A master-slave system includes a master and a slave. The master includes a first communication interface, a master controller, and a voltage meter. The voltage meter is connected to the first communication interface and the master controller. The slave includes a second communication interface, an input unit, a slave controller, and a control indicator unit. The control indicator unit is connected to the second communication interface and the slave controller. The salve controller controls voltage of a node between the control indicator unit and the second communication interface to change between a high logic level and a low logic level according to signals from the input unit. The voltage meter is connected to the control indicator unit to detect the voltage of the node. The master controller controls the master to execute a function according to change of the obtained voltage within a preset period.

Master-slave system with reversible control direction function

A method for measuring size of an object is provided. The method includes controlling a distance measurement unit to measure a vertical distance between an electronic device and the object in response to a measurement operation, controlling an image capturing unit to capture an image in front of the electronic device, which includes an image of the object in response to the measurement operation. Computing an actual size of the captured area according to the distance measured by the distance measurement unit and an angle of view of the image capturing unit. In addition, obtaining the image of the object from the captured image, and further computing the proportion of the image of the object in the captured image. Then computing the size of the object according to the proportion and the actual size of the captured area, and displaying the measured size of the object.
