Description
Technical field
The present invention relates to peephole field, particularly a kind of looking-around observation glasses.
Background technology
Looking-around observation glasses use omnidirectional imaging system more at present, are mainly made of in omnidirectional imaging system three parts：It is photosensitive
Element, such as CCD device and imaging len, such as conventional imaging len or telecentric lens.Convex lens, speculum, convex lens are such as
Wide-angle lens.Convex reflecting mirror, its shape are quadratic surface, such as sphere, circular conical surface, hyperboloid and parabola or high order rotational symmetry
It is aspherical.
Ambient condition information is gathered using wide-angle lens, using the single view imaging characteristic of wide-angle lens, from three-dimensional
Object light in the range of 360 degree of space projects imaging sensor, obtains 360 degree of horizontal direction and the certain angle of vertical direction regards
The full-view video image of field range is spent, is allowed to produce good panorama cylinder figure on sensor target surface.Its main feature is that visual field
Scope is big.
Realize and realize that 360 ° of panoramas are observed with single-lens, installation site certainly will be required higher, and surrounding is set without other
It is standby to block visual field.For example panorama viewing mirror is subjected to panoramic on ship mast and is examined.But as closing armoring class battlebus etc., its
On have it is other sight take aim at equipment, radar etc., do not allow panorama viewing mirror to be mounted in eminence, because installation site is limited, be bound to cause 360 °
Scope visual field is blocked situation.
We design and employ observerscope, one in front and one in back install, 190 ° of visual field environment before preceding peephole collection, rear observation
190 ° of visual field environment after mirror collection, by image mosaic technology, with upper and lower two width picture splicing into a width figure display output, upper width
Figure is preceding 190 ° of range images, and lower width figure is rear 190 ° of range images.Height field angle is -10 °~+40 °, and is regarded using SOC
Frequency pretreatment technology, image processing algorithm program optimization is embedded in chip, realizes the acquisition process of panoramic picture.

The same sdi signal in 3 tunnels, then exported after equilibrium treatment, realize the identical high definition HD-SDI of 3 road signal indexs (1280 ×
720p) vision signal exports.
Product is realizing panorama overview function at the same time, and the situation sense of the external target location of personnel is multiplied for enhancing closing car,
Height, azimuth scale line are superimposed with display picture, while peephole can receive control computer communication instruction, by battlebus institute
Tracking position of object information superposition is in picture.
Looking-around observation glasses are converted into DC12V electricity through power supply conversion group 15 by the 28V power supplys of the external input of cable and supply forward sight
Peephole 1 and the work of rear-viewing mirror 2 use, and directly image sensor board 8, image flame detection module 12, image mosaic are superimposed
Module 13 is powered.Power module HZD20D-30S12, the wide pressure input power module of the army's of employing grade can be by DC 18V-36V
The input power of scope is converted into DC 12V power supplys needed for system.Output rated power is 20W, meets system power dissipation demand, together
When power panel periphery design protection circuit, plug connector has obvious Anti-misplug design.
Forward sight peephole 1 gathers the image in the range of 190 ° of battlebus front end orientation, after imaged, output distortion vision signal
To rear-viewing mirror 2.Rear-viewing mirror 2 gathers the image in the range of 190 ° of battlebus rear end orientation, after imaged, is observed with forward sight
The fault image that the input of mirror 1 comes is corrected through image processing module, sheared together, mirror image processing.Concatenation module spells two images
A width picture is connected into, since forward sight peephole 1 and 2 installation position of rear-viewing mirror are equipped with two meters of parallax range, the shape at from vehicle
Into 360 ° of panoramic pictures, height, orientation scale line are superimposed with panoramic picture；Looking-around observation glasses receive battlebus instruction at the same time, will
Target position information is superimposed upon in picture, final output all the way high definition SDI vision signals to battlebus display terminal.
Output image shows the interface of two width pictures up and down in same monitor, before upper width figure shows looking-around observation glasses
190 ° of pictures, lower width figure show 190 ° of pictures after looking-around observation glasses.
