摘要:
The present invention provides a three-dimensional image measuring apparatus and method capable of measuring projections and depressions on a surface of an object with fine precision, as well as ensuring stable convergence, even for stereo images with significant project distortion. The apparatus includes an area setting section 56 for setting a reference area 57 in one image 53 of a pair of stereo images 46 and a search area 58 in the other image 54 in a position corresponding to the reference area 57, a search image distortion correcting section 62 for applying an image distortion correction to either one of the one image 53 or the other image 54 according to the positional relationship between the reference area 57 and the search area 58 corresponding to the reference area 57, and an area shape measuring section 66 for measuring a shape of a measuring object 41 photographed in the stereo images 46 based on the reference area 57 in the one image 53 and the search area 58 in the other image 54, either one of which has been corrected by the search image distortion correcting section 62.

An image forming process for easily making an image drawing (ortho-image) in an actual place while confirming it in real time. Measuring of control points (at least three points) is performed (S110), and preparation is made for forming an ortho-image based on image data thereof and survey data. Where photographing is carried out from a plurality of directions, additional image measuring is performed (S140). Then, ortho-image formation is performed on a PC (S160). Here, if a formed ortho-image is not what is desired, ortho-image correction is performed (S180). After a satisfactory image is obtained (S200), the process moves to a next area to be measured, and the same operation is repeated. On the other hand, unless a satisfactory image is obtained, additional image measuring (S140) is performed again.
摘要:
The present invention discloses a stereo image measuring device capable of carrying out high-speed and highly reliable three-dimensional measurement for a stereo image, easily correcting any omitted measurement, measurement errors or the like, and achieving a much higher speed, efficiency and reliability for measurement as a whole. A survey instrument measures a number of control points on site. A camera is, for example a digital camera, a film camera or the like. A control point search unit executes correlation between a control point measured beforehand by the instrument survey and an image. A search area setting unit sets a search area to be used for image correlation processing based on the control points correlated by the control point search unit, and sets respective data blocks, i.e., a reference data block and a search data block. An arithmetic operation unit executes orientation calculation, and image correlation processing (stereo matching) for the search area set by the search area setting unit. A display unit is a stereo monitor, a personal computer monitor or the like providing stereoscopic vision. A measuring unit executes additional measurement when the result of correlation processing is not satisfactory.
