A gesture recognition method, apparatus and system based on coupling capacitance, which are configured to solve the technical problem in the prior art of it not being possible to recognize a complex gesture due to the fact that the coordinates of a manipulation body on a three-dimensional plane cannot be determined. The method comprises: establishing a spatial rectangular coordinate system by taking a first position point of a contact face of a capacitive touch screen as an origin; acquiring an X-axis coordinate and a Y-axis coordinate, in the spatial rectangular coordinate system, corresponding to a first sensor; acquiring the difference between a first coupling capacitance value and a second coupling capacitance value, and determining a Z-axis coordinate of at least one manipulation body in the spatial rectangular coordinate system according to the difference; and generating a movement trajectory of the at least one manipulation body according to a change in spatial coordinates of the at least one manipulation body in the spatial rectangular coordinate system, and identifying the movement trajectory to obtain a gesture recognition result.
