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.

Method and apparatus for 3D reconstruction of planes perpendicular to ground

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.

A camera calibration includes; a camera configured to acquire a first forward image from a first viewpoint and a second forward image from a second viewpoint; an event trigger module configured to determine whether to perform camera calibration; a motion estimation module configured to acquire information related to motion of a host vehicle; a three-dimensional reconstruction module configured to acquire three-dimensional coordinate values based on the first forward image and the second forward image; and a parameter estimation module configured to estimate an external parameter of the camera based on the three-dimensional coordinate values.

Camera calibration apparatus and operating method

An operating method of a slope estimating apparatus is provided. The operating method of the slope estimating apparatus including at least one camera includes obtaining a forward image through the at least one camera, detecting a lane included in the forward image, dividing the forward image into a plurality of smaller regions in a horizontal direction, identifying a plurality of lane segments included in each of the plurality of smaller regions, obtaining a plurality of coordinate values forming each of the plurality of lane segments, and obtaining a pitch angle of each of the plurality of smaller regions based on the obtained plurality of coordinate values.

Slope estimating apparatus and operating method thereof

An apparatus, system, method, and/or non-transitory computer readable media of a distance estimation apparatus including at least one camera includes obtaining a bounding box corresponding to a target vehicle on the basis of an image obtained through the at least one camera, obtaining a first rectilinear distance to the target vehicle, obtaining a first world width on the basis of the first rectilinear distance and a width of the bounding box, obtaining a second ratio of a region, corresponding to a rear surface of the target vehicle, of a region of the bounding box on the basis of a first ratio, and calculating a second world width of the target vehicle on the basis of the second ratio, wherein the first ratio represents a ratio of the rear surface and a side surface of the target vehicle.
