Angle.
Fig. 2 is refer to, is a kind of concrete application scene of method for positioning position in kind provided in an embodiment of the present invention
Schematic diagram.
The concrete application scene is determines the particular location of the fish in water, specially:Set up the first reference ray and second
Reference ray, first reference ray dredges material from the vertical incident light of the close material of light, and the close material of the light is water, and the light dredges material and is
Air, because the first reference ray is from the thin material of the vertical incident light of the close material of light, therefore the first reference ray is in the close material of light
It is 0 that incidence angle in (water), which is 0 and dredges the refraction angle in material (air) in light,.Second reference ray does not hang down from the close material of light
Straight incident light is dredged in material, i.e., incidence angle of second reference ray in the close material of light (water) is i and dredges material (sky in light
Gas) in refraction angle be r.
Fig. 3 is refer to, is that the another of a kind of method for positioning position in kind provided in an embodiment of the present invention specifically should
With the schematic diagram of scene.
The concrete application scene is the fish from the bank, accurately to determine the particular location of fish, is specially:Set up the first ginseng
Light and the second reference ray are examined, first reference ray dredges material from the close material of light (water) with certain angle of inclination incident light
(air), i.e., people's skew fish certain angle on the bank is observed fish, now, the first reference ray entering in the close material of light
Firing angle is i1And the refraction angle in material is dredged for r in light1.Second reference ray is from the close material of light (water) with another angle of inclination
Incident light dredges material (air), and now incidence angle of second reference ray in the close material of light (water) is i2And dredge material in light
Refraction angle in (air) is r2。
It is readily appreciated that, the method for positioning position in kind can be applied not only to fish industry, accurately to determine fish
Position, realize accurate fishing, improve operating efficiency, other industry can also be applied to, such as from the article in salvaging water on the bank,
By being positioned exactly to the article in water to realize accurately fishing, subject matter on the bank is aimed at from water, with reality
Existing corresponding Job Operations etc..
Step S120, the position for the picture that the refraction in kind by light is formed is calculated according to the incidence angle and refraction angle
Put.

The vertical range that light dredges material (air) intersection is l, in kind (fish) and (fish) in kind into the vertical range of picture be h, due to
The material object is characterized with A, the material object into picture A ' characterize, therefore vertical range between the A and A ' is h.Then the second reference light
The incidence angle of line and refraction angle are respectively:Further obtained by solution formulaObtained by the law of refraction of light,
Therefore further obtainDue to n skies=1, refractive index n water of the water to air
=sin (r)/sin (i)=4/3, and then obtainThe h for it is in kind and it is in kind into picture
Between vertical range, while in order that the formula has meaning, needing to meet
And then obtainThen generally dredge thing in the close material of light and light for light
Propagated in matter, incidence angle needs to meetIt is just meaningful.
Fig. 3 is refer to, is that the another of a kind of method for positioning position in kind provided in an embodiment of the present invention specifically should
Use scene.
The intersection point of the intersection of material is dredged perpendicular to the close material of light and light using material object coordinate system, selection first are set up for origin
The reverse extending line of reference ray and the intersection point of the longitudinal axis are A1 (0 ,-y1), and the intersection point for choosing the second reference ray and the longitudinal axis is A2
(0 ,-y2), the intersection point for choosing the first reference ray and transverse axis is B1 (x1,0), and the intersection point for choosing the second reference ray and transverse axis is
B2 (x2,0), A ' is named as by the intersection point of the reverse extending line of the first reference ray and the direction extended line of the second reference ray
(x, y), the A ' (x, y) is the position of picture in kind, and then draws:
x1=ltan (i1)
x2=ltan (i2)
X=-tan (r are drawn by conversion1)y+tan(i1), and then obtain the position of the picture of material object.
Step S130, analyzes the position of the picture and obtains position in kind to calculate.
Fig. 4 is refer to, is a kind of schematic diagram of data analysis provided in an embodiment of the present invention.By rightAnalysis can draw the distance between picture and material object of material object, i.e. material object
As relative to climb h in kind, in the timings of incidence angle i mono-, and l direct proportionalities, i.e., it is in kind apart from the close material of light with
The vertical range that light dredges the intersection of material is bigger, then it is in kind into picture and material object between vertical range it is bigger.Meanwhile, work as l
One timing, h increases with i increase, then when material object dredges the vertical range of the intersection of material relative to the close material of light and light
One timing, picture in kind is when incidence angle i increases, and the distance at a distance of material object is more and more remote.
Fig. 5 is refer to, is the schematic diagram of another data analysis provided in an embodiment of the present invention.By rightCarry out analysis and find that, for each incidence angle i, picture in kind is in the close material of light
The change in depth of middle generation is equidistant, and in other words, picture in kind dredges the intersection of material relative to the close material of light and light
Distance is more remote relative to the intersection that the close material of light and light dredge material and more remote with material object.
It therefore, it can in this way estimate position in kind, by taking the fish in water as an example,
Wherein, p dredges material for image distance in kind from light and with a distance from the intersection of the close material of light, i.e., image distance in kind is from water
The distance in face, l is the distance in kind that material intersection is dredged apart from the close material of light and light, the i.e. distance in kind with the water surface.Known
Image distance separation in kind can pass through from the case of with a distance from the water surfaceCalculate
Go out the distance in kind apart from the water surface, that is, calculate the distance in kind apart from the close material of light and the thin material intersection of light, and then obtain
Particular location in kind.
It is readily appreciated that, according to x=-tan (r1)y+tan(i1) determine that the specific of material object can also be determined behind the position of picture
Position.
