What does the function find_k(gt_img, pe_img_comput, run_name) work for?

Hi, thanks for your excellent work! I wonder what the function find_k of file "preprocess_data_kitti.py" is doing?

def find_k(gt_img, pe_img_comput, run_name):
    a = (-1.65) / pe_img_comput
    b = 1.65 / gt_img
    k = b + a
    return k
