Provided are a method and apparatus for detecting resistive touch panel. In order to obtain the inclination angle of a connecting line between two points, the present invention firstly calculates the resistance variance ratio of the Y plane relative to the X plane based on the voltage detection before touching and after the touching of two points; and then calculates the inclination angle based on the corresponding relationship between the inclination angle and the resistance variance ratio. In order to obtain the distance between the two points, the present invention firstly calculates the resistance variance ratio, and a first ratio of the resistance variance of any one plane of the X plane and the Y plane relative to the total resistance of the any one plane; then calculates a second ratio of an equivalent contact resistance at midpoint relative to the total resistance of the any one plane; and lastly calculates the distance between the two points based on the resistance variance ratio determined according to the corresponding relationship, the first ratio, the second ratio, and the correlated relationship of the distance between the two points. In addition, the present invention can also calculate the coordinates of the two points. |
