planning of the parking space is extremely narrow. In this case, the driver must have rich experience and skillful skills to smoothly pour the car into the parking space. When the driver's skills are not so skilled, unexpected collisions and collisions are difficult to avoid. In order to help drivers solve parking difficulties, a reversing radar has appeared on the market. It uses the principle of ultrasonic transmission and reception, and when the rear of the ca...
