Relay contact pressure measurement method based on image identification tracking technology

The invention relates to the technical field of pressure measurement, in particular to a relay contact pressure measurement method based on an image recognition and tracking technology, which comprises the following steps of: shooting and storing a moving process of a static contact; reading the picture and carrying out noise reduction preprocessing; obtaining a relation curve graph of displacement and time; according to the relation curve graph of the displacement and the time, the variable quantity of the static contact is obtained, then the pixel value and the actual value are converted, and the actual vertical displacement L of the static contact is obtained; according to a general calculation formula of the actual transverse displacement W of the static contact and an approximate expression of Taylor expansion, the transverse displacement W of the static contact is obtained, then according to the Pythagorean theorem, the actual displacement Y of the static contact is calculated, and then according to a s
