obtained from the image processing device 120 and extracts lines of the parcel the feature point extraction unit 132 finds intersections of the extracted lines and extracts crossing points such feature extraction units compensate blurring effect and deterioration caused by shape distortion of the parcel the volume measure device 140 acquires matched junction from the two stereo images resulted from the feature extraction unit generates three dimensional model repeats error minimizing process and measure volume of the object the volume measure device 140 integrates two images obtained by the two ccd cameras and calculates volume of the parcel the volume measure device 140 includes matched junction acquiring unit 141 three dimensional model generating unit 142 error minimizing unit 143 and volume calculating unit 144 and calculated volume data is stored at the volume save device 150 the matched junction acquiring unit 141 utilizes epipolar geometry and feature points obtained by the feature extraction device 130 and acquires matched junctions of the two stereo images the three dimensional model generating unit 142 utilizes the matched junctions of the two stereo images estimates relative position of the parcel 111 and generates a three dimensional model the three dimensional model is repeatedly applied to the error minimizing unit 143 and a precise three dimensional may be obtained through these processes the volume calculating unit 144 utilizes the compensated three dimensional model and calculates exact volume of the parcel fig4 is a flow diagram illustrating parcel image recognition step of of the automatic parcel volume capture system in accordance with an embodiment of the present invention the input image device 110 detects parcel image using two ccd cameras which is indicated by.
