so that the center of rotation is translated from the origin of coordinates back to the original position C (x0, y0), the transformation matrix is Ts 2.
5. The construction progress data entry method of the construction engineering management system according to claim 4, wherein:
after the photo finishes the sub-step of automatic tilt correction processing, an image denoising sub-step and an image smoothing sub-step are executed, and then the image denoising sub-step is stored, wherein the image denoising sub-step comprises the following steps:
detecting all connected regions in the target image, then filtering according to a threshold value of the size of the connected regions, and deleting smaller regions from the image;
the image smoothing step comprises:
when a 3 x 3 window in the image is matched with the template a, filling a window center pixel point with a foreground color; similarly, when the 3 x 3 window is matched with the template b or a template generated by rotating the template b by 90 degrees, 180 degrees and 270 degrees, filling the central pixel point of the window with foreground color; when a 3 x 3 window in the image is matched with a template c or a template generated by rotating the template c by 90 degrees, 180 degrees and 270 degrees, filling a central pixel point of the window with background color; when a 3-by-3 window in the image is matched with a template d or a template generated by rotating the template d by 90 degrees, 180 degrees and 270 degrees, filling a central pixel point of the window with background color; representing any pixel point by q, representing a foreground pixel point by 1, and representing a background pixel point by 0, wherein the expression of the template a is as follows:
q 1 q
1 0 1
q 1 q；
the expression of the template b is as follows:
q 1 q
1 0 1
0 0 1；
the expression of the template c is as follows:
0 0 q
0 1 1
0 0 1；
the expression of the template d is as follows:
0 0 0
0 1 1
0 0 q。
