In Fig. 1 to Fig. 2, label 1 is first image；Label 2 is second image；Label 3 is the 3rd image；First
In image 1 and first image 3, A, B, C are for demarcating thing, in second image 2 A ', B ', C ' be with in first image 1
The demarcation thing that A, B, C are corresponding.
In actual photographed, the biggest difference reflected in Fig. 1 and Fig. 2 not figure, but in order to describe the problem,
In fig. 1 and 2, the biggest difference is given.
Detailed description of the invention
As shown in Figure 1 to Figure 3, the first image 1 and the second image 2 are adjacent two two field pictures being continuously shot, and it can be
Carry out shooting may not be of obtaining with unmanned plane, for the purpose of simplifying the description, in Fig. 1 to Fig. 3 by three demarcate thing as a example by enter
Row explanation, demarcating thing is actionless object.
The present invention is for eliminating the processing method of camera shake, and it comprises the following steps:
A () shoots adjacent two two field pictures that is first image 1 and the second image 2 with camera, based on the first image 1, the
One image 1 and the second image 2 are all with point that is the most left in image and that go up most as zero；
(b), find in the first image 13 demarcate thing A, B, C, draw above-mentioned 3 with the rectangle of 3 10*10 to 100*100
Demarcate the bounds of thing A, B, C, and find out the center point coordinate of above-mentioned 3 rectangles(x1, y1), (x2, y2), (x3, y3)；
C () scans in the second image 2, obtain 3 corresponding to the second image 2 demarcating thing A, B, C in the first image 1
In 3 demarcation thing A ', B ', C ', same draw above-mentioned 3 demarcation thing A ', B ', C ' with the rectangle of 3 10*10 to 100*100
Bounds, find in the first image 1 demarcation thing A, B, C bounds with find in the second image 2 demarcation thing A ', B '
, C ' bounds identical, then find out the center point coordinate of above-mentioned 3 rectangles(x ' 1, y ' 1), (x ' 2, y ' 2), (x ' 3, y ' 3)；
D () sets up following relationship:
=*K
Calculate in formulaKValue,K=
E (), with 3 demarcation thing A, B, C in the first image 1 as basic point, finds out each seat of the object of motion in the second image 2
Mark(X ', Y '), according to following equation, calculate the object moved in the second image 2 corresponding to the first image (1) each coordinate(X,Y)
, i.e. by calculating X, Y coordinate
The 3rd image 3 is drawn, the second image 2 of the camera shake that has i.e. been eliminated according to these coordinates (X, Y).
The selected number demarcating thing is the most, obtainedKAccuracy can be the highest, but amount of calculation can increase accordingly,
The present embodiment, as a example by 3, actually selects 3-8 to be advisable.
Above description is explanation of the invention, is not the restriction to invention, and limited range of the present invention sees right
Requirement, in the case of the spirit of the present invention, the present invention can make any type of amendment.
