Abstract
The utility model relates to a high-speed industrial digital camera head; in the existing high-speed industrial digital camera head on the railway, when the sunlight or strong reflected light and the like straightly enter in a camera lens, the exposure of the shot pictures is great and clear pictures of partial time intervals can not be obtained owning to glaring effect. The high-speed industrial digital camera head comprises a shell (6), a laser transmitter (5) and a camera lens converting base (4) are arranged on the shell, a camera lens (1) is arranged on the camera lens converting base, an industrial linear array camera (3) is arranged in the shell corresponding to the camera lens, and a monochromatic narrow band pass filter (2) is arranged in front of the industrial linear array camera. The high-speed industrial digital camera head is suitable for a dynamic image detection system of rail sides of a railway system.
Description
Technical field:
The utility model relates to a kind of high-speed industrial digital camera device.
Background technology:
In order to ensure the railway freight-car traffic safety, railway system's system-wide has been applied (lorry, passenger vehicle, motor train unit) rail limit fault dynamic images detection system, in this system, used a kind of high-speed industrial numeral B need detect the position and taken, by browsing computing machine the body portions bitmap sheet of taking has been carried out fault detect by station inspector again lorry.In the use, video camera need be taken lorry bogie side frame and bottom simultaneously, when camera lens is gone in direct projections such as sunlight or strong reflection light, because glare effect, can cause captured picture exposure excessive, cause the part period can't obtain lorry parts picture clearly, make station inspector carry out effective fault distinguishing picture shot, had a strong impact on work efficiency, for the lorry traffic safety stays hidden danger.Fig. 1 is the light path synoptic diagram of general camera reversible-light shooting process.The light overwhelming majority that enters camera as shown in Figure 1 during the general camera reversible-light shooting is the direct sunlight line, and only accounts for a very little part that enters the total light ray energy of camera from the reflection ray of subject.Therefore cause the image exposure of the captured object of camera excessive, image blurring difficulty distinguishes that sunlight disturbed the immediate cause that produces when this was the camera reversible-light shooting.
Summary of the invention:
The purpose of this utility model provides a kind ofly can effectively eliminate surround lighting such as direct sunlight causes interference to the image of taking high-speed industrial digital camera device.
Above-mentioned purpose realizes by following technical scheme:
The high-speed industrial digital camera device, its composition comprises: housing, generating laser and camera lens conversion seat are installed on the described housing, described camera lens conversion seat is gone up camera lens is installed, corresponding camera lens position mounting industrial line-scan digital camera in the described housing is installed monochromatic narrow band pass filter before described industrial line-scan digital camera.
Described high-speed industrial digital camera device, the consistent wavelength of the centre wavelength of described monochromatic narrow band pass filter and generating laser transmitting illuminant.
The beneficial effects of the utility model:
1, the utility model is worked in coordination when reaching the filtering natural light by the linear lighting source of laser, monochromatic light narrow band pass filter and linear array industrial camera, the purpose that makes laser linearity lighting source enter camera lens by optical filter.Can reach by above-mentioned processing and to eliminate that the natural light high light disturbs, make linear array industrial camera (CMOS acquisition module) reach good reversible-light shooting effect.Adopt method that the utility model proposed can eliminate the adverse effect that image that the sunlight direct projection takes digital line battle array industrial camera causes effectively, the technique effect of realization is obvious, and picture quality obviously improves.
2, the utility model adopts totally enclosed integraty structure, and monochromatic narrow band pass filter is encapsulated between camera lens and the high-speed industrial camera, and failure rate is low, and is safe and reliable, freedom from repairs.
3, the utility model technology realizes maturation, can be according to the rig-site utilization demand, and the narrow band pass filter of customized different qualities.
4, the utility model compensatory light Scheme Choice is versatile and flexible, according to different arrowbands light-filtering characteristic, can select (infrared, far infrared, near infrared etc.) multi-wavelength's the linear lighting source of laser to do compensatory light.
5, the utility model can be applicable to take the main on the line car type (as lorry, passenger vehicle, motor train unit, locomotive) of present enforcement.
Description of drawings:
Accompanying drawing 1 is the light path synoptic diagram in the existing apparatus shooting process, the number in the figure 7 expression sun, label 8 expression subjects, label 9 expression camera heads.
Accompanying drawing 3 is structural representations of the present utility model.
Embodiment:
Embodiment 1:
The high-speed industrial digital camera device, its composition comprises: housing 6, generating laser 5 and camera lens conversion seat 4 are installed on the described housing, described camera lens conversion seat is gone up camera lens 1 is installed, corresponding camera lens position mounting industrial line-scan digital camera 3 in the described housing is installed monochromatic narrow band pass filter 2 before described industrial line-scan digital camera.
Described high-speed industrial digital camera device, the consistent wavelength of the centre wavelength of described monochromatic narrow band pass filter and generating laser transmitting illuminant.
The linear lighting source irradiation of laser subject is done light compensation during shooting, the linear lighting source of laser (is the infrared laser linear lighting light source of 808nm as centre wavelength) irradiation subject, according to the wavelength of the linear lighting source of laser camera is installed additional the narrow band pass filter consistent with optical maser wavelength the surround lightings such as direct sunlight that enter camera lens are carried out filtering, simultaneously the light of subject institute laser light reflected linear lighting light source is farthest received by narrow band pass filter and by the imageing sensor of line array video camera, and then under the condition that ambient light interference such as backlight are arranged, finish collection the vehicle picture rich in detail.
Claims (2)
1. high-speed industrial digital camera device, its composition comprises: housing, it is characterized in that: generating laser and camera conversion seat are installed on the described housing, described camera lens conversion seat is gone up camera lens is installed, corresponding camera lens position mounting industrial line-scan digital camera in the described housing is installed monochromatic narrow band pass filter before described industrial line-scan digital camera.
