Drilling and sampling device for geological survey

Номер: CN116358923A
Автор: ZHANG RUI, ZHOU BAO, MA TAO, XIN QIANNAN, WEI SAILAJIA, ZHANG YONGYAN, TANG TAIBIN
Принадлежит:

The invention discloses a geological survey drilling and sampling device, which comprises a shell, a sampling hole, a sampling rod and a sampling rod, the sampling drill cylinder mechanism can horizontally move and is rotatably arranged in the shell, and the sampling drill cylinder mechanism enters and exits the shell through the sampling port; the soil scraping mechanism is telescopically arranged in the inner wall of the sampling opening and is used for scraping soil on the outer wall of the sampling drill barrel mechanism. When the sampling drill barrel mechanism retreats into the shell, the soil scraping mechanism stretches out to scrape soil on the outer wall of the sampling drill barrel mechanism, the situation that external soil is brought into the shell and affects components in the shell is avoided, and the device achieves the purpose that samples which are not disturbed as far as possible are obtained at any depth in a drill hole. The influence on detection results of physical ...

Map pre-selection method for multi-map image segmentation

Номер: CN116503623A
Автор: QIAN QINGWEN, WANG ZHE, LIU LIXIA, ZHANG YONGYAN
Принадлежит:

The invention discloses an atlas pre-selection method for multi-atlas image segmentation, and provides an atlas pre-selection method for multi-atlas image segmentation in order to solve the problem that in a multi-atlas image segmentation method, the segmentation precision of a target tissue is low due to the fact that an atlas low in similarity with a target image participates in label fusion. According to the method, a gradient convolution kernel and an intensity convolution kernel are used for carrying out convolution calculation on a registered atlas image, the intensity feature and the shape feature of the image are extracted respectively, and then the atlas is pre-selected according to the feature similarity of the atlas image and a target image. In order to verify the effectiveness of the method provided by the invention, the proposed method is tested by adopting an IXI map data set, and the result shows that after the map pre-selection method provided by the invention is introduced ...
