System for real-time measuring penetration depth of pile using 3D photogrammetry

摘要

By using the three-dimensional photogrammetric techniques intrusive amount of files according to the file represented by the three-dimensional movement amount Driven can, to measure the exact amount of penetration of the file to prevent damage to the file and pile driving apparatus, the real-time file intrusion quantity measuring system using a 3-D picture measurement is provided. Three-dimensional real-time file intrusion quantity measuring system using a photo measured according to, for measuring the amount of file intrusion amount of the pile driving intrusive measurement system file, the file is installed on the periphery of the acquisition of the images for measuring the amount of displacement of the shooting target first and second image capture device; Is attached to the file that is recorded by the recording target of the first and second image capture device; Signal generator for synchronizing the first and second image capture devices to operate at the same time; And control the first and second a focal length of the lens and the imaging angle of the image capture device, to collect the first and second two image data picked up from each of the image pickup apparatus extracts a three-dimensional spatial coordinates, the file comprising: a data processing unit for deriving a three-dimensional moving amount corresponding to the penetration amount and the rebound amount, the three-dimensional moving amount of the files is characterized in that the vertical displacement of the file, and the right and left tilt up and down the slope. ;
