Abstract: An apparatus for testing an object may include a test chamber, a first chamber, a second chamber, and a gas supply module. The test chamber receives a test board for testing an object. The first chamber is under the test chamber and receives a lower surface of the test board. The second chamber surrounds the first chamber to isolate the first chamber from ambient air. The gas supply module supplies a dry gas to the second chamber to provide a positive pressure higher than an ambient pressure, thereby preventing the ambient air from infiltrating into the first chamber. Thus, during the testing of the object at a low temperature, the second chamber may prevent the humid ambient air from infiltrating into the first chamber to prevent condensation of water on the lower surface of the test board.

Abstract: An apparatus for three-dimension (3D) reconstruction includes; an event trigger module that determines whether to perform a 3D reconstruction, a motion estimation module than obtains motion information, and a reconstruction module that receives a first front image having a first view point and a second front image having a second view point, and obtains 3D coordinate values of a camera coordinate system based on the first front image and the second front image. Here, each of the first front image and the second front image includes planes, and each of the planes is perpendicular to the ground and includes feature points.
