摘要： 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.

摘要： A lock, a vehicle parking system, and a vehicle parking method are provided. The lock includes a main body, a lock switch, a lock controller, a lock communication circuit, and a battery. The battery is connected to the lock switch, the lock controller, and the lock communication circuit, and configured to supply electrical energy to the lock switch, the lock controller, and the lock communication circuit. The lock communication circuit is connected to the lock controller, and transmits a locking instruction or an unlocking instruction to the lock controller when receiving the locking instruction or the unlocking instruction from a second device located outside the lock. The lock controller is connected to the lock switch connected to the main body, and the lock controller controls, when receiving the locking instruction or the unlocking instruction, the main body to perform a locking operation or an unlocking operation through the lock switch.
