VISION BASED PRESSURE SENSOR AND A WEARABLE ROBOT WITH THE SAME, CAPABLE OF DETECTING PRESSURE DESIRED TO MEASURE BY RECOGNIZING THE SIZE OF A MARKER IMAGE

摘要

PURPOSE: A vision based pressure sensor and a wearable robot with the same are provided to measure the pressure without using a strain gauge.;CONSTITUTION: A vision based pressure sensor(100) comprises a pressure receiving unit(110), a hose unit(120), an elastic unit(130), a marker unit(140), a camera unit(150), and a pressure detecting unit(160). The hose unit is formed in the pressure receiving unit and is transformed by the applied pressure. The elastic unit is formed in and end portion of the hose unit. The marker unit is formed in the elastic unit. A marker image whose size is changed according to the transformation of the elastic unit is marked on the marker unit. The camera unit photographs the marker image. The pressure detecting unit detects the pressure applied to the pressure receiving unit based on the image information of the marker image. The pressure detecting unit includes a memory unit(161) and a matching unit(162).;COPYRIGHT KIPO 2013;[Reference numerals] (160) Pressure detecting unit; (161) Memory unit; (162) Matching unit
