Electronic device and method for focusing and measuring points of objects

摘要

In an electronic device, an image point A on an image of an object is selected. A spectral confocal sensor is controlled to move to a position above a measuring point A′ on the object, where the measuring point A′ corresponds to the image point A, and a Z-coordinate of the measuring point A′ is computed using the spectral confocal sensor. A focal position of the measuring point A′ is computed according to the Z-coordinate of the measuring point A′, and a CCD lens is controlled to move to the focal position. The Z-coordinate of the measuring point A′ is stored into a storage unit of the electronic device.

1. A computerized method for focusing and measuring points of an object, the method being executed by at least one processor of an electronic device and comprising:
selecting an image point A on an image of the object using an input unit of the electronic device, wherein the image is displayed 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, wherein the focal position is computed by adding the Z-coordinate of the measuring point to a focal distance of the CCD lens; and storing the Z-coordinate of the measuring point A′ into a storage unit of the electronic device.
