openALPR 无法扫描 eu2 车牌

Question

我在 C# 中使用 openALPR 库，这是我的 .config 文件我已经对我的板进行了培训，但它无法识别孔板。我试过在调试模式下执行。扫描结果没有任何错误，但第一行无法识别

; One-line European style plates

; 35-50; 45-60, 55-70, 65-80, 75-90
char_analysis_min_pct = 0.30
char_analysis_height_range = 0.20
char_analysis_height_step_size = 0.10
char_analysis_height_num_steps = 5

segmentation_min_speckle_height_percent = 0.15
segmentation_min_box_width_px = 5
segmentation_min_charheight_percent = 0.2;
segmentation_max_segment_width_percent_vs_average = 1.65;


plate_width_mm = 141
plate_height_mm = 121

multiline = 1

char_whitespace_between_lines_mm = 10

char_height_mm = 43;80
char_width_mm = 25;53
char_height_mm = 43;80
char_width_mm = 25;53

char_whitespace_top_mm = 12.5
char_whitespace_bot_mm = 12.5

template_max_width_px = 423
template_max_height_px = 363
#template_max_width_px = 117
#template_max_height_px = 65

; Higher sensitivity means less lines
plateline_sensitivity_vertical = 55
plateline_sensitivity_horizontal = 55

; Regions smaller than this will be disqualified
min_plate_size_width_px = 14
min_plate_size_height_px = 12

; Results with fewer or more characters will be discarded
postprocess_min_characters = 6
postprocess_max_characters = 12

detector_file = eu2b.xml
ocr_language = ita

; Override for postprocess letters/numbers regex. 
postprocess_regex_letters = [A-Z]
postprocess_regex_numbers = [0-9]


; Whether the plate is always dark letters on light background, light     letters on dark background, or both
; value can be either always, never, or auto
invert = auto
