    • A model-based object recognition system operates to recognize an object on a predetermined world surface within a world space. An image of the object is acquired. This image is a distorted projection of the world space. The acquired image is processed to locate one or more local features of the image, with respect to an image coordinate system of the image. These local features are mapped a world coordinate system of the world surface, and matched to a model defined in the world coordinate system. Annotations can be arranged as desired relative to the object in the world coordinate system, and then inverse-mapped into the image coordinate system for display on a monitor in conjunction with the acquired image. Because models are defined in world coordinates, and pattern matching is also performed in world coordinates, one model definition can be used by multiple independent object recognition systems.
    • 基于模型的对象识别系统用于识别世界空间内的预定世界表面上的对象。 获取对象的图像。 这张图像是世界空间的扭曲投影。 处理所获取的图像以相对于图像的图像坐标系来定位图像的一个或多个局部特征。 这些局部特征被映射到世界表面的世界坐标系,并且与世界坐标系中定义的模型相匹配。 注释可以根据需要相对于世界坐标系中的对象进行排列,然后反向映射到图像坐标系中,以便与所获取的图像一起显示在监视器上。 因为模型是在世界坐标中定义的,并且模式匹配也在世界坐标中执行,一个模型定义可以由多个独立的对象识别系统使用。
