Abstract

The invention discloses a star level bayonet all-in-one machine which comprises a lens for collecting light rays reflected by a photographic field. The lens transmits the collected light rays to a star level CMOS image sensor, the star level CMOS image sensor converts the light rays collected by the lens into image digital signals and transmits the image digital signals to an FPGA image processing module, the FPGA image processing module transmits the signals to a DSP algorithm processing module after processing an image, the DSP algorithm processing module conducts processing through various algorithms and finally outputs the image, and a power supply module is connected with the other modules and supplies power to the other modules. Through the characteristic that the CMOS image sensor is high in light sensitivity under low luminance, the star level bayonet all-in-one machine can obtain sufficient luminance and clearly capture an image under low environment luminance without using a flashing light; on the premise that driving of drivers is not disturbed, information such as license plate colors, license plate numbers, vehicle body colors and faces of the drivers in vehicles can be obtained at the same time, and the potential safety hazards during driving can be avoided.

Description

Starlight level bayonet socket all-in-one

Technical field

The invention belongs to monitoring trade field, be specifically related to a kind of starlight level bayonet socket all-in-one not using flashing light, avoid producing driver driving security implication.

Background technology

Bayonet socket snapshot one-piece machine is used for capturing the vehicle passed through, and General Requirements can obtain the information such as car plate color and number, body color, Che Nei driver's face.Conventional method uses color high-definition video camera to coordinate flashing light to realize, and the effect of flashing light is that light transmission automobile front windshield is got in car, makes shooting function see driver's face clearly.

And the shortcoming of conventional method can make flashing light have an impact to driver, cause driving safety hidden danger.But do not use flashing light, because car internal ratio car UV light is dark, video camera cannot capture Che Nei driver's face.

Summary of the invention

The present invention is to overcome shortcoming of the prior art, and a kind of starlight level bayonet socket all-in-one proposed.

Technical scheme of the present invention is:

Starlight level bayonet socket all-in-one of the present invention, comprise the camera lens of the light collecting scene reflections, camera lens and by focus on light transmission on starlight level cmos image sensor, starlight level cmos image sensor converts the light of lens focus to image digital signal, and this image digital signal is transferred to FPGA image processing module, FPGA image processing module to carry out Signal transmissions after image procossing to DSP algorithm processing module, DSP algorithm processing module carries out various algorithm process, finally export picture, power module respectively with starlight level cmos image sensor, FPGA image processing module, DSP algorithm processing module connects and powers.

Described FPGA image processing module comprises automatic exposure processing module, Automatic white balance processing module and wide dynamic process module.

Described DSP algorithm processing module comprises captures Trajectory Arithmetic module, image noise reduction algoritic module and captures logic judgment module.

The invention has the beneficial effects as follows:

The present invention utilizes photosensitive good characteristic under starlight level cmos image sensor low-light (level), enable starlight level bayonet socket all-in-one under comparatively low environment brightness, do not use flashing light, enough brightness can be obtained and capture picture clearly, make under the prerequisite not disturbing driver driving, the information such as car plate color and number, body color, Che Nei driver's face can be obtained simultaneously, avoid the potential safety hazard causing driving.

Accompanying drawing explanation

Fig. 1 is the structural representation of starlight level bayonet socket all-in-one of the present invention.

Embodiment

Below, with reference to drawings and Examples, technical scheme of the present invention is described in detail:

As shown in Figure 1, starlight level bayonet socket all-in-one of the present invention, comprise the camera lens of the light collecting scene reflections, camera lens and by focus on light transmission on starlight level cmos image sensor, starlight level cmos image sensor converts the light of lens focus to image digital signal, and this image digital signal is transferred to FPGA image processing module, FPGA image processing module to carry out Signal transmissions after image procossing to DSP algorithm processing module, DSP algorithm processing module carries out various algorithm process, finally export picture, power module respectively with starlight level cmos image sensor, FPGA image processing module, DSP algorithm processing module connects and powers.

When the present invention uses, after vehicle enters shooting area, the camera lens of starlight level bayonet socket all-in-one by the light transmission that focuses on on starlight level cmos image sensor, because under starlight level cmos image sensor low-light (level), photosensitive effect is good, can the light of focusing be converted to image digital signal, and this image digital signal is transferred to FPGA image processing module, FPGA image processing module carries out automatic exposure process, after Automatic white balance process and wide dynamic process, by Signal transmissions to DSP algorithm processing module, DSP algorithm processing module carries out the process of candid photograph Trajectory Arithmetic, image noise reduction algorithm process and the process of candid photograph Logic judgment, finally export picture.
