DUAL-IMAGING VISION SYSTEM CAMERA, AIMER AND METHOD FOR USING THE SAME

This invention provides a vision system, typically having at least two imaging systems/image sensors that enable a multi-function unit. The first imaging system, typically a standard, on-axis optical configuration can be used for long distances and larger feature sets and the second imaging system is typically an extended-depth of focus/field (DOF) configuration. This second imaging system allows reading of smaller feature sets/objects and/or at shorter distances. The reading range of an overall (e.g.) ID-code-reading vision system is extended and relatively small objects can be accurately imaged. The extended-DOF imaging system sensor can be positioned with its longest dimension in the vertical axis. The system allows vision system processes to compute the distance from the vision system to the object to generate an autofocus setting for variable optics in the standard imaging system. A single or dual aimer can project structured light onto the object surface around the system optical axis.
