How to realize batch picture stitching on C++

This article mainly introduces C++ how to achieve batch picture stitching related knowledge, the content is detailed and easy to understand, simple and fast operation, has a certain reference value, I believe that after reading this C++ article on how to achieve batch picture stitching will have something to gain, let's take a look.

The specific code is as follows

/ * * function function: different image stitching * parameters: * vector pic_list: picture name list * int pic_cols_rows: horizontal==true,pic_cols_rows is the number of lines of the image generated horizontal==false Pic_cols_rows to generate the number of columns of the picture * bool horizontal: true- first horizontally and then vertically synthesize the picture false- first vertically and then horizontally * bool draw_rect: true- draws a rectangle on the edge of the picture false- does not draw a rectangle on the edge of the picture * * / void mergeDiffPic (vector pic_list, int pic_cols_rows, string output_file, bool horizontal=true Bool draw_rect=false) {int pic_cols = 0 Int pic_rows = 0; int max_cols=0; int max_rows=0; int size_cols=0; int size_rows=0; vector tmp_cols; vector tmp_rows; / / get the number of pictures int pic_num = pic_list.size (); vectorinput (pic_num); Mat merge; for (int iTuno; isize_cols?max_cols:size_cols); size_rows + = max_rows If ((i*pic_cols+j) > = pic_num) break;} / / create a blank image the size of size_ cols×size _ rows, which is used to display small images Size mergesize (size_cols,size_rows); merge.create (mergesize, CV_MAKETYPE (input [0] .depth (3)); / / rgb 3-channel merge = Scalar::all (0); vectortemp (pic_num) / / display the picture for (iFix I = pic_num) break;}} else {pic_rows = pic_cols_rows; pic_cols = pic_num/pic_rows; if (pic_num%pic_rows! = 0) pic_cols + = 1; int iTun0; int j = 0; for (iTun0) Max_rows [I * pic_rows+j] .cols? max_cols: input [I * pic_rows+j] .cols);} size_rows = (max_rows > size_rows?max_rows:size_rows); size_cols + = max_cols; if ((i*pic_rows+j) > = pic_num) break;} / / std::cout
