Specific implementation mode
High definition imaging detection device in tunnel described in the utility model as shown in Figure 1, 2 includes a circular ring shape base 1, and if
There are several continuous sections, each imaging unit 2 to be set to one for dry imaging unit 2,1 external peripheral surface of the circular ring shape base
On a section；The imaging unit 2 includes industrial camera 3,3 camera lens of the industrial camera towards outside, and focus is located at annulus
On the extended line of 1 diameter of shape pedestal.Preferably, the present embodiment is provided with 7 imaging units 2.It is furthermore preferred that as shown in figure 4, work
The angle of diameter and diameter where the focus of adjacent industrial camera 3 is 38 ° where the focus of industry camera 3.This design can be protected
The visual field for demonstrate,proving each adjacent cameras has effective lap, 278 ° of overall angle of visual field at 2.2 meters or more.
Due to insufficient light in tunnel, it can not meet the intensity of illumination requirement of camera acquisition image, it is desirable to provide compensation light
Source.In order to reach the purpose, a rotating base 4 is arranged in 3 front side of the industrial camera, and activity is fixed on rotating base 4
It includes two luminescence units 12 for being symmetrical arranged, being placed in parallel, each luminescence unit 12 to have light source part 5, the light source part 5
Structure is the same, specific as shown in Figure 4：Including a cavity, in the cavity, set successively along the differently- oriented directivity of industrial camera 3
Set LED light 6, Fresnel Lenses 7, transparent glass 8；The light source part 5 can be one of to be located on section tangent line
Rotary shaft is rotated, and the angle between two luminescence units 12 can be adjusted, enable light source according to the difference of tunnel height
Light filling efficiently most is carried out to camera.It should be appreciated that tangent line above-mentioned refer to its where section be tangential on similarly circle cut
Line.It is furthermore preferred that as shown in figure 5, adjusting remaining compensation light to realize the angle that each luminescence unit 12 is adjusted to facilitate
Source, the cavity side setting of the luminescence unit 12 of light source part 5 two are used for the scale indication pin of 5 rotation angle of display light source part
