  • Patent number: 7844077
    Abstract: To realize high speed and high precision with device and method of three-dimensional measurement by applying estimating process to points corresponding to feature points in a plurality of motion frame images. With the device and method of calculating location information through processes of choosing a stereo pair, relative orientation, and bundle adjustment and using corresponding points of feature points extracted from respective motion frame images, each process is made up of two stages. To the first process section (stages: 5A and 6A), robust estimation is applied to determine estimated values of calculation parameters. In the second process section (stages: 5B and 6B), corresponding points and stereo pair of large residual errors are excluded, and estimating calculation is carried out again to make measurements in three dimensions.
