Abstract: Described are machine vision systems, methods, and apparatus, including computer program products for associating codes with objects. In an embodiment, a machine vision system includes an area-scan camera having a field of view (FOV), the area-scan camera disposed relative to a first workspace such that the FOV covers at least a portion of the first workspace and a dimensioner disposed relative to a second workspace. The machine vision system includes a machine vision processor configured to: determine an image location of a code in an image; determine a ray in a shared coordinate space that is a back-projection of the image location of the code; determine one or more surfaces of one or more objects based on dimensioning data; determine a first surface of the one or more surfaces that intersects the 3D ray; and associate the code with an object associated with the first surface.
Abstract translation: 描述的是机器视觉系统，方法和装置，包括用于将代码与对象相关联的计算机程序产品。 在一个实施例中，机器视觉系统包括具有视场（FOV）的区域扫描照相机，相对于第一工作空间设置的区域扫描照相机，使得FOV覆盖第一工作空间的至少一部分，以及尺寸 相对于第二工作空间布置。 机器视觉系统包括机器视觉处理器，其被配置为：确定图像中的代码的图像位置; 确定作为代码的图像位置的反投影的共享坐标空间中的射线; 基于尺寸数据确定一个或多个对象的一个或多个表面; 确定与3D射线相交的一个或多个表面的第一表面; 并将代码与与第一表面相关联的对象相关联。
