Benefits of technology

The present invention provides a system and method for calibrating a 3-D projection printing system using both ways of look-up table and interpolation method. The invention also includes a portable calibration fixture system and a flexible 3-D projection printing system to improve calibration precision, facilitate calibration and printing operations, increase printing effect, and save cost.

Problems solved by technology

Such system is applied to the field of 3-D printing very often, and the printing quality cannot be assured if aforesaid conditions do occur.
Hence, an advanced 3-D projection system with an advanced calibration method are deemed to be a developed issue to the people skilled in the art.

Embodiment Construction

[0014]Following preferred embodiments and figures will be described in detail so as to achieve aforesaid objects.

[0015]According to FIG. 7, which illustrates a schematic view of a calibration projection system. The system includes a projector 51, a diffuser 53, a reflection mirror 55, a camera 56, and a computer 57. The projector 51 projects a projected image 54 onto the diffuser 53. The projected image 54 goes through the diffuser 53, and then to the reflection mirror 55. The reflection mirror 55 reflects the projected image 54 to the camera 56. The camera 56 captures the reflected projected image 54. Continuously, the captured image in the camera 56 is digitized and sent to the computer 57 via WIFI, USB, Bluetooth, cable, or the other wireless / wired methods.

[0016]Please refer to FIGS. 1A˜1B, FIGS. 2-1˜4, FIGS. 3-1˜5, and FIG. 4, which illustrate a flow chart, plural practical views of calibration fixture steps, plural practical views of calibration projection steps, and a schemati...

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention generally relates to a method for a 3-D projection printing system and a system thereof, more particularly to a system adopts both the ways of look-up table and interpolation method to calibrate.2. Description of the Prior Art[0002]In case the lens of the projector is malfunctioned or deformed by some reasons as hot environment, falling down, etc., and / or the whole system happens tolerances while in assembly, the precisions for the system may not exist. Such system is applied to the field of 3-D printing very often, and the printing quality cannot be assured if aforesaid conditions do occur. Hence, an advanced 3-D projection system with an advanced calibration method are deemed to be a developed issue to the people skilled in the art.SUMMARY OF THE INVENTION[0003]One embodiment of the method for a 3-D projection printing system comprises the steps of: the 3-D projection printing system capturing a light-...
