Abstract
The research suggests a system that automatically generates Digital Elevation Model (DEM) of a chicken filet. The DEM is generated by close range photogrammetry methods, using stereoscopic images of the chicken filet. A major problem of the photogrammetric process is the uniformity of the chicken filet’s color and texture, which makes it hard to find matching-points in the two stereo images. The research suggests a method to enhance the accuracy of the photogrammetric process, based on the projection of a continuous multi-color pattern on the chicken filet. The projected pattern is iteratively designed based on the object's optical and textural features and on the image acquisition and projection systems color definition abilities. System measurement accuracies were within the specified limit of .5 mm in height.
