Description
Technical field
The utility model relates to cannon axis calibration technique field, particularly relates to a kind of cannon multi-axial cord uniformity photoelectric detection system based on self-calibration technology.
Background technology
Cannon multi-axial cord consistency detection is the core index that in the big gun process of cannon school, static parameter detects, whether consistent for detecting cannon multiaxis (reference axis, firepower axle, laser beam axis, TV optical axis, laser beam axis, stablize servo reference axis and tracking radar reference axis), to ensure the accuracy at target of cannon.Current army is generally detected by the mode utilizing borescope to aim at target plate, the difficult point detected is that target plate is adjusted to the position vertical with reference axis, ensure that target plate can not rotate in plummet face simultaneously, namely to the adjustment (as shown by the arrows in Figure 8 the free degree) of target plate 5 frees degree, its shortcoming is that adjustment process is complicated, labour intensity is large, and technical requirement is high, army need badly one easily mode realize the conforming measurement means of cannon multi-axial cord.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of cannon multi-axial cord uniformity photoelectric detection system based on self-calibration technology, have simple to operate, do not need the adjustment losing time to carry out target plate, solution process processor completes automatically, precision high.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of cannon multi-axial cord uniformity photoelectric detection system based on self-calibration technology, comprise and be fixedly mounted on the camera of gun barrel gun muzzle, processor and target plate by means of fixture, described camera optical axis and barrel dead in line, described cam lens is etched with cross trellis differentiation line, described target plate is also etched with cross trellis differentiation line.
Described camera is digital camera, its data output end connection handling device, the supporting installation display screen of described processor.
Described target plate is marked with the position of cannon laser axis, infrared imager optical axis, TV optical axis, vehicle commander's mirror optical axis, tracking radar electric axis and firepower axle, described processor is used for the target plate real image of camera collection and standard picture to compare, and calculates the actual deviation of target plate position.
The beneficial effect adopting technique scheme to produce is: by being fixed on by camera on barrel gun muzzle, and make camera lens optical axis consistent with barrel big gun axle, on the camera lens of camera, corrosion has graduation, camera to the image graduation imaging of target plate being just superimposed with standard, benchmark optical axis during using this graduation as multi-axial cord consistency detection.Target plate is also drawn graticule as the foundation with cam lens graduation self-calibration.When target plate installs displacement and barrel axes normal, the standard self-calibration figure namely shown in Fig. 2.But actual target plate of laying is difficult to realize this ideal position.That is, actual target plate riding position be there will be the deviation of the free degree of 5 shown in Fig. 8, these 5 free degree deviations just there will be the shown self-calibration image shown in Fig. 3-7.The image of actual target plate position is the result of the multiple random combine of the free degree of 5 shown in Fig. 2-7.Be easy to decompose by image recognition algorithm within a processor.Then non-standard self-calibration figure is modified to standard self-calibration figure by image processing algorithm, to simplify multi-axial cord coherence measurement, compared with prior art, have simple to operate, do not need the adjustment losing time to carry out target plate, solution process processor completes automatically, precision high.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Set forth a lot of detail in the following description so that fully understand the utility model, but the utility model can also adopt other to be different from alternate manner described here to implement, those skilled in the art can when doing similar popularization without prejudice to when the utility model intension, and therefore the utility model is by the restriction of following public specific embodiment.
As shown in Figure 1, the utility model discloses a kind of cannon multi-axial cord uniformity photoelectric detection system based on self-calibration technology, comprise and be fixedly mounted on the camera 2 of gun barrel gun muzzle, processor and target plate 1 by means of fixture, described camera 2 optical axis and barrel dead in line, described camera 2 camera lens is etched with cross trellis differentiation line, described target plate 1 is also etched with cross trellis differentiation line; Described camera 2 is digital camera 2, its data output end connection handling device, the supporting installation display screen of described processor; Described target plate 1 is marked with the position of cannon laser axis, infrared imager optical axis, TV optical axis, vehicle commander's mirror optical axis, tracking radar electric axis and firepower axle, described processor is used for target plate 1 real image that gathered by camera 2 and standard picture compares, and calculates the actual deviation of target plate 1 position.
In embody rule process, the utility model is by being fixed on barrel gun muzzle by camera, and make camera lens optical axis consistent with barrel big gun axle, on the camera lens of camera, corrosion has graduation, camera to the image graduation imaging of target plate being just superimposed with standard, benchmark optical axis during using this graduation as multi-axial cord consistency detection.Target plate is also drawn graticule as the foundation with cam lens graduation self-calibration.When target plate installs displacement and barrel axes normal, the standard self-calibration figure namely shown in Fig. 2.But actual target plate of laying is difficult to realize this ideal position.That is, actual target plate riding position be there will be the deviation of the free degree of 5 shown in Fig. 8, these 5 free degree deviations just there will be the shown self-calibration image shown in Fig. 3-7.The image of actual target plate position is the result of the multiple random combine of the free degree of 5 shown in Fig. 2-7.Be easy to decompose by image recognition algorithm within a processor.Then non-standard self-calibration figure is modified to standard self-calibration figure by image processing algorithm, to simplify multi-axial cord coherence measurement, compared with prior art, have simple to operate, do not need the adjustment losing time to carry out target plate, solution process processor completes automatically, precision high.
The utility model as required, can promote the use of in the multi-axial cord coherence measurement comprising the armament systems such as radar, armed helicopter, guided missile, fill up the blank of the automatic detection means of multi-axial cord uniformity, effective raising measuring accuracy and testing efficiency, reduce labour intensity and the technical requirement of operating personnel.
