A system and method is provided for determining a speed of a belt moving along a transport axis in conveyor oven tunnel. The method includes providing a sensor module, capturing signals, processing the signals, and outputting least one speed estimate. The sensor module is disposed upon the moving belt. The sensor module includes a first optical sensor and a second optical sensor. The optical sensors are spaced apart by a distance D along the transport axis. Capturing signals includes capturing first and second signals from the first and second sensors respectively as they are transported along the belt and within the oven tunnel. Processing the signals includes determining a delay &#x394;T between the signals. The speed estimate is based upon D divided by &#x394;T.

A support apparatus for a camera and strobe lights includes a mounting plate for holding the camera substantially normal to and at a fixed distance from the photograph area, a set of legs attached to one or more portions of the apparatus providing support and positions for mounting and a set of strobe lights affixed to the legs at known positions relative to the focal plane of the camera and directed towards the photograph area to facilitate acquisition of multiple photographic images for use in one or image processing operations. The support apparatus can be automated through the use of one or more mobile strobe lights slidably coupled to each leg, capable of self-propelled linear motion along the axis of the leg and providing indication of its position along the leg to facilitate acquisition of multiple photographic images and position data for the image processing operations.
