Embodiment

Referring to Fig. 1 to Fig. 5, the utility model preferred embodiment is further elaborated.

A set of non-contact intelligent image geology is developed in the utility model and slides avalanche monitoring system, is known with image Other technology, but with the comparison of front and rear resulting image, it is quick to calculate geology slide displacement amount.

The equipment being mainly concerned with system includes scaling board 1, video camera 2, remote terminal 3.Laid on scaling board 1 LED light point, in the present embodiment by taking 9 points as an example, arranged with the column matrix of 3 row 3.Scaling board 1 is arranged on monitoring section, that is, may The dynamic point area of displacement can be produced.Stable site near monitoring section, which is set, sets up video camera 2, is furnished with one on video camera 2 MCU (Micro Control Unit, microcontroller unit), after the data of the extraction on video camera 2 are by MCU computings, pass through RS485 and Zigbee is transmitted to remote terminal 3.

The present embodiment uses " Three right-angle points standardization ", and calibrating external parameters are easy to be quick, greatly simplify required during demarcation Known conditions, directly from camera module monitoring picture calculate read geology slide displacement.Marked in the present embodiment The 9 LED light points set on fixed board 1, may be constructed multiple right angled triangles, using wherein any one right angled triangle conduct Three control points can calculate.Do not have to so image is identified, need to only compare and try to achieve first via the method for Three right-angle points The displacement vector of scaling board, and the displacement vector of second photo scaling board are opened, the three-shaft displacement of geology slip can be tried to achieve Amount.

Using three-point shape into world coordinate system, right-angled apices be world coordinates origin, 3 points in the position of world coordinates Put respectively A (0,0,0), B (X_wb,0,0)、C(0,Y_wc,0).A, 3 points of b, c A, B, C image are made, they are in image coordinate Position be respectively：(x_a0,y_a0)、(x_b0,y_b0)、(x_c0,y_c0), as shown in Figure 4.

It is theoretical according to pin-hole imaging, it is assumed that a points are motionless on imaging surface, and b and c is respectively moved to b along light₁And c₁, Z_cDirection Amount of movement be respectively：z_b1And z_c1, make ab₁With ac₁Parallel AB and AC respectively, so △ ab₁c₁It is similar and parallel with △ ABC, then b₁And c₁Image coordinate be：

Because ab₁⊥ac₁, so

(x_b1-x_a0)(x_c1-x_a0)+(y_b1-y_a0)(y_c1-y_a0)+z_b1z_c1=0 (2)

Δ ab again₁c₁It is similar to Δ ABC, it can obtain

Therefore

By (1) formula generation to (2) formula and (4) formula, solution non-linear simultaneous equations z_b1And z_c1Solution, delete plural number therein Solution and unsuitable solution, you can try to achieve suitable z_b1And z_c1Solution.

x_cA=px_a0=t_x y_cA=py_a0=t_y z_cA=pf=t_z

x_cB=px_b1 y_cB=py_b1 z_cB=p (f+z_b1)

x_cC=px_c1 y_cC=py_c1 z_cC=p (f+z_b1)

Wherein p is Δ ab₁c₁With the ratio of Δ ABC similar triangles, X_cA、Y_cA、Z_cAIt is to be translated towards in camera parameter Measure t (t_x,t_y,t_z) and we required by displacement.

The motion vector that first scaling board can be tried to achieve via the method for Three right-angle points is：

T=[t_x t_y t_z]

And the motion vector of second photo scaling board is：

t₁=[t_x1 t_y1 t_z1]

Therefore we can try to achieve the displacement of geology slip, as shown in Figure 5.

Δ T=[Δ t_x Δt_y Δt_z]

=[(t_x1-t_x) (t_y1-t_y) (t_z1-t_z)]

The utility model need not use high speed microcomputer or dsp chip, and system cost and power consumption are low, and framework is simple.Using " Three right-angle points standardization ", calibrating external parameters are easy to be quick, known conditions required during demarcation greatly simplified, directly from photography The monitoring picture of machine module, which calculates, reads the displacement that geology is slided.And calibration point is made up of LED, not by weather conditions system About, solar powered and wireless Zigbee network transmission is coordinated, a set of novelty can be formed entirely by being finally pooled to public 4G networks Weather automation geology slides avalanche monitoring system.

Above is the utility model preferred embodiment, if other utility models people institute under the utility model concept thereof Some simple replacements and change are made, should all be contemplated as falling within protection category of the present utility model.
