The invention discloses an image splicing method and device based on foreground and background segmentation. The method comprises the following steps: carrying out foreground and background segmentation on two images to be spliced, estimating a 2D rotation matrix between the two images according to angular velocity data acquired by a gyroscope, and estimating a gravity direction according to acceleration data when the two images are shot; preprocessing the images by using a rotation matrix between the two images, dividing the images into grids, and separately splicing the segmented foreground and background; according to requirements, the position of the final foreground in the background is calculated through the relative position of the foreground, fusion and splicing are carried out, and gravity correction can be selectively carried out on the final image. According to the method, the artifact problem occurring in the foreground and background image splicing is reduced, the excessive distortion of the edge is reduced, the dynamic foreground can be removed according to requirements, and the image splicing quality and accuracy are improved.

A biological medicine sample multi-channel friction access system comprises, from top to bottom, a sample bottle friction access mechanism, a sample bottle storage unit, an automatic sealing mechanism, a gas conveying mechanism and a transition transfer mechanism, which are sequentially arranged from top to bottom. The sample bottle friction access mechanism, the sample bottle storage unit, the automatic sealing mechanism and the gas conveying mechanism are sequentially arranged from top to bottom.

The sample bottle access driving mechanism drives the sample bottle transfer channel or the sample bottle storage channel in the sample bottle access unit to be docked with the sample bottle storage unit, or drives the sample bottle storage channel to be docked with the transition transfer mechanism. Each part constitutes a closed sample bottle storage and access system in a temperature control box. The sample bottle containing samples is stored in the sample bottle storage unit. The system realizes closed and efficient storage and batch rapid extraction of samples in an ultra-low temperature environment.

This invention discloses a deposition apparatus, including a deposition chamber with a deposition cavity inside. The deposition chamber has an inlet for single-atom or cluster particles to enter the deposition cavity, and a nozzle is provided on the inlet. The deposition cavity has a mounting position for mounting a deposition carrier, and an extraction port for connecting a vacuum pump to create a vacuum in the deposition cavity. The nozzle of this invention features a gradually decreasing inner diameter in the second cavity, accelerating the particles to form a high-speed jet, enhancing the bonding force with the deposition carrier, reducing detachment, and ensuring deposition stability and device reliability. The bottom wall, side walls, and end cap of the deposition chamber are removable and equipped with a sealing structure, facilitating sampling, cleaning, and maintenance, and reducing operational difficulty. The third groove on the mounting platform positions the carrier, and the fourth groove facilitates separation, improving ease of handling. The extraction port maintains a vacuum environment and removes unbound particles, ensuring deposition quality.
