Method and device for controlling list interface

The invention belongs to the field of instrument positioning, and provides an instrument positioning method and device. The method comprises the steps of collecting features of a histogram of oriented gradient of an instrument; training the collected features of the histogram of oriented gradient of the instrument through a linear support vector machine, and obtaining an instrument recognition model; conducting primary positioning on the instrument on the basis of the instrument recognition model, and precisely positioning the instrument according to feature point matching. According to the method, feature points of the instrument are obtained through the histogram of oriented gradient, the instrument recognition model is obtained according to the features of the instrument, then, primary positioning is carried out on the instrument on the basis of the features of the histogram of oriented gradient, and the instrument is accurately positioned through the feature point matching.
