A LiDAR device (14) for scanning measurement of a distance to an object (12) comprises a photonic integrated circuit (52) with a plurality of optical waveguides (38) and a plurality of couplers 40). Each coupler (40) emits light guided in the optical waveguide (38) into free space and / or couples light propagating in free space into the optical waveguide (38). A collimating optical system (44) collimates light beams emitted by the couplers (40) and / or focuses collimated light beams. Microlenses (54; 54a, 54b) form real or virtual images of associated couplers (40), said images being arranged in an object field (56) of the collimating optical system (44). The collimating optical system (44) has a collimator numerical aperture which is greater than each of the coupler numerical apertures. Each microlens (54; 54a, 54b) has a collimator-side numerical aperture that is greater than its coupler-side numerical aperture. In this manner, insertion losses caused by NA mismatch are reduced.

This invention discloses a data cleaning method, apparatus, electronic device, and storage medium, relating to the field of data processing technology or other related fields. The method includes: receiving a data cleaning request submitted by a user and parsing the request to obtain N cleaning tasks, each corresponding to a preset cleaning rule. Each cleaning task includes at least a task object field, task execution conditions, and task execution order, where N is a positive integer. For each cleaning task, a filter template is matched according to the preset cleaning rule, and filter entity code is generated by combining the filter template, task object field, and task execution conditions. According to the task execution order, the N filter entity codes are organized into a chained execution structure to generate chained execution code. The chained execution code is injected into an execution engine, and the execution engine is run to obtain the data cleaning result. This invention solves the technical problem of low efficiency in traditional data cleaning methods in related technologies.

A data augmentation method includes: obtaining first field images captured in a first field and second field images captured in a second field; cropping first object images and second object images respectively from the first field images and the second field images; training an object generation model by the first object images and the second object images; generating new object images by the object generation model; synthesizing the new object images into the second field images as new object field images; and training an object discrimination model with the second field images and the new object field images.

This invention belongs to the field of data processing technology, specifically relating to a Java runtime dynamic data mapping method, system, and computer device based on Web configuration and bytecode enhancement. The method includes the following steps: S1, receiving user-defined mapping rules between source and target POJO objects via a Web interface; S2, in the Java Virtual Machine runtime environment, when the classes of the source and target POJO objects are loaded, enhancing the bytecode of the classes by statically injecting a metadata cache structure into the bytecode. The metadata cache structure includes field type information and corresponding field access method handles; S3, resolving the source and target field paths according to the mapping rules to form an access chain, and based on the field access method handles, retrieving values ​​from the source POJO object field by field along the access chain and assigning them to the target POJO object to complete the data mapping. This method supports dynamic configuration on the Web client and achieves near-handwritten code performance at the Java runtime.
