Description
Technical field
The utility model relates to a kind of device of laser stimulation shooting training, is specifically a kind of laser shooting Fresnel Lenses target assembly, belongs to target identification technology field.
Background technology
In the training of weapon laser shooting, take with CCD the application that the drop point of laser on target surface carries out image recognition, comparatively common.But this mode can only be carried out under darker environment (as indoor, backlight), use under the target surface of aiming cannot be placed on very bright sunlight.Because the irradiation brightness of sunlight, greatly exceed conventional laser point, on sunlit target surface, laser spots will be submerged in sunlight, and CCD can will not gather the image of laser spots.
Utility model content
For prior art Problems existing, the utility model proposes a kind of laser shooting Fresnel Lenses target assembly, sunlight and shooting laser are separated, effectively collects the image of laser spots, thus carry out image recognition indication of shots.
The utility model solves the technical scheme of above technical problem: provide a kind of laser shooting Fresnel Lenses target assembly, comprise laser gun, target surface, image processing apparatus and indication of shots computer, described target surface be transparent configuration, and be provided with gunnery target figure on described target surface; The described target surface back side is fitted with Fresnel Lenses, and the focus place of described Fresnel Lenses is provided with described image processing apparatus, and described image processing apparatus is connected with indication of shots computer by data wire; Described target surface, Fresnel Lenses and image processing apparatus are installed in target case.
The technical scheme that the utility model limits further is: aforementioned laser shooting Fresnel Lenses target assembly, described image processing apparatus front end is provided with optical filtering camera lens, optical filtering camera lens designs for optical maser wavelength used specially, the light only having this wavelength just by, remaining light will be stopped, and cannot enter image processing apparatus.
Fresnel Lenses target assembly is used in aforementioned laser shooting, and the transparent configuration of described target surface is provided with network structure, and mesh-portion can directly through laser.
Further, Fresnel Lenses target assembly is used in aforementioned laser shooting, and described image processing apparatus adopts the camera of CCD, and lens focus is 2.8-12mm; The image of CCD camera collection is delivered to computer and is identified, through the process of indication of shots software, will calculate the coordinate of laser spots, then carry out the output of the gunnery training indication of shots data such as laser spot position, number of rings, orientation.
The corresponding software of indication of shots computer of the present utility model adopts Image Processing and Pattern Recognition related algorithm, algorithm for image enhancement is used to strengthen target prospect region, Canny edge detection algorithm is used to obtain pop-off profile, SVMs is used to carry out training study and founding mathematical models to pop-off profile correlated characteristic, according to Mathematical Modeling perception pop-off information.
The beneficial effects of the utility model: the utility model owing to being provided with Fresnel Lenses before collection lens, effectively the light vertically injected can be focused on, image acquisition and processing device is arranged on the focus place of Fresnel Lenses, thus the accurate acquisition realized laser gun, not by the interference of extraneous veiling glare, overcome the defect that this type of laser training device needs to use under the environment that light is more weak; Greatly improve the range of application of training, improve the effect of training.

Detailed description of the invention
embodiment 1
The present embodiment provides a kind of laser shooting Fresnel Lenses target assembly, and structure as shown in Figure 1, comprises laser gun, target surface, image processing apparatus and indication of shots computer, target surface be transparent configuration, and on target surface, be provided with gunnery target figure; The target surface back side is fitted with Fresnel Lenses, and the focus place of Fresnel Lenses is provided with image processing apparatus, and image processing apparatus is connected with indication of shots computer by data wire; Target surface, Fresnel Lenses and image processing apparatus are installed in target case 6.
The Fresnel Lenses concrete structure of the present embodiment is identical with commercially available Fresnel lens structure, and concrete model is F350 × 350; The video camera of image processing apparatus selects Haikang prestige to look DS-2CC893P-A, and camera lens is selected and risen imperial 13VM2812AS II.
Laser gun 1 shoots laser to target case 6 a long way off, and laser spots will be beaten on target surface; Target surface 2, Fresnel Lenses 3, optical filtering camera lens 4 and CCD camera 5 are packaged into an entirety by target case 6, and laser image is delivered to computer 7 and carried out identification indication of shots process.
Target surface 2 and Fresnel Lenses 3 are close together, and CCD camera 5 is positioned at the focal position of Fresnel Lenses 3, and target surface 2 is partially transparent structure, outward appearance is gunnery target figure, designed by reticulate structure, mesh-portion can direct transmission laser, and target shape figure is in order to observe aiming to shooter.
As shown in Figure 2, the laser that distant place shooting comes is if L1, L2 or L3 are through Fresnel Lenses 3, and will change direction, all the CCD camera 5 at directive focus place, therefore CCD camera 5 can obtain the very strong indication of shots image of laser signal.Because optical filtering camera lens 4 has wavelength selectivity, can through the shooting optical maser wavelength of specifying, the light of other wavelength is all suppressed, cannot enter CCD camera 5.When there being the sunlight being irradiated to target surface, because the picture that is oriented of Fresnel Lenses 5 acts on, sunlight, by the Y point focusing to side, cannot enter CCD camera 5 and produce interference.The brightness of all the other veiling glares Z of target surface is much smaller than sunlight and laser, and energy also will be distributed in all directions, and what can enter CCD camera 5 is fraction, again because of the decay of optical filtering camera lens 4, also greatly weakens the image contributions gathered.By the characteristic of above-mentioned layout structure and each parts, this device can obtain the enough shooting laser images of signal to noise ratio under outdoor solar light environment, thus realizes the function of indication of shots.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
