In Colombia, coffee production sector faces several challenges, such as need increase productivity, yield, quality coffee...

In view of the fact that point cloud 3D model will be interfered by environmental factors, measurement methods and other random factors in process data scanning acquisition, there some invalid points, outliers internal noise points. this paper, a denoising method based on adaptive density clustering statistical filtering is proposed to vehicle data. which can effectively preserve features while...
