    摘要: A method of finding targets in a color image applies ratio space rich colored filtering to identify a band of pixels that form a transition zone from one rich color to another. This pixel band is reduced to a rich color transition curve. A set of transition curves with simple geometric and color properties for the entire image, can be compared to a database of target properties to identify a target in an image.

    摘要: A method for identifying color in a target creates a ratio color space by determining the largest color component value of each pixel in an image and creating a ratio of all of the color component value with the largest component value for each pixel. The ratio for the color component of each pixel undergoes a threshold test to identify each color component as a rich shade or a fade shade. The ratio space color components are converted to a black and white image. Color information of adjacent pixels are clumped together to form blobs of the same color. The blobs are filtered by shape, color, location, or orientation and sorted to find targets that consist of a predefined pattern with the desired characteristics.

    摘要: A method and apparatus for tracking a location of an object or target in a 3D space. At least one target including unique sub-targets is attached to a vision object in the 3D space. A camera disposed in a 3D space, and coupled to a computing device captures a 2D image of a target. The camera computing device identifies the sub-targets of the target and transfers the sub-target data to a computing device associated with the camera which accesses a data base of target data to identify target an, using sub-target separation distances in the database to determine 3D location and orientation of the target. Another computing device transforms the 3D locations of the detected target in the camera coordinate system into a single 3D coordinate system for the 3D space. The 3D location of targets detected by multiple cameras of different computing devices maybe daisy chained together to convert the target location in the 3D coordinate systems of each computing device into a single 3D coordinate system.
