Paper Abstract

For volume contour visual measurement, multi measurement units and multi space images mosaic are needed to achieve the whole task. With the location information of pre-designed feature points, coordinate systems of multi-measurement units can be transformed and integrated conveniently and validly. So the identification and location of pre-designed feature points are the key technologies for space image mosaic and volume contour measurement. In this paper, an identification and location technology based on the invariable curve-moment and least-square ellipse fitting is proposed. The method can be used to identify and locate pre-designed targets with high precision automatically and has strong robustness. In the experiment, the location precision is less than 0.05 pixels and the fractional error of 3D space distance excels 0.56%.
