Laser high-speed spherical night-vision device

Abstract

The invention provides a laser high-speed spherical night-vision device, belonging to the security monitoring device field. In the night-vision device, an imaging-lighting integrated machine is fixedly arranged in a seal cavity to form an integrated seal structure which is compact and has good rigidity, thus overcoming the defect that the bottom half part of the existing spherical shell needs to be made of a transparent material which has short service life; the night-vision device takes laser as an illumination source which can achieve long illumination distance, thus really realizing all-weather unattended monitoring; and meanwhile a wiper blade is arranged on a front end of an integrated camera, thus greatly lowering routine maintenance cost of a high speed dome.

Description

technical field [0001] The invention relates to a spherical night vision device used in the field of security monitoring, in particular to a laser high-speed spherical night vision device. Background technique [0002] High-speed dome is the abbreviation of high-speed intelligent spherical camera. It is a security monitoring terminal equipment integrating power transmission system, motion control system, imaging system, image processing and communication system. Because of its multiple functions such as video recording, position control, orientation and lens preset, target tracking and recognition, it is widely used in highways, urban intersection monitoring, factories, mines, schools, banks, urban communities and other monitoring occasions. [0003] If you want the high-speed dome to truly realize all-weather unattended monitoring, you must add an auxiliary lighting system for it at night or in a low-light environment. At present, the most widely used high-speed dome uses i...

Problems solved by technology

[0003] If you want the high-speed dome to truly realize all-weather unattended monitoring, you must add an auxiliary lighting system for it at night or in a low-light environment. At present, the most widely used high-speed dome uses infrared lights as auxiliary lighting. The advantage is low cost, but it also has a fatal disadvantage: the lighting distance is short, and it is a typical "myopia" at night

[0004] When the high-speed ball in the prior art is pitching, there is relative motion between the all-in-one machine and the dome cover. In order to ensure that the external scenery can always be observed through the all-in-one machine, the lower part of the dome cover must be made of transparent material. Poor, low strength, short service life

[0005] Moreover, the high-speed dome used outdoors will form a layer of dirt on the surface of the dome cover as the use time increases, which will seriously affect the imaging quality and even miss important monitoring information. Therefore, it must be removed from the installation after a period of use. Take it off the bracket to clean the dome cover, hang it back after cleaning, power on and debug, the whole process is more complicated, time-consuming, laborious, and less safe, which greatly increases the daily maintenance cost of the high-speed dome
