摘要： 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.

摘要： An image processing device is provided that can precisely measure the photographing position or posture of a photographing device or the coordinates of an object based on sequentially changing photographed images. A series of sequentially photographed images are acquired, from which feature points are extracted. The feature points are tracked and correlated to each other. Stereo images are selected from the series of photographed images correlated, and subjected to an orientation and a 3D measurement. The error range of corresponding points obtained by the 3D measurement is calculated. Based on the calculated error range, it is determined whether or not the corresponding points are appropriate for 3D measurement. Those corresponding points determined as inappropriate are deleted. Another orientation and another 3D measurement are performed using those corresponding points excluding the deleted ones, thus improving the measurement precision.

摘要： With apparatus and method for measuring in three dimensions by applying an estimating process to points corresponding to feature points in a plurality of motion image frames, high speed and high accuracy are realized. The apparatus comprises: a first track determining section (4B) that determines corresponding points of feature points extracted from frames of motion images and estimates by robust estimation a coordinate transformation projection parameters between frames using part of the determined corresponding points, a second track determining section (4C) that utilizes the estimated value to determine coordinate values of estimated location of each corresponding point, to determine residuals of the coordinate values relative to the estimated values for each corresponding point, to apply threshold process, and to exclude points of large residuals as incorrect corresponding points. Three-dimensional measurement is carried out by tracking again feature points while removing those incorrect corresponding points.
