Description
Technical field
This utility model is related to a kind of overall view monitoring photographic head being easily installed, and belongs to safety monitoring technology.
Background technology
Overall view monitoring photographic head traditional at present mainly has fish-eye lens imaging system and rotating splicing-type panoramic imagery system
System.
Fish-eye lens is the mode of increase visual field most frequently, and visual field can reach 230 °, imitate with strong perspective
Fruit and the considerably long depth of field.The technology develops comparative maturity at present, it is difficult to increase visual field again.Jonny Gauvin are devised
A kind of imaging surface is oval fish-eye lens, increased the effectively utilizes area in the horizontal direction of sensor, not essence
On to increase visual field break through.And must necessarily be placed in for 0 ° Dao -90 °, i.e. monitoring camera in the visual field of vertical direction and supervised
The surface of control scene, this just has limitation in fit on, and is inaesthetic in some places, or even can produce some not
Necessary trouble.Also, although object-image relation is to correspond in theory, but is because complex structure, correct comparison and be stranded
It is difficult.In addition, in order to obtain the visual field more than hemisphere, high-quality fish-eye lens is typically employed to the lens of more than 10 and high-quality
The optical material of amount, system complex involve great expense.Cheap fisheye image effect is poor, resolution nor
It is very high.
Rotating splicing-type omnidirectional imaging system, which is mainly with the development of computer and digital image processing techniques, adopts
Normal optical camera lens is used, is rotated around the fixing axle vertical with optical axis, or around the multiple routines of fixing point installation of vertical optical axis
Imaging system, the sequence image for obtaining is spliced, and obtains made panoramic picture.It is broadly divided into two big class, a class
It is, around a fixing axle rotation, to be militarily mainly used in infrared scan early warning system using single or multiple cameras；The
Two classes are to install multiple cameras around fixing axle so as to cover all of visual field, such omnidirectional imaging system does not have scanning
Mechanism, because without servosystem, mechanism is relatively reliable and stable.Either which kind of system, its system are all non-
It is often complicated, high cost, in some instances it may even be possible to there is the situation of blind area.
In sum, at present in the urgent need to proposing more practical more efficiently overall view monitoring photographic head.
The content of the invention
The purpose of this utility model is to provide a kind of overall view monitoring photographic head being easily installed, and which can improve the resolution of system
Rate, is preferably minimized systematical distortion, farthest the true colours of reduction scenery.
What the technical solution of the utility model was realized in：A kind of overall view monitoring photographic head being easily installed, its feature
It is：First side plate, the second side plate and base plate composition housing, the first side plate, the second side plate constitute a right angle, the top of housing
Mirror surface is fixedly connected, interface module is arranged on base plate, above interface module, is sequentially arranged video image control and process
Module, image-forming assembly, connect imaging len above image-forming assembly, the mirror surface of imaging len alignment top, shield cover on shell
Seal on body.
The side plate of described housing can remove the second side plate and only retain the first side plate, i.e., consist of the first side plate and base plate
Housing.
The reflecting surface mirror, selection face type are parabola, with aluminium alloy as base material.
The imaging len, field of view angleα=43 °, focal length is selected for the imaging len of 6mm according to the angle of visual field and OR distances.
The image-forming assembly, chooses cmos imaging element.
Described interface module connection video display terminal and connection audio input-output device, conventional sensors, intrusion
Sensor, external alarm equipment.
Good effect of the present utility model is the resolution which can improve system, and systematical distortion is preferably minimized, maximum journey
The true colours of the reduction scenery of degree.
Description of the drawings
Fig. 1 is structure chart of the present utility model.
Fig. 2 is second structure chart of the present utility model.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described further：As shown in figure 1, a kind of overall view monitoring being easily installed
Photographic head, it is characterised in that：First side plate 6-1, the second side plate 6-2 and base plate 6-3 composition housings 6, the first side plate 6-1, second
Side plate 6-2 constitutes a right angle, and the top of housing 6 is fixedly connected mirror surface 1, and interface module 5 is arranged on base plate 6-3, connects
Video image control and processing module 4, image-forming assembly 3 are sequentially arranged above mouth mold block 5, are connected into above image-forming assembly 3 as thoroughly
Mirror 2, the mirror surface of the alignment of imaging len 2 top, shield are covered on.
The side plate of described housing 6 can remove the second side plate 6-2 and only retain the first side plate 6-1, i.e., by the first side plate 6-1
Housing 6 is constituted with base plate 6-3.
The reflecting surface mirror 1, selection face type are parabola, with aluminium alloy as base material；Numerical control machine wheeled litter goes out reflecting mirror surface shape
Afterwards, polished, plated film makes reflecting mirror.Selected shape is a quarter paraboloid.
The imaging len 2, field of view angleα=43 °, select focal length saturating for the imaging of 6mm according to the angle of visual field and OR distances
Mirror.
The image-forming assembly 3, chooses cmos imaging element；Have the advantages that small volume, integrated level are high, low in energy consumption, and
It is imaged relative to CCD, cost can be greatlyd save using cmos imaging component, it is often more important that cmos imaging component is directly exported
