Description
Technical field
The utility model relates to a kind of three-dimensional measuring apparatus, is specifically related to a kind of three-dimensional measuring apparatus that utilizes shadow casting technique.
Background technology
At present, existing shadow-free 3 dimension profilometries are bilateral white light scanning survey modes.Applicant Koh Young Technology Inc., the patent No. of application is disclose following technical characterictic in the patent of 200480003759.X: the directional light of first sidelight source generation before this, the structured light that produces through grating reflects back irradiation measuring object through eyeglass a side, the opposite side light source also produces the opposite side of grating structured light through eyeglass reflection back irradiation measuring object, after grating moves, the both sides light source is scanning one by one alternately, image collecting device is images acquired successively, and the three-dimensional plot that goes out both sides through COMPUTER CALCULATION is realized shadow-free 3 dimension measurements.The bilateral scanning and measuring apparatus is realized need distinguishing when shadow-free is measured successively and is surveyed scanning in measuring object one side and another, and its Measuring Time is the twice of one-sided measurement mechanism, one-sided being measured as when gathering N and opening photo, and bilateral is measured and is needed to gather 2N and open photo.Therefore when bilateral was measured, the slow efficient of speed was low.Once more, the frequency of each sidelight grid is fixed, and can only launch the grating structured light of single-frequency, can't dynamically change during measuring, and measures very flexible.Improved for it measurement mechanism adopts the monochromatic light of the different colours of projection simultaneously from different perspectives, can realize the 3 dimension measurements of single pass shadow-free; Its structured light modulation module is in transmissive state, luminous energy about 30% is absorbed, decay to light is very big, the intensification of self is bigger, must use resistant to elevated temperatures liquid crystal cell, the simultaneous contrast is also lower, and is satisfying under certain light intensity requirement on testee surface, very high to the requirement of strength of light source.
The utility model content
The utility model is at the deficiencies in the prior art, development and Design goes out a kind of source efficiency that significantly improved, avoid structure optical modulation element temperature too high, improved the projection arrangement of multi-angle monochromatic light tripleplane measurement mechanism of the reliability and stability of projection arrangement light source.
The utility model is achieved through the following technical solutions:
Multi-angle monochromatic light tripleplane measures and uses projection arrangement, projection arrangement to comprise light-emitting device, structured light modulating part and projection lens set, and described structured light modulating part is the glass sheet that is used for transmittance structure light.
Multi-angle monochromatic light tripleplane measures and uses projection arrangement, and described glass sheet is provided with the striped that is used to form structure fringe.
