Qualisys is a camera system designed initially for 3D record of body motion that is firmly marked with special points called markers. Qualisys uses infrared range of frequencies and the main advantage of the system is the fact that it records coordinates of markers and therefore the need of complicated and often not accurate image analysis is not necessary. The system was used for measuring of properties and strength of partial supporting structure of refrigerating racks and for testing of completed prototypes. Strength and deformation resistance that were specified by maximal force of safe structural changes was determined during the testing. The loading capacity of prototypes was tested using by the producer described and standardized procedure. Monitoring of deformation propagation in different components and also the completed rack was performed using the Qualisys system which allows continuous measuring over a period of loading and unloading. The results of tests enabled to verify analytically or FEM gained preliminary results of calculations easily and promptly. This work should contribute to discover utilization of alternative measuring technologies that are common in many other branches. The application of these systems may influence significantly technical complexity of some solved issues.
