US Patent 10317207 Three-dimensional trace verification apparatus and method thereof

The present disclosure illustrates a three-dimensional trace verification apparatus and method thereof. The three-dimensional trace verification apparatus includes a signal emitting module and a platform module configured to maintain a fixed relative location. When a motion trace of the platform module is different from a pre-recorded trace of a trace transmitting module, the trace transmitting outputs a deviation signal according to a sensed signal. This mechanism can achieve a technical effect of automatically verifying whether the motion trace of the platform module and the pre-record trace made by a user are the same, and recording the error.
