Abstract:   (4557 Views)
In recent decades, close-range photogrammetry has been successfully used in various fields including industry, cultural heritage, health and civil engineering. This method as a tool for measuring deformation in industrial parts, has many advantages such as capability of real-time measurement, ease of observation, ability to achieve high accuracy and also capability of creating an archived observations for future processing. In this paper, close-range photogrammetry applied to measure a vehicle's body before and after collision to determine deformation on it. For this purpose, a measuring system is designed based on the core components of network and technical structure, taking observations, adjustment and calculation into account. Combined Photogrammetry Displacement Adjustment method (CPDA) has been applied in this research to achieve high accuracy in the measurement of displacement. The results revealed the ability of this method to achieve an accuracy of less than 1 mm in measuring the deformation of vehicle’s body. Also this method is superior to other methods in terms of cost, speed and ease of measurements.
