Abstract
A laser vidicon apparatus, which comprises a vidicon and a laser emitter, which is characterized in that a group of laser lenses are arranged in the front of the laser emitter, the group of laser lenses consists of a lens fixation device arranged in the front thereof and a lens device that is movable under control, the movable lens device is kept horizontally with the laser generator, as well as the lens fixation device, the emitting angle of the laser can be adjusted automatically through the controllable movement of the lens device, to obtain the best illumination brightness and ensure the good monitoring effect. The operation is easy and the image is clear.
Description
Technical field
The utility model relates to a kind of laser camera device, refers more particularly to a kind of laser camera device that is applied to protection and monitor field.
Background technology
At present, the laser camera technique all is to utilize laser radiation that laser illuminator sends on observed object, gathers observed object image by the ACG end of video camera or camera inductive light intensity signal.Because observed object place environment difference, the brightness of light is also different, and light too by force or all can influence the sharpness of image too.
The emission angle of the laser illuminator on the market is all immutable.When video camera hot spot when proximad seeing at a distance will constantly become greatly, loss can appear in while laser itself, and the brightness meeting that causes shining sharply descends, and is difficult to record picture rich in detail; Conversely by as far as nearby the time then hot spot diminish, intensity increases, and is difficult to cover observed object, brightness simultaneously is too high also cause not fogging clear.The operation of controlling brightness of laser on the market all is a manual mode, implements very inconvenient, also is difficult to reach best monitoring effect.
Summary of the invention
For overcoming above-mentioned technological deficiency, the utility model aims to provide a kind of light luminance that can adjust generating laser automatically, guarantees the camera system of good shooting effect.The utility model is realized by following structure:
A kind of laser camera device comprises video camera and generating laser, it is characterized in that: the front end of described generating laser is provided with the laser lens group; Described laser lens group is by the fixed lens device of its front end and can constitute by controlled mobile lens devices; Described mobile lens device and generating laser and fixed lens device keep horizontal level.
The combination of described generating laser and laser lens group is positioned on the upper and lower or left and right side of video camera fuselage.
Described mobile lens device lower end and drive lead screw cover are fixed as one, and make up in vertical direction with drive lead screw by the drive lead screw cover; Drive lead screw is located at the motor front end of master control pcb board control; The master control pcb board is electrically connected with motor by the motor transmission line respectively, is electrically connected by the camera lens of camera lens transmission line with the video camera front end, and has the port that connects for external transmission lines.
The luminance signal that the utility model transmits by master control pcb board induction camera lens ACG end, and the lens devices of the motor-driven drive lead screw of control and combination with it moves, automatically adjust the Laser emission angle,, guarantee good monitoring effect to obtain best irradiation brightness.Easy and simple to handle, image is more clear.
Description of drawings
Fig. 1 is the structural representation of laser camera device.
Wherein: the observed object of 1-, 2-lens devices, 3-lens devices, the 4-drive lead screw, 5-drive lead screw cover, 6-generating laser, the 7-motor, 8-motor transmission line, 9-master control pcb board, the 10-external transmission lines, 11-camera lens transmission line, 12-video camera, the 13-camera lens, L1-lens devices spacing, the observed object of L2-is apart from laser lens group distance, the H1-laser radiation is to the spot diameter of observed object, α-laser radiation angle.
Embodiment
Be better understanding principle of the present utility model and structure, now be described further in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of laser camera device comprises video camera (12) and generating laser (6), and the front end of generating laser (6) is provided with fixing lens devices (2), and described generating laser also comprises can controlled mobile lens devices (3); Described lens devices (3) is positioned on the horizontal level between generating laser (6) and the lens devices (2).
Described lens devices (3) lower end and drive lead screw cover (5) are fixed as one, and make up in vertical direction by drive lead screw cover (5) and drive lead screw (4); Drive lead screw (4) is located at motor (7) front end of master control pcb board (9) control; Master control pcb board (9) is electrically connected with motor (7) by motor transmission line (8) respectively, is electrically connected by the camera lens (13) of camera lens transmission line (11) with video camera (12) front end, and has the port that connects for external transmission lines (10).
Its principle of work is as follows: when the distance between observed object (1) and laser lens group becomes L3 by L2, then send command adapted thereto according to the luminance signal that the end of the ACG in the camera lens (13) transmits by master control pcb board (9), drive lead screw (4) by motor transmission line (8) drive motor (7) front end is flexible, the lens devices (3) that drives with drive lead screw cover (5) one moves in the scope of L1, laser emission angle α is changed and makes L3=K*L2 (K is the laser loss coefficient); Otherwise when L3 heavy rain L2, laser emission angle α diminishes, and makes L2=K*L3.Can guarantee like this when the distance of laser radiation changes, the brightness of the hot spot of its projection not to be changed, ensure the imaging effect of video camera (12) by adjustment.
Described generating laser (6) is positioned on the upper and lower or left and right side of video camera (12) fuselage with the combination of laser lens group.
What should be understood that is: the foregoing description is just to explanation of the present invention, rather than limitation of the present invention, and any innovation and creation that do not exceed in the connotation scope of the present invention all fall within protection scope of the present invention.
Claims (2)
1, a kind of laser camera device comprises video camera (12) and generating laser (6), and it is characterized in that: the front end of described generating laser (6) is provided with the laser lens group; Described laser lens group is by the fixed lens device (2) of its front end and can constitute by controlled mobile lens devices (3); Described lens devices (3) keeps horizontal level with generating laser (6) and lens devices (2).
2, based on the described laser camera device of claim 1, its feature also is: described generating laser (6) is positioned on the upper and lower or left and right side of video camera (12) fuselage with the combination of laser lens group.
