Electronic device and method for focusing and measuring points of objects

An electronic device, comprising:

• an input unit;
• a display unit;
• a non-transitory storage medium;
• at least one processor;
• and
• one or more modules that are stored in the non-transitory storage medium;
• and are executed by the at least one processor, the one or more modules comprising instructions to:
• select an image point A on an image of the object using the input unit, wherein the image is display on the display unit;
• control a spectral confocal sensor to move to a position above a measuring point A′ on the object and to compute a Z-coordinate of the measuring point A′ using the spectral confocal sensor, wherein the measuring point A′ corresponds to the image point A;
• compute a focal position of the measuring point A′ according to the Z-coordinate of the measuring point A′, and controlling a CCD lens to move to the focal position;
• and
• store the Z-coordinate of the measuring point A′ into a storage unit of the electronic device.

A non-transitory storage medium having stored thereon instructions that, when executed by a processor of an electronic device, causes the processor to perform a method for focusing and measuring points of an object, comprising:

• selecting an image point A on an image of the object using an input unit of the electronic device, wherein the image is display on an display unit of the electronic device;
• controlling a spectral confocal sensor to move to a position above a measuring point A′ on the object and to compute a Z-coordinate of the measuring point A′ using the spectral confocal sensor, wherein the measuring point A′ corresponds to the image point A;
• computing a focal position of the measuring point A′ according to the Z-coordinate of the measuring point A′, and controlling a CCD lens to move to the focal position;
• and
• storing the Z-coordinate of the measuring point A′ into a storage unit of the electronic device.
