Abstract
A portable, handheld system for target measurement is provided. The system comprises an imaging assembly comprising first and second camera sensors, separated from one another by a fixed separation distance; and a processor operably coupled to the imaging assembly, the processor being configured to: activate the imaging assembly to capture a primary image of the target with the first camera sensor and to capture a secondary image of the target with the second camera sensor, wherein the target is in a field of view of each of the first and second camera sensors; analyze the captured primary and secondary images to determine a pixel shift value for the target; calculate a parallax value between the primary and secondary images using the determined pixel shift value; compute measurement data related to the target based on the calculated parallax value; and output the measurement data to a display of the imaging system.
