与一维代码不同，二维代码不是在一个方向（一维）上对数据进行编码，而是在两个维度上以区域的形式进行编码。其优点是有用信息的密度更高。

CRI

显色指数

显色指数是一种光度量，是不同光源及其发射光谱范围的比较值。它是根据 16 个波长确定的，用于对色牢度进行分类。该值越高，表示照射介质再现的色彩越不失真。阳光的最高值为 100。现代白光 LED 现在的值约为 95。

执行 ROI：该 "感兴趣区域 "决定了执行 VF 搜索的区域。用户可以通过用户界面进行交互式更改，并可根据需要多次添加。无论此 ROI 添加了多少次以及重叠了多少次，所选区域始终被视为一个 ROI。此 ROI 可能包含被排除在搜索范围之外的孔洞。ROI 始终是视觉应用的一部分。

模型 ROI：该 "感兴趣区域 "用于示教过程。其形式可以是像素、区域（ROI）或带方向的区域。如有必要，也可以多次添加该区域。无论此 ROI 添加和重叠多少次，所选区域始终被视为一个 ROI。此 ROI 可能包含在示教过程中被排除的孔。根据 VF 的不同，"模型 ROI "可以是视觉应用的一部分。

1D code

One-dimensional code

Also known as barcode.

Visually readable code that represents data as binary symbols consisting of parallel bars and spaces of different widths.

2D code

Two-dimensional code

In contrast to 1D codes, 2D codes do not code the data in one direction (one-dimensional), but in the form of an area over two dimensions. The advantage is a higher density of useful information.

CRI

Color rendering index

The color rendering index is a photometric quantity and serves as a comparative value for different light sources and their emitting spectral range. It is determined on the basis of 16 wavelengths and is used to classify color fastness. The higher the value, the more undistorted the colors are reproduced by the irradiating medium. Sunlight has a maximum value of 100. Modern white LEDs now achieve a value of around 95.

DWL

Dominant wavelength

The dominant wavelength specifies at which wavelength a lamp emits with maximum intensity. Sometimes to be taken into account for photobiological safety.

FOV

Field of view

Image acquisition area of a camera. With regard to photobiological safety, it additionally preserves the importance of the field of view with regard to the different exposure durations of the risk classes.

HMI

PV

Process variable

ROI

Region of interest

The "region of interest" within an FOV. If required, this can be defined separately in order to restrict search criteria to a defined region and not to use the complete image acquisition area of the camera.

Execute ROI: This "region of interest" determines the area in which the VF search is executed. This can be changed interactively by the user via the user interface and added as many times as needed. Regardless of how many times this ROI is added and overlaps, the selected region is always considered an ROI. This ROI may contain holes that are excluded from the search. The ROI is always part of the vision application.

Model ROI: This "region of interest" is used for the teach-in process. It can be in the form of a pixel, region (ROI) or region with direction. This region can also be added multiple times if necessary. Regardless of how many times this ROI is added and overlaps, the selected region is always considered an ROI. This ROI may contain holes that are excluded during teach-in. Depending on the VF, the "Model ROI" can be part of the vision application.

The ROI is created using an ROI tool. "ROI" refers to the region used by Halcon. "ROI tool" refers to the graphical representation used by the user in the HMI application to create/modify the ROI itself.

For the onboard LED illumination of the Smart Camera, the integration time is also the exposure time of the LEDs.

Parameters

Parameters are settings. Most parameters are typically determined using a "teach-in process" (analogous to autotuning for axes).

Each vision function consists of a fixed set of parameters.

Vision parameters: Parameters that are transferred acyclically and stored in the vision application configuration. They describe generic Halcon parameters. Users can view the vision parameters in the user interface and under certain conditions edit them. These parameters are always part of the vision application.

Model parameters: Describes parameters that are available for a specific model. They define one parameter set per model. Model parameters can be divided into types to define different parameter sets per model. One special type of model is a link type, which can be used to link together models that have already been taught. These parameters are always part of the vision application.
