Abstract
The present invention provides an image recognition method whereby the influence of noise due to fluctuations of the ambient environment can be minimized and which has good response and high recognition accuracy, without using binary processing. In the image recognition of the present invention, search models where the shape and luminance value distribution of an object are modeled, are stored as image data in advance, and when multi-grayscale image data including the object is input (Step 1), the plurality of search models are distributed in the image sensing area of this input image data (Step 2), the goodness-of-fit for indicating correlation with the object is calculated for each one of the search models (Step 3), the search models are rearranged based on the goodness-of-fit (Step 5), selected (Step 6), crossed and regenerated (Step 7), and mutated and regenerated (Step 8), and through executing this genetic control, the optimum solution of the position and orientation information of the object is searched.
