Image and picture acquisition device of road monitoring equipment

Abstract

The invention relates to an image and picture acquisition device of road monitoring equipment. The device comprises a camera sun shade (1), a dust cover (2), a camera protective cover (3), window glass (4), a camera body (5), a camera lens (6), an internal dust cover partition board (7), a filter control mechanism (8), a fan (9) and a supply air duct (10), wherein the filter control mechanism (8)is arranged between the camera lens (6) and the window glass (4); the internal dust cover partition board (7) is arranged between the front end of the camera body (5) and the window glass (4); the dust cover (2) is arranged at the front end of the window glass (4); the camera sun shade (1) is arranged on the upper parts of the dust cover (2) and the camera protective cover (3); and an air supply outlet of the supply air duct (10) is formed close to the window glass (4) on the dust cover (2). Compared with the prior art, the device has the advantages of improving the imaging definition of high-definition image pickup, and the like.

Description

technical field [0001] The invention relates to a road monitoring device, in particular to an image collection device for the road monitoring device. Background technique [0002] At present, in the high-definition road monitoring (camera pixel more than 1 million) industry, the image acquisition devices used for outdoor scenes have some defects in the optical system and equipment dustproof. [0003] 1. Optical system: [0004] At present, when high-definition cameras (cameras with more than 1 million pixels) are used in the actual field, the protective cover of the camera often adopts a simulated 400,000-pixel camera optical system. Using optical glass, the window glass has a great impact on the imaging of high-definition cameras. The higher the pixel of the camera, the greater the impact of the window glass on imaging. Although some optical glass is used, only optical glass cannot completely solve the imaging of high-definition cameras. the quality of. [0005] The came...

AI Technical Summary

Problems solved by technology

[0007] At present, the protective cover used by high-definition cameras in the field considers the dust prevention inside the protective cover in terms of dust prevention, but when the fan inside the protective cover is required to dissipate heat, due to the need for air flow, some use air exchange with the outside of the protective cover, so that The dust outside the protective cover may be brought into the protective cover, causing pollution to the lens of the high-definition camera. The high-definition image acquisition will be extended with time, and the effect of the image will gradually deteriorate, which will affect the imaging effect of the camera.

[0008] For high-definition photography, not only the dust-proof of the camera lens, but also the dust-proof of the entire optical system must be considered. The current high-definition camera protective cover considers dust removal measures outside the protective cover by installing a wiper device outside the window glass of the protective cover. However, the device must be used together with liquids such as water, and its effect is not satisfactory for high-definition photography. It will cause scratches on the glass surface, make the imaging effect worse, and affect the collection of images during use.
