  • Publication number: 20250078320
    Abstract: An error correction method and device for a line structured light 3D camera. The method comprises: placing a 3D calibration plate at different positions in the field of view of the 3D camera, and allowing a relative motion to scan the 3D calibration plate to obtain multiple sets of point cloud data at different positions; processing the point cloud data and calculating corner coordinates of the 3D calibration plate corresponding to each set of point cloud data; constructing an error correction model by using an inclination angle, caused by an error, between a straight line along which the relative motion direction lies and a laser plane of the 3D camera as an error model correction parameter; calculating error correction model parameters according to a space vector constraint relationship between corner points; and applying the model to the point cloud data of a measured object to obtain distortion-free point cloud data.

  • Patent number: 9508852
    Abstract: The present invention discloses a radiation-hardened-by-design (RHBD) multi-gate device and a fabrication method thereof. The multi-gate device of the present invention includes a substrate; a source region and a drain region, which are on the substrate; a protruding fin structure and a field dielectric layer between the source region and the drain region on the substrate; a gate dielectric and a gate electrode on the fin structure and the dielectric layer; and two isolation layers separated to each other, which are disposed in the drain region between the adjacent two fins, wherein an interlayer is sandwiched between the two isolation layers.

  • Publication number: 20150014765
    Abstract: A radiation resistant CMOS device and a method for fabricating the same. The CMOS device includes a substrate, a source region, a drain region and a vertical channel on the substrate. A first dielectric protection region is inserted into the vertical channel at the center of the vertical channel to divide the vertical channel into two parts and has a height equal to the length of the vertical channel. The edge of the first dielectric protection region is 20-100 nm from an outer side of the channel, with a central axis of an silicon platform for an active region as the center. A second dielectric protection region is disposed under the source or drain region, with a length equal to the length of the source or drain region and a height of 10-50 nm. The dielectric protection regions effectively block paths for the source and drain regions collecting charges.
