The invention discloses a touch track recognition method and device, equipment and a storage medium, and relates to the technical field of computers. The method comprises the following steps: determining a target window duration of a sliding window according to a current use parameter of the mobile smart screen, and inputting a touch sampling point sequence into the sliding window; generating an initial trajectory form through clustering based on a plurality of continuous window data, and judging whether the initial trajectory form has jitter or not by comparing the actual length-width ratio of the initial trajectory form with a length-width ratio threshold value; determining a target control point corresponding to the initial trajectory form by using a control point determination rule corresponding to the jitter judgment result, and determining a target smoothing coefficient according to the current height of the mobile smart screen; and smoothing the target control point by using the target smoothing coefficient. By integrating the influence of the height of the mobile smart screen on touch track recognition, a touch track filtering scheme of the mobile smart screen at different heights is dynamically adapted without depending on a hardware sensor, and the accuracy of touch track recognition is improved.
