Description

image system backs a car

Technical Field

The utility model relates to an image of backing a car of car, in particular to image system of backing a car of adoption fly eye camera.

background

The car backing camera is an automobile camera which is installed at the tail of a vehicle and used, and is combined with a display screen installed in the vehicle to form a set of complete car backing image system. The camera structure and the theory of operation of backing a car that present market generally used: the shot scenery passes through the lens, the generated optical image is projected on the sensor, then the optical image is converted into an electric signal, the electric signal is converted into a digital signal through analog-to-digital conversion, the digital signal is processed by a DSP (digital signal processing chip), and then the digital signal is sent to a computer for processing, and finally the digital signal is converted into an image which can be seen on a screen. The reversing camera belongs to a wide-angle camera, and the visual field range is about 120 degrees horizontally and about 100 degrees vertically. The traditional car backing image adopts a single camera to realize the acquisition of car backing data, and the shooting range and the time field are both limited.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a car backing image system which can effectively acquire image information near the car tail of a car backing and has more comprehensive images.

In order to achieve the purpose, the invention adopts the technical scheme that: the utility model provides a reverse image system, includes fly's eye camera, image processing module, on-vehicle display screen, fly's eye camera sets up at the car afterbody, the output of fly's eye camera is connected with image processing module's input, image processing module's output and on-vehicle display screen are connected.

The fly-eye camera comprises a multi-lens assembly, an image sensor, an analog-to-digital converter, a DSP processing chip and a power panel, wherein the power panel supplies power for the image sensor and the DSP processing chip respectively, the output end of the multi-lens assembly is connected with the image sensor, the image sensor is connected with the DSP processing chip through the analog-to-digital converter, and the output end of the DSP processing chip is connected with the input end of the image processing module.

The multi-lens assembly is formed by combining a plurality of lens elements in a preset arrangement mode.

The utility model has the advantages that: utilize the fly's eye camera to gather the image information of the rear of a vehicle in the image of backing a car, image information is more comprehensive, and it is wider to shoot the angle, looks over the use when making things convenient for the driver to back a car.

Drawings

The contents of the expressions in the various figures of the present specification and the labels in the figures are briefly described as follows:

Fig. 1 is a schematic diagram of the structure of the reverse image system of the present invention.

Detailed Description

The following description of preferred embodiments of the invention will be made in further detail with reference to the accompanying drawings.

As shown in figure 1, the reversing image system comprises a fly-eye camera, an image processing module and a vehicle-mounted display screen, wherein the fly-eye camera is arranged at the tail of a vehicle, the output end of the fly-eye camera is connected with the input end of the image processing module, and the output end of the image processing module is connected with the vehicle-mounted display screen.

The fly-eye camera comprises a multi-lens assembly, an image sensor, an analog-to-digital converter, a DSP processing chip and a power panel, wherein the power panel supplies power for the image sensor and the DSP processing chip respectively, the DSP processing chip adopts a TMS320C3XDSP processor of TI company, the output end of the multi-lens assembly is connected with the image sensor, the image sensor is connected with the DSP processing chip through the analog-to-digital converter, and the output end of the DSP processing chip is connected with the input end of the image processing module. The image processing module is implemented using a FH8510 chip.

The working principle is as follows: the multi-lens assembly enters the image sensor through the photosensitive signals, the image sensor converts the optical signals into electric signals, then the electric signals are converted into digital electric signals through the analog-to-digital converter, the digital electric signals are transmitted to the image processing module through the DSP and are spliced to obtain spliced images of the images at the photosensitive angles of the plurality of photosensitive elements, so that the visual field is widened, the visual angle is large, and the backing view is convenient. Image splicing is realized in an image processing module, an FH8510 image processing chip runs an image splicing algorithm to realize image splicing, the image processing algorithm adopts a splicing algorithm in the prior art and is then preset in an image acquisition chip, the image splicing algorithm in the prior art, such as the image splicing technology research based on a camera translation mode in the 11 th No. 17 th No. 2009 in electronic engineering design journal discloses a fly eye image-shooting splicing method, and the method is run in the image processing chip to further obtain a display image of a vehicle-mounted display in a splicing manner.

A plurality of images shot through the fly-eye camera are spliced through the image processing chip to be displayed through the vehicle-mounted display screen, the visual range of the reversing image is expanded in the mode, and the shooting angle is wider.

It is clear that the specific implementation of the invention is not restricted to the above-described embodiments, but that various insubstantial modifications of the inventive process concept and technical solutions are within the scope of protection of the invention.
