摘　　要：提出了用高速摄影技术准确测量三维位移的新方法。该方法利用一只测量基准，使两台高速摄影机的拍摄方向相互垂直或成一定角度，并使所有的测点都在拍摄范围内。从摄影胶片上点的运动求出测点的三维坐标。实验结果表明：该方法的测量精度较高，适用于测量大位移的时间历程。A new method of measuring three-dimensional displacements using high speed cameras is described. The method utilizes a measurement frame and two high speed motion picture cameras. The cameras are so positioned that viewing directions of two cameras are orthogonal or at a definite angle, and consequently all the measuring points required are with in the photographic range. Displacements of the images of given points in the film frame from each cameras are used to determine positions in a three dimensional space. To illustrate the capabilities of this method, three examples are discussed. Very accurate results are obtained, showing that the method is suitable for measurement of large displacements.
