Touch coordinate acquisition method and device, equipment and storage medium

The invention discloses a touch coordinate obtaining method, device and equipment and a storage medium, the touch coordinate obtaining method comprises the steps that a deviation matrix is obtained based on a circular touch signal generated by finger pressing and a reference matrix, each row and each column in the reference matrix comprise 1 + 2n nodes, n is the number of turns of a contact piece, and n is the number of turns of the contact piece; each node corresponds to a node circular area generated by an original touch signal; obtaining a node square area corresponding to each node based on the area calculation formula corresponding to each node and the node circular area; based on the square area of each node, obtaining a maximum area node; and obtaining a touch absolute coordinate corresponding to the maximum area node on the circular touch inductor by adopting a touch gravity center algorithm. According to the method, multi-point touch of the self-capacitance touch IC on the circular touch screen can b
