【Abstract】 Traditional surveying method has lots of disadvantages,such as great workload, low efficiency, high cost and low precision. This paper presents a surveying method of close-range photogrammetry based on non-metric digital camera. The surveying method calculates objects, spatial 3-D(dimension) coordinates by direct linear transformation(DLT), and the method is analyzed by a real example of deformation monitoring of buildings. The paper concludes that the method can get high precision and measure building deformation effectively.更多还原
