Abstract: The present invention relates to a light detecting and ranging (LiDAR) device for obtaining information on a distance from an object using laser light.

Abstract: A light detection and ranging (lidar) device includes: a lower base; an upper base; a laser emitting unit for emitting a laser in a form of a point light source; a nodding mirror for transforming the laser in the form of the point light source to a line beam pattern which is perpendicular to the lower base, wherein the nodding mirror reflects the laser emitted from the laser emitting unit; a polygonal mirror for transforming the line beam pattern to a plane beam pattern and receiving a laser reflected from an object; and a sensor unit for receiving the laser reflected from the object via the polygonal mirror.

Abstract: The present invention relates to a batch rendering method for two-dimensional (2D) vector graphics paths using a GPU, which may enhance the program processing speed of a game or advertisement made through HTML5 technology by utilizing 2D vector graphics batch rendering using a GPU. The present invention include gathering paths requested through an API (Application Program Interface) without immediately drawing the paths, in order to draw the paths of 2D vector graphics; drawing the gathered paths on a stencil atlas; and drawing, on a screen, quadrilaterals including the stencil atlas shape corresponding to each path in order to draw the gathered paths.
