Embodiment
[0037] Such as Figure 4 As shown, the embodiment of the present invention provides an optical tracking 3D scanner wireless synchronization trigger system, the system includes a master wireless synchronization device and a plurality of slave wireless synchronization devices working in the same frequency band, the master wireless synchronization device and all The multiple slave wireless synchronization devices are connected through wireless communication. In the same space, multiple wireless synchronization trigger systems can work simultaneously in different wireless frequency bands.
[0038] The master wireless synchronization device first sends a PWM synchronization signal with a fixed frequency and duty cycle to the slave wireless synchronization device, and the slave wireless synchronization device automatically adjusts its output according to the PWM synchronization signal to ensure that the output of the two is the same synchronization signal . Moreover, the error bet...
