一维代码优化

基于药品二进制码的一维代码优化(尽管用例适用于所有一维代码)。本用例旨在举例说明如何在一维代码应用中使用手动设置参数。

当在一幅图像中发现多个药典,且干扰区域较多,必须避免出现一些潜在的错误/阳性结果时,这种方法尤其有用。

建议程序

将 ParameterMode 设置为 30(手动设置参数)。

设置正确/必要的参数。

C1DBarCodeHeightMin(C1DBarCode 高度最小值

C1DBarCodeWidthMin

C1DNumScanlines

C1DMinIdenticalScanLines(扫描线最小值

C1DMiNCodeLength

C1DQuietZone

调整这些参数,直到只对药典进行可靠的识别。


1D code optimization based on a Pharmacode (though use case applies to all 1D codes). The goal of this use case is to give an example of using the manually set parameter for a 1D code application.

This is especially useful when multiple Pharmacodes are found in an image with many interfering zones, and a number of potential false/positive results must be avoided.

Recommended procedure

Set ParameterMode to 30 (manual setting of parameters).

Set the correct/necessary parameters.

C1DBarCodeHeightMin

C1DBarCodeWidthMin

C1DNumScanlines

C1DMinIdenticalScanLines

C1DMiNCodeLength

C1DQuietZone

Adjust these parameters until robust identification of only the Pharmacodes takes place.
