An embodiment of this application discloses a three-dimensional reconstruction method. The method in this embodiment of this application includes: obtaining an image of a first object and a camera pose of the image; determining a first normalized object location field NOLF image of the first object in the image by using a first deep learning network, where the first NOLF image indicates a normalized three-dimensional point cloud of the first object at a photographing angle of view of the image; determining, from a plurality of three-dimensional models in a model database based on the first NOLF image, a first model corresponding to the first object; determining a pose of the first object based on the first model and the camera pose of the image; and performing three-dimensional reconstruction on the first object in the image based on the first model and the pose of the first object.

According to one aspect of the present disclosure, a memory system is provided. The memory system may include at least one non-volatile memory device and a memory controller coupled to the at least one non-volatile memory device. A multi-level mapping table may be stored in the memory device. The multi-level mapping table may be configured to implement mapping from a logical address to a physical address. The memory controller may include a buffer. A portion of the multi-level mapping table may be stored in the buffer. The memory controller may be configured to perform a random read operation on the data stored in the memory device. In response to a random read range corresponding to the random read operation meeting a preset condition, the memory controller may be configured to adjust capacity for storing different levels of mapping tables in the buffer.

A high-efficiency pre-drilling pressure meter test apparatus for deep rock mass includes a rigid drill pipe, a probe, a pressurizing device and a signal processing device. The rigid drill pipe, comprising a top end and a tail end opposite to the top end, receives a fluid medium. The probe is connected with the tail end of the rigid drill pipe and communicates with the rigid drill pipe. The probe includes a measuring chamber. The fluid medium flows from the rigid drill pipe to the measuring chamber. The pressurizing device is connected to the top end of the rigid drill pipe and applies pressure to the fluid medium. The signal processing device is electrically connected with the probe to detect deformation of the measuring chamber with the change of the pressure and volume of the fluid medium in the pressurizing device.

Embodiments provide a character input method and an electronic device. The method includes acquiring a character input instruction, and displaying candidate characters generated by the character input instruction. The method also includes acquiring a first instruction input by a user, where the first instruction is used to select at least one target candidate character in the candidate characters. The method also includes acquiring a sliding gesture input by the user, and determining, according to the sliding gesture, a sliding track corresponding to the sliding gesture, where the sliding track is a track formed by action points of the sliding gesture on an output device. The method also includes acquiring, according to the sliding track, a position that is selected by the user for inputting a character, and inputting the at least one target candidate character to the position that is selected by the user for inputting a character.
