These parameters need to be modified
NUMBER_INPUTFILES number of files
INPUT_FILENAMES file name (multiple file names are separated by '|')
OUTPUT_FILENAME output file name
OUTPUT_STITCHED_FILENAME This line belongs to the output path of the process file. Although NO is selected, it will still output to you when calling in batches , it is recommended to delete this line (does not affect the operation of the program)
