Abstract

This invention provides a system and method for synchronization of vision system inspection results produced by each of a plurality of processors that includes a first bank (that can be a “master” bank) containing a master vision system processor and at least one slave vision system processor. At least a second bank (that can be one of a plurality of “slave” banks) contains a master vision system processor and at least one slave vision system processor. Each vision system processor in each bank generates results from an image acquired and processed in a given inspection cycle. The inspection cycle can be based on an external trigger or other trigger signal, and it can enable some or all of the processors/banks to acquire and process images at a given time/cycle. In a given cycle. each of the multiple banks can be positioned to acquire an image of a respective region of a plurality of succeeding regions on a moving line. A synchronization process (a) generates a unique identifier and that passes a trigger signal with the unique identifier associated with the master processor in the first bank to each of the slave processor in the master bank and each of the master and slave processor and (b) receives consolidated results via the master processor of the second bank, having the unique identifier and consolidated results from the results from the first bank. The process then (c) consolidates the results for transmission to a destination if the results are complete and the unique identifier of each of the results is the same.
