Abstract

A scan conversion apparatus using a graphics processing unit (GPU) is proposed. The scan conversion apparatus may include an input unit that receives an input of N-th azimuth information (N is a natural number) of a radar, and a controller. The controller may check the sampling number of the inputted N-th azimuth information, and compare the checked sampling number of the N-th azimuth information with the sampling number of a preset scan conversion to determine whether to perform additional sampling. The controller may also perform additional sampling through a GPU according to a determined result, and generate a texture map by using the N-th azimuth information which is additionally sampled or not additionally sampled. The controller may further draw an N-th triangular shape on the basis of the center coordinates of a circle through the GPU, and then perform a scan conversion on the texture map by texture mapping.

Dependent claims

A scan conversion apparatus using a graphics processing unit (GPU), comprising:

an input unit configured to receive N-th azimuth information of a radar sampled with a sampling number, wherein N is a natural number;
and
a controller comprising a central processing unit (CPU) and the GPU and configured to:
identify, using the CPU, the sampling number of the received N-th azimuth information;
compare, using the CPU, the identified sampling number of the received N-th azimuth information with a predetermined sampling number of a scan conversion;
in response to determination that the identified sampling number is different from the predetermined sampling number, perform, using the GPU, the additional sampling on the received N-th azimuth information;
generate, using the CPU, a texture map based on the additionally sampled N-th azimuth information;
generate, using the GPU, an N-th triangle based on a center coordinate of a circle;
and
perform, using the GPU, the scan conversion by texture-mapping the texture map.
