Background technology：
China is mining powers, and ore fragmentation shovels dress efficiency and crushing efficiency to surface mine has great influence, therefore to quick-fried
The analysis of rock fragmentation is the core procedure in explosion optimization process after broken.Now image method is mainly taken in domestic and international mine, to quick-fried
Ore fragmentation measures after broken, and the core of image analytical method is to shoot the quality of photo, be broadly divided into vertical shooting and
Level shooting is vertically shot for the best angle of shooting photo, but since surface mine place limits, is carried out using general camera
Level shooting, the photo obtained after shooting need to carry out significantly scaling processing, are converted into the photo of vertical angle shooting, picture
Cause the practical lumpiness deviation of ore fragmentation and scene on picture larger after zooming in and out, to later use software measurement ore fragmentation
Have an adverse effect.
Invention content：
In order to overcome the above problem of the existing technology, the object of the present invention is to provide a kind of plane photo angle correction ruler and
Correcting captured method.
Above-mentioned purpose is realized by following technical scheme：
A kind of plane photo angle correction ruler, composition include：The straight panel of two equal lengths is to fix with the centre position of straight panel
Point, the straight panel described in two is intersected to be fixed together in cross.
The plane photo angle corrects ruler, and two surfaces of the straight panel are coated with one group of fluorescent marker, described
One group of fluorescent marker be equally spaced centered on straight panel crosspoint, and one group of fluorescent marker is handed over using red, green color
For distribution, the red fluorescence label be with the straight panel be in 45° angle oblique line, the green fluorescent label be with it is red
Color oblique line is in the oblique line at 90 ° of angles.
The correction image processing method of above-mentioned plane photo angle correction ruler, is 1. placed on quick-fried heap surface, profit by correction ruler
It is taken pictures to quick-fried heap surface with unmanned plane, carries out preliminary calibration in shooting process by adjusting camera angle, keep two
Ruler keeps orthogonal, keeps two ruler equal lengths inside camera lens, takes pictures；2. after obtaining quick-fried heap photo, figure is used
Piece processing software zooms in and out adjustment to quick-fried heap photo site, makes two orthogonal ruler equal lengths, completes photo angle school
Just.
The correcting captured method of the plane photo angle correction ruler, the step of processing the quick-fried heap photo of acquisition
As described below:It converts quick-fried heap photo to gray level image, histogram equalization is carried out to gray level image, to the image after equalization
Morphological image reconstruction is carried out, gradient map is asked to the image after reconstruction, binaryzation is carried out to gradient map, to the image after binaryzation
Manual handle image, to image measurement and data processing, to obtain rock grain size and particle diameter distribution.
Beneficial effects of the present invention：
1. the present invention solves the limitation of angle when quick-fried heap scene is taken pictures, make shooting angle to greatest extent close to vertical.This hair
Bright structure is simple, is convenient for carrying, easy to spread, reduces the security risk during taking pictures.
The red green staggered designs of fluorescent marker in the straight panel of the present invention, and it is arranged to orthogonal oblique line, and with straight panel
It is equidistant to be symmetrical arranged centered on midpoint.Therefore, in two straight panels arranged in a crossed manner, same to level-one, the fluorescent marker of same color are oblique
Line on the same line, and forms four vertex of square.The operating personnel of unmanned plane are with the fluorescent marker corrected on ruler
Reference adjusts shooting angle so that same to level-one, four that the fluorescent marker oblique line of same color is just square push up in picture
Point, due to same level-one two oblique lines on the same line, the straight line where oblique line not at the same level will not intersect（Straight line can edge
It according to two fluorescent marker oblique lines）.During adjusting shooting angle so where the fluorescent marker oblique lines at different levels in straight panel
Straight line parallel, while ensuring two to intersect fluorescent marker oblique line at the same level in straight panels identical to the distance at center, to accurate
Obtain the shooting angle perpendicular to slope inclined-plane, the reaction of stone grain diameter dimension in the photo taken be actual proportions stone grain it is straight
Diameter.
