Abstract: A method and apparatus for decoding codes applied to objects for use with an image sensor that includes a two dimensional field of view (FOV), the method including the steps of providing a processor programmed to perform the steps of obtaining an image of the FOV, attempting to decode a code candidate in the image using a first decode algorithm, and where the attempt to decode the code candidate fails, maintaining the image in memory. The method including repeating the above steps until one of a threshold number of attempts to decode the code candidate have failed and the code candidate has been successfully decoded. Further, the method includes accessing the images maintained in memory and attempting to decode the code candidate in at least a subset of the images stored in memory using a second decode algorithm that is different than the first decode algorithm.

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: Systems and methods for contiguously and accurately updating target object information during an entire target engagement period are provided. The target tracking system includes a database for storing starfield information, an optical beam source configured to illuminate one or more optical beam pulses, first and second camera systems, and a processor. The processor instructs the first camera system to track the object based on recordation of the tracked object, instructs the second camera system to stabilize the tracking image based on the instructions sent to the first camera system, and determines inertial reference information of the tracked object based on the stabilized image and starfield information associated with the stabilized image.
