Development and integration of a workpiece-based calibration method for an optical assistance system
Assistance systems utilize a broad range of technologies to provide information and guidance to workers in manufacturing. The use of light projectors, as of today, has seldom been catalogued in the relevant literature, and the implementation of such is yet to be found in production environments. However, light projectors may offer a cost effective enhancement for production processes, especially within the context of large-scale workpieces. Of the pertaining literature, only one calibration algorithm is currently considered applicable, thus acting as a framework of motivation for this paper. A novel calibration algorithm based on Newton’s method is presented and validated in conjunction with a proof-of-concept demonstration of the resulting accuracy, as well as the integration of such into an interface based on Node-RED, with MQTT as the main protocol.
