Abstract: The present disclosure relates to a method of controlling a 3D printer for construction which prints and forms various structures, in which a controller 10 configured to control the 3D printer for construction, a scanner 30 configured to detect stereographic surface information, and a computer 40 connected to the controller 10 and the scanner 30 are provided so that the scanner 30 detects actually measured surface information 39 of a printing matter 20 and transmits the detected actually measured surface information 39 to the computer 40, and the computer 40 compares the actually measured surface information 39 with planned surface information 49 to calculate a printing error and then corrects command information 19 such that the printing error is compensated for and transmits the corrected command information 19 to the controller 10.

Abstract: Disclosed herein is an image processing apparatus of a vehicle camera, including a light source extraction unit configured to extract light sources from a first frame exposed to light sources during a first time and to extract light sources including motion blurs from a second frame exposed to the light sources during a second time longer than the first time, a target light source classification unit configured to classify a first target light source that belongs to the light sources of the first frame and that does not move and a second target light source that belongs to the light sources of the second frame and that does not move, and a motion determination unit configured to estimate a first location that is the central point of the first target light source and a second location that is the central line including the central point of the second target light source, compare the first location with the second location, and determine whether or not a pitch motion of the vehicle has occurred.

Abstract: The present invention provides a biofilm reactor comprising a spiral structure and a water treatment facility using the same. The biofilm reactor comprises an inlet pipe for supplying water, an air supply pipe for supplying air, and an outlet pipe for discharging the water and air that passed through the reactor, wherein the reactor is provided therein with a spiral structure for forming a spiral bubble flow passage from the air supply pipe to the outlet pipe such that the oxygen transfer rate is increased by inducing the flow of bubbles supplied from the air supply pipe and by increasing residence time of the bubbles.
