Claim One:
1. A method of measuring a height of a location on an object, comprising: projecting at least one line of radiation onto the object using at least one illumination source, wherein the object is placed on the surface of a workstation; detecting at least one line of radiation reflected from the object including semi-transparent surface using at least one image capturing unit comprising at least one sensor and at least one camera; and generating at least one two-dimensional height displacement map from the detected line of radiation, wherein the two-dimensional height displacement map comprises a plurality of spots using at least one processing unit; and processing the intensity of each spot of the plurality of spots as a gray-scale using a two-dimensional image processing technique to calculate the height of the object at each spot; the height of the object is calculated by following formula: 
 Object height=Height of sensor/( x cosine(90 degree−(laser angle+camera angle)))/cosine(laser angle), wherein height of sensor signifies the height to the y-location of the pixel with maximum intensity on the sensor; wherein x represents the x position on the two-dimensional height displacement map; wherein laser angle is angle between the laser beam and a line drawn from the object, wherein the line drawn is perpendicular to the planar surface of the workstation; wherein camera angle is angle between a reflected ray and a line drawn from the object, wherein the line drawn is perpendicular to the planar surface of the workstation; and wherein the reflected ray is at least one line of radiation reflected from the object.
