Abstract: In a method of predicting a position of an object at a future time point for a vehicle, video image information at a current time point and at a plurality of time points before the current time point acquired through a camera of the vehicle may be extracted as semantic segmentation image. A mask image imaging an attribute and position information of an object present in each of the video images may be extracted. A position distribution of the object may be predicted by deriving a plurality of hypotheses for a position of the object at a future time point through deep learning by receiving video images at the current time point and the time points before the current time point, a plurality of semantic segmentation images, a plurality of mask images, and ego-motion information of the vehicle, and calculating the plurality of hypotheses as a Gaussian mixture probability distribution.

Abstract: Provided is a wire saw (1) that cuts an ingot (I) while swinging the ingot. The wire saw (1) includes a first driving block (100), a second driving block (110), and an ingot holder (120). When the first driving block (100) moves, the second driving block (110) moves in a direction perpendicular to a moving direction of the first driving block (100), and simultaneously the ingot holder (120) is swung. The ingot holder (120) is transferred to a z-axial direction in which the ingot is cut by a lifting block (73), and the lifting block (73) moves independently of the first or second driving block (100 or 1110). Thus, the ingot (I) can be swung separately from the lifting block (73), and be inhibited from moving left and right. Since only the first driving block (100) is controlled, easy control and a simple structure are provided.
