Patent ID: 6970593

Claim:
A stereo image processing apparatus subjecting first image data obtained from a first flying object (airframe) during a first time period to stereo matching processing to generate first three-dimensional data and subjecting second image data obtained from a second flying object during a second time period different from said first time period to stereo matching processing to generate second three-dimensional data, comprising: data correcting means for correcting erroneous data corrected including at least noises and losses in inputted three-dimensional data by using information of external shapes of buildings obtained from map data, said data correcting means inputting said first three-dimensional data to provide first modified three-dimensional data and inputting said second three-dimensional data to provide second modified three-dimensional data; map data storing means for storing said map data; data storing means for storing said first modified three-dimensional data; data comparing means for comparing said first modified three-dimensional data stored in said data storing means with said second modified three-dimensional data; and map data modifying means for modifying said map data stored in said map data storing means based on differential information obtained from said data comparing means to provide modified two-dimensional map data.
