Abstract
The invention provides a control method, device and system. An image acquisition controller receives current from a trigger sensor and judges whether the current is greater than preset current or not to obtain a comparison result, and the image acquisition controller controls an image acquisition device to be switched from a low power consumption state to an image acquisition state if the comparison result indicates that the current is greater than the preset current. Due to the fact that the trigger sensor produces current when the distance between a target and the image acquisition device is smaller than a preset numerical value, the image acquisition device does not need to perform periodic scan and can operate in the low power consumption state under the condition that no target is close to, and power consumption can be reduced.
