Handheld Three-Dimensional Thermo-Sensing System

Abstract:

Recently, three-dimensional (3D) measurement technology has achieved a high level of satisfaction in various fields such as medical and engineering fields. However, most of three-dimensional measurement systems have some disadvantages. Once the geometric configuration of the system has been determined, the configuration must be maintained until the measurements have been completed. Another disadvantage is the existence of immeasurable area that inherently exists in a single image taken from a fixed angle. In this paper, a handheld three-dimensional thermo-sensing measurement system is presented. This system is composed of a three-dimensional measurement device and a thermographic device. To realize the handy scanning measurement, 3D magnetic sensor is attached on the image capturing devices. Since the movement of the image capturing devices is detected in real-time by the magnetic sensor, the immeasurable area can be reduced by free movement of the image capturing devices. On the basis of the presented mathematical model, this system is possible to detect not only the three-dimensional shape but also the temperature distribution of an object. Experimental results show the feasibility of the measurement system.
