Patent ID: 8184157

Claim:
A method for determining an optimal sensor configuration in a vision system, comprising: a processor determining a capture quality function of an object at a plurality of locations for each of a plurality of sensor configurations, wherein the capture quality function depends non-uniformly upon an orientation of the object; for each of the plurality of sensor configurations, the processor using the capture quality function determined at the plurality of locations to determine a cost function; the processor determining an optimal sensor configuration based on the cost function determined for each of the plurality of sensor configurations; and wherein the cost function is provided by C ⁡ ( s ) = - ∫ R i ⁢ ∫ 0 2 ⁢ π ⁢ λ ⁡ ( x , θ ) ⁢ q s ⁡ ( x , θ ) ⁢ ⅆ θ ⁢ ⅆ x , wherein C(s) represents the cost function, s represents a parameter vector of a sensor, λ represents an object density, x represents a location, θ represents the orientation of the object, q s is the capture quality function, and R i represents a region associated with sensor i.
