CIVIL-iVision

MAKERS: Eduardo Jr

A portable computer integrated with a machine vision application for an economical yet effective structural analysis is designed. This image processing device, to be called as "CIVIL-iVision", measures the maximum deflection of a concrete beam stressed under a three-point loading. This is a project of two undergrad students from the Philippines and is currently in its developing stage. CIVIL-iVision is composed mainly of the newly-released dual-core single-board computer (the Cubieboard 3 or the cubietruck) and is equipped with a high-speed and high-definition USB-connected camera and a VGA-connected LED Monitor. This is projected to benefit structural engineers and researchers from developing countries and those who cannot afford high-laboratory cost. With its features such fast-computing, higher reliability (computer vision than human vision), handiness and cost-effectiveness, this prototype is can be accurately and precisely used in building analysis such as surveying structural cracks and abnormal deflections that might be signs of flexural instability. There are certain milestones in developing the CIVIL-iVision. First, the construction of the prototype involves the proper installations of the Lubuntu 13.04 Operating System, compilers, libraries - OpenCV (Open Source Computer vision) and system requirement add-ons such as Wi-Fi and UART. Simultaneously, the concrete beam production in an experimental loading (three-point loading) needs to be started as it takes a month to finish. Then, the prototype needs to be calibrated based on the testing of the produced concrete beams using the Reaction Force Framework testing machine. Before testing, the prototype is the situated in a fixed position in a specified distance from the center of the concrete beam in which the prototype will be calibrated only in a two-dimensional view. Next, the concrete beam will be placed in the loading position. And finally, the loading of stress in the concrete beam will be in an increasing manner with respect to time. Fortunately, the testing machine will produce and display the desired output ? the maximum deflection of the concrete beam, which serves as a vital basis for calibrating the prototype. Computer vision is nothing new as it already existed since 1960s. Many of its applications were already in the market. However, the disadvantage of being immovable, which is, being fixed in a certain position may not profitable for surveying and inspections. Thus, this prototype advances in this pace.
