摘要： The present application provides a method and a system for detecting data of an instrument. The method comprises controlling rotation of the current data image in a first direction and acquiring current projection values of a pointer of the instrument in a vertical direction from the current data image after acquiring a current data image from an instrument to be read; then, selecting a maximum projection value from the acquired projection values and determining a corresponding position of the pointer of the instrument as a position to be calculated; calculating a first rotation angle required by rotation of the pointer of the instrument to the position to be calculated; substituting the first rotation angle into a pre-stored first calculation formula and calculating a first angle between the pointer of the instrument and the position to be calculated; then, substituting the first angle into a formula of correspondence between a pre-stored angle between the pointer of the instrument and the position to be calculated and instrument graduations to calculate current instrument data of the instrument to be read, thus ensuring the accuracy of the resulting data under various conditions.
