Abstract: Disclosed are a point cloud model processing method and apparatus, and a readable storage medium. The method includes: acquiring a target image pair and first and second neighborhood images corresponding to the target image pair from first and second image sets photographed for a target scene with different visual effects; performing a calculation to obtain a merge parameter based on the relationship among the target image pair, the first neighborhood image, the second neighborhood image, a first point cloud model, and a second point cloud model; and merging the first point cloud model and the second point cloud model based on the merge parameter to obtain a target point cloud model for reconstructing a three-dimensional structure of the target scene.

Abstract: A sample processing apparatus (100) and a use method therefor. The sample processing apparatus (100) comprises a uniform mixing mechanism (130) and a magnetic attraction mechanism (140). The sample processing apparatus (100) further comprises at least one of a sample tube (110) and a reaction tube (120). The uniform mixing mechanism (130) is configured to perform uniform mixing processing on a biological sample in the sample tube (110) and/or a biological sample in the reaction tube (120). The magnetic attraction mechanism (140) comprises a magnet (141). The magnet (141) can move relative to the sample tube (110) and/or the reaction tube (120), so as to perform magnetic attraction processing on the biological sample in the sample tube (110) and/or the biological sample in the reaction tube (120).

Abstract: An automatic extraction device and a use method therefor. The automatic extraction device comprises a sample processing apparatus (100), a portal frame (200), a consumable assembly (300), and a pipetting apparatus (400). The sample processing apparatus (100) comprises a uniform mixing mechanism (130) and a magnetic attraction mechanism (140), which are respectively used for performing uniform mixing processing and magnetic attraction processing on a biological sample. The portal frame (200) comprises a base (201) and a moving beam (202) capable of moving relative to the base (201). The sample processing apparatus (100) and the consumable assembly (300) are provided on the base (201). The pipetting apparatus (400) is provided on the moving beam (202) for implementing a pipetting operation between the consumable assembly (300) and the sample processing apparatus (100).

Abstract: A blending tube (10), comprising: a tube body (20), the tube body (20) being used for accommodating a sample; and a first stirring member (30) and a second stirring member (40), which are arranged on an inner wall (200) of the tube body (20), wherein a width-to-thickness ratio of the first stirring member (30) is greater than a width-to-thickness ratio of the second stirring member (40).
