MULTI-CAMERA SYSTEM FOR DETERMINING COMPLEX-SHAPE FRUIT SIZE

Annotation

The structure of an optoelectronic system for ensuring the separation of fruits of complex shape according to their geometric parameters is proposed. A genetic algorithm developed to solve the problem of optimizing location of the video cameras in the corresponding segments of space according to the criterion of ensuring the required error in determining the fruit shape is described and tested. Simulation modeling of the system performance with four video cameras shows that for restoring the shape of fruits with an error of 18 microns, it is sufficient to use a population of 30 individuals in the genetic algorithm. Parameters of spatial orientation of the four video cameras located at a distance of 500 mm from the fruit are found for estimated error of 3.5 μm in restoring three-dimensional coordinates of the points on the fruit surface.
