与机器视觉产品相关的 mapp 视觉技术包提供了一系列视觉功能。每种功能都由一组参数组成,针对特定用途提供相应的功能范围。
信息:
来自 MVTec 的 HALCON 机器视觉库已集成到 mapp Vision 中。其算法久经考验,可为位置检测、完整性检查、质量评估、测量和识别提供稳健、高性能的解决方案。
根据所使用的相机硬件,一个应用可同时使用一个视觉功能(智能传感器)或多个视觉功能(智能相机)。
摄像机的默认配置和每个视觉功能的参数设置都是通过为各个视觉功能描述的寄存器来设置的。这些寄存器可在 Automation Studio 中按如下方式访问:
循环参数和常规数据点可通过摄像机的 I/O 映射进行访问。它们可在运行时修改。
循环摄像机参数可通过摄像机配置访问。运行时无法修改。
循环视觉功能参数通过 mapp Vision HMI 应用程序进行配置。
循环参数也可在 mapp Vision HMI 应用程序中作为视觉功能的过程变量进行访问。
非循环参数分为几个子类别:
常数: 有助于确定 POWERLINK 帧的长度,只能在 Automation Studio 中配置时修改(即非循环)。
视觉参数: 视觉功能的配置参数。
模型参数: 模型的配置参数。这些参数直接决定了模型的大小(因此也决定了模型所包含的数据量)。
信息:
视觉功能的模型总是与特定的 mapp Vision 版本结合使用,不能向后兼容!

The mapp Vision Technology Package associated with machine vision products provides a range of vision functions. Each is a group of parameters that offer the corresponding range of functions for a particular purpose.
Information:
The HALCON machine vision library from MVTec was integrated into mapp Vision. The well proven algorithms enable robust, high-performance solutions for position detection, completeness inspection, quality evaluation, measuring and identification.
Depending on the camera hardware used, either one vision function (for a Smart Sensor) or several vision functions (for a Smart Camera) are used simultaneously for an application.
The default configuration of a camera and parameter settings for each vision function are set using the registers described for the individual vision functions. The registers can be accessed in Automation Studio as follows:
•Cyclic parameters and general data points are accessible via the I/O mapping of the camera. They can be modified at runtime.
•Acyclic camera parameters are accessible via the camera configuration. They cannot be modified at runtime.
•Acyclic vision function parameters are configured using the mapp Vision HMI application.
Cyclic parameters are also accessible in the mapp Vision HMI application as process variables of the vision function.
Acyclic parameters are divided into several subcategories:
•Constants: Help to determine the length of a POWERLINK frame and can only be modified during configuration in Automation Studio (i.e. acyclically).
•Vision parameters: Configuration parameters of the vision function.
•Model parameters: Configuration parameters of a model. These directly determine the size of the model (and therefore the amount of data it contains).
Models of a vision function are always taught-in with a specific mapp Vision version and are not backward compatible!
