    Abstract: Disclosed herein is a 3D distance measurement system. The 3D distance measurement system includes an image projection device for projecting a pattern image including one or more patterns on a target object, and an image acquisition device for acquiring a projected pattern image, analyzing the projected pattern image using the patterns, and then reconstructing a 3D image. Each of the patterns includes one or more preset identification factors so that the patterns can be uniquely recognized, and each of the identification factors is one of a point, a line, and a surface, or a combination of two or more of a point, a line, and a surface. The 3D distance measurement system is advantageous in that it reconstructs a 3D image using a single pattern image, thus greatly improving processing speed and the utilization of a storage space and enabling a 3D image to be accurately reconstructed.

  • Patent number: 7916932
    Abstract: A 3D depth imaging method and system are disclosed. The 3D depth imaging method involves radiating light at a measurement target object using a projection means and imaging the light using an image receiving means, and includes the steps of assigning a unique transmitting side address to a signal corresponding to each pixel of the projection means to encode the signal; projecting multiple light patterns at the projection means to transmit the signal; receiving the encoded signal at the image receiving means; separating the received signal to restore the address; and determining a pixel position of the object using the transmitting side address and the restored address. With the 3D depth imaging method and system, it is possible to exactly separate signals received by the image receiving means even when the signals are overlap and the geometrical structure of the object varies, and it is also possible to obtain a depth image that is robust against ambient environmental noise.

  • Patent number: 7588320
    Abstract: Disclosed are a droplet ejection device and method using an electrostatic field. The droplet ejection method includes: setting a separate electric field direction in each of a plurality of nozzles; supplying one of ink and ink containing particles to each nozzle; and forming and ejecting a plurality of separate ink droplets. The droplet ejection device includes a deposition part having electrode layers and insulating layers deposited toward a nozzle. Therefore, it is possible to readily perform droplet ejection without a heater or diaphragm vibration device. In addition, it is possible to reduce impact applied to the ink and obtain good print quality, since the ink is ejected using the electrostatic field.
