Standards-Based Grading

Code quality grading software for fixed-mount barcode readers

基於標準的分級 (SBG) 是可在特選的 DataMan 固定式讀碼器上預先載入和啟用的軟體特徵密鑰,可將一維條碼與二維碼的品質分級。SBG 使用相同的驗證分級演算法、校準流程,以及 DataMan 驗證器一樣的使用者視窗軟體,但不包括國際標準化組織 (ISO) 方針所要求的固定角度照明。當流程控制指標 (PCM) 等現有的條碼品質軟體可靠性不足,而且不要求或無法達到 ISO 合規性時,相當適合採用 SBG。

Why Standards-Based Grading?

An increasing number of industries require compliance to ISO or industry application guidelines that can only be met with ISO-compliant barcode verifiers. However, not all applications are able to use ISO-compliant verification due to mounting restrictions or barcode placement.

SBG is the closest way to achieve reliable and repeatable barcode diagnostic results similar to verification without conforming to specific lighting angles, working distances, or mounting restrictions. With SBG, the reader can be calibrated to unify the camera’s measurement of reflectivity levels and all ISO quality parameters are reported.

Unlike SBG, PCM does not have a calibration process, follow the ISO grading algorithm requirements, or report every quality parameter. While PCM results can provide a good idea of code quality, the results can also vary significantly between setups and hardware used.

自動產生條碼品質報告

SBG 軟體平台提供視覺診斷資訊,識別條碼品質問題僅發生一次或呈現趨勢。使用 ISO 分級演算法,依照數個符號特定的品質參數量測值,指定條碼的整體等級。這些參數會測量數個影響讀碼器能否識別條碼並解碼的因素。
