Abstract
A handheld device and method using the device, the device comprising a sensor receiving light from within a field of view (FOV) to generate a plurality of consecutive images of the FOV, a structured light source that is controllable to generate a plurality of light patterns, the source arranged to project at least one light patterns into the FOV where at least a portion of a pattern reflects from an object and is captured by the sensor and a processor to receive images, the processor programmed to control the source to project a pattern into the FOV, locate the pattern in at least one of the generated images, locate discontinuities in the pattern and use the discontinuities to measure at least one dimension.
