Nowadays virtual Instrumentation systems (Software based Instrumentation) are used in various fields, such as Business Core Transactions, Modern Cars, Automated Teller Machines (ATM), Aircraft Control Systems, Nuclear Power Plants, Manufacturing industries etc. In the modern buildings, it is very essential to predict the various parameters such as temperature, humidity, vibration, length, breadth and height accurately to control the various problems like acoustics, overload, over heat etc. The virtual Instrumentation technique is software based measurement and control system which is used to control the quality of products and processes. Here, it is proposed to identify the building parameters using various sensors. Then the signal conditioning is done by using various electronic principles. Then the analysis of various parameters is done by the software Lab VIEW. To measure the linear parameter such as Length, breadth and height of the buildings are done by using image processing technique. To identify these linear parameters, a high resolution camera is used to take a photograph of the building. Then the linear parameters are identified and analyzed using Image acquisition module which is available in Lab VIEW software. This method will give a high accurate measurement system and possess a highly reliable data and also provide a new direction in the area of building measurement.
