Optical positioning apparatus and positioning method thereof
An optical positioning apparatus and method are adapted for determining a position of an object in a three-dimensional coordinate system which has a first axis, a second axis and a third axis perpendicular to one another. The optical positioning apparatus includes a host device which has a first optical sensor and a second optical sensor located along the first axis with a first distance therebetween, and a processor connected with the optical sensors, and a calibrating device placed in the sensitivity range of the optical sensors with a second distance between an origin of the second axis and a coordinate of the calibrating device projected in the second axis. The optical sensors sense the calibrating device to make the processor execute a calibrating procedure, and then sense the object to make the processor execute a positioning procedure for determining the position of the object in the three-dimensional coordinate system.
