Laser photographing system special for bayonet

Abstract

The invention relates to a laser photographing system special for a bayonet. The laser photographing system comprises a control circuit, a vidicon and a double-view-field laser illuminator, wherein the vidicon and the double-view-field laser illuminator are connected with the control circuit; the laser photographing system is characterized in that a driving motor, which is used for directly switching an illumination view field of the double-view-field laser illuminator between a large view field and a small view field, is arranged on the double-view-field laser illuminator; the driving motor is connected with the control circuit; when a vehicle enters a bayonet position, the control circuit enables the double-view-field laser illuminator to be in large-view-field illumination, so that a license plate number is identified; when the vehicle is further close to the bayonet, the control circuit switches the double-view-field laser illuminator to be in the small view field through the driving motor; and a clear vehicle interior image can be acquired through the vidicon. According to the laser photographing system special for the bayonet disclosed by the invention, the driving motor is arranged on the double-view-field laser illuminator; therefore, switching of the illuminator between the large view field and the small view field can be effectively realized; and thus, vehicle license plate snapping and vehicle window perspective functions are effectively realized.

Description

technical field [0001] The present invention relates to a bayonet-specific laser camera system, and more specifically, to a bayonet-specific laser camera system that realizes license plate number recognition and vehicle interior status observation by switching between large and small fields of view through a laser illuminator. system. Background technique [0002] The supplementary light system in the road monitoring system is an essential part. In order to realize night monitoring, the visible light supplementary light method is mostly used at present, and a strong flash will be generated when the visible light supplementary light is used. There are many disadvantages in the use of strong flash to fill light. On the one hand, the human eye is poorly adapted to strong flash. Flash and remember the position of the bayonet, allowing criminals to bypass the bayonet in a targeted manner. [0003] At present, some manufacturers use the infrared flash mode.

[0003] At present, some manufacturers use the infrared flash mode. Although it has the characteristics of being invisible, it cannot meet the monitoring requirements for the occasions that require both the effective capture of the license plate and the ability to see through the inside of the window.
