A method for laser distance measuring includes: emitting an incident ray α having an incident angle δ to a reflective surface of a laser reflecting mirror (), the incident ray α being reflected by the laser reflecting mirror () to generate a first reflected ray β, and the first reflected ray β irradiating an object to be measured (); capturing a second reflected ray θ and generating a laser image on a laser imaging plane (), the second reflected ray θ being generated by the reflective surface of the laser reflecting mirror () reflecting a return ray γ generated after the first reflected ray β irradiates a surface of the object to be measured; and determining, based on the laser image, a measurement distance A according to a geometrical trigonometry.

The present application discloses a data configuration query method and device. The method includes: determining at least two target data sets required to be queried by a query instruction and an ordered association between the target data sets, wherein the ordered association at least includes a unidirectional association and/or a bidirectional association; generating, on the basis of the at least two target data sets and the ordered association between the target data sets, a target association path; and outputting an OLAP model conforming to the target association path in a database. According to the present application, the technical problems of a large demand quantity of OLAP models included in an OLAP query system and a low utilization rate of the OLAP models in the related art can be solved.
