        {'ocr': 'SL593LM', 'ocr_conf': 99, 'ltrb': [819, 628, 1085, 694], 'ltrb_conf': 90}
        ], 
    'ltrb_proc_sec': 0.22, 
    'ocr_proc_sec': 0.15
}

{
    'results': [
        {'ocr': '123가4568', 'ocr_conf': 99, 'ltrb': [181, 48, 789, 186], 'ltrb_conf': 83}, 
        {'ocr': '123가4568', 'ocr_conf': 99, 'ltrb': [154, 413, 774, 557], 'ltrb_conf': 82},
