Abstract:The goal of the project is to develop an automatic tire profile measurement system. Nowadays various commercially available sensors could be used for such distance measurements. During the project different sensors and methods for distance measurements are studied. The measurement performance depends on several factors such as physical structure of the measured object, the measurement environment and the methods to acquire information. The project is started with an analysis of the measured object where the physical structure, the form of the object, and the changes in these factors during the tire life time are considered. Three major non-destructive sensor groups are discussed in the report: optical, acoustic and imagers. According to the requirements and performance/cost factors the most suitable examples from each group of sensors is analysed and evaluated by experiments. As a result an active sensing method based on a coded light active triangulation system, consisting of a camera and a pattern projector, is chosen for the realization of a demonstrator. Finally the demonstrator is realized and extensively tested and is operational at the Laboratory for Measurements and Instrumentation.
