摘要

To provide a feature tracking method capable of keeping tracking a feature.SOLUTION: An image feature tracking method for tracking a feature included in an image acquired from a camera includes: a first step S1 for acquiring an image every time a sampling period SA passes, subjecting a representative image based on the images to feature searching processing for searching for a feature, and setting a searching region including the feature on the basis of the result of the feature searching processing; and a second step S2 for acquiring an image from the camera every time the sampling period SA passes, and repeatedly executing the processing for detecting a feature included in an image acquired after the representative image by using a window.SELECTED DRAWING: Figure 1
