產品系列說明

  • 適用於成像系統的畸變測量及校正
  • 鈉鈣玻璃鍍鉻或象牙白玻璃鍍鉻版本
  • 隨附 NIST 精度憑證

請務必注意,雖然畸變在測量應用中通常會帶來困擾,但實際上並未遺失物體的有關資訊,而僅僅是資訊在圖像中的位置有誤。使用這些測試板,使用者可以輕鬆確定精確的畸變量,並將其排除在測量之外。在測量軟體中,可以使用相同像素連通域(或形心)分析來定位點中心。為了容納種類更多的圖像分析軟體與應用,我們提供了固定頻率與可變頻率的測試板。固定頻率測試板提供多種選項,每種都具有不同的點尺寸/點頻率組合。請依據您的視場或分辨率/精度需求選擇測試板。這類測試板提供鈉鈣玻璃鍍鉻或象牙白玻璃鍍鉻版本,以便分別納入穿透或反射型應用。套裝產品隨附含序號的 NIST 可追蹤精度憑證,符合 MIL-STD-45662A 規範。
