Claim Text:
1. A handheld device for determining at least one dimension of an object, the device comprising: a hand held device housing structure; a sensor mounted within the housing structure, the sensor receiving light from within a sensor field of view (FOV) to generate a plurality of consecutive images of the sensor FOV; a structured light source that is controllable to generate a plurality of light patterns, the structured light source mounted to the housing for movement along with the sensor and arranged to project at least one of the plurality of light patterns into the sensor FOV where at least a portion of a projected light pattern reflects from an object located within the sensor FOV and is captured by the sensor; and a processor linked to the sensor to receive images of the sensor FOV generated by the sensor, the processor programmed to control the structured light source to project a light pattern into the sensor FOV, locate the projected light pattern in at least one of the generated images, locate discontinuities in the projected light pattern and use the discontinuities to measure the at least one dimension of the object in the sensor FOV, wherein the processor is programmed to analyze the projected light pattern in at least one of the generated images and generate through computational means a subsequent projected light pattern as a function of the analysis wherein the subsequent projected light pattern is not physically pre-determined using mechanical means or pre-stored in memory.
