Abstract:
1. An automatic image-based object identification system for automatically identifying objects transported along a conveyor belt structure, said automatic image-based object identification system comprising: an object dimensioning subsystem for dimensioning each said object transported along a conveyor belt structure beneath said object dimensioning subsystem, and producing object dimension data representative of the spatial dimensions of said object with respect to a coordinate reference system; and an image-based object identification subsystem mounted above said conveyor belt structure, and having a camera control computer operably connected to said linear image formation and detection subsystem and said object dimensioning subsystem, and receiving said object dimension data from said object dimensioning subsystem and producing zoom and focus control signals for automatically controlling the variable zoom and variable focus characteristics of said linear image formation and detection subsystem as said object is transported beneath said image-based object identification subsystem; whereby a series of linear images of said object are sequentially detected by said linear image formation and detection subsystem as said object moves past said automatic image-based object identification system so that said series of linear images can be grabbed and buffered for subsequent use in constructing two-dimensional images of said object.
