The invention provides a method for optimizing a design of a vertical seismic profile observation system for seismic exploration, which comprises the following steps: establishing a seismic geological model by known data; distributing more than two different observation systems; forwarding a response of a seismic wave field; calculating a position of a reflective spot, incident and reflection angles and length or ray impact frequency, and counting characteristic parameters again to construct an analysis map; and determining the optimal scheme for actual exploration according to a geological target. The method adopts multi-parameter analysis based on a spacial model, has strong rationality of results, adapts to details, can improve data acquisition quality, is suitable for homogeneous spaces and one-dimensional, two-dimensional or three-dimensional models, can be used for non-zero spacing, Walkaway and 3D-3C VSP exploration designs, and also can be used for analyzing VSP exploration designs of longitudinal waves, transverse waves and converted waves.

The invention relates to the field of hybrid reality technology, in particular to a method and system for obtaining a hybrid reality scene. The method of the invention is characterized by generating afirst virtual scene through a first hybrid reality headset display, and acquiring a real scene by a solid camera, wherein the solid camera is physically fixed with a second hybrid reality head-mounted display; mapping a first spatial model corresponding to the first hybrid reality headset display and a second spatial model corresponding to the second hybrid reality headset display to the same coordinate system; and superimposing the first virtual scene and the real scene according to the coordinate system to obtain a mixed real scene. The hybrid reality scene viewed by a user wearing a hybridreality head-mounted display is presented from a third person perspective.

The invention provides a Bayesian model-based dynamic flight time measurement method. The method comprises the following steps of S1, selecting a pulse ToF camera; S2, building a Bayesian flight timemodel; S3, building a multipath model; S4, building a state spatial model; and S5, building a steady temporal model. A generative model is built by using motions of the camera and an object as observation values; principle-based Bayesian inference is performed on the model; by shooting multiple frames of infrared images, depth estimation is obtained; a positive measurement mode is designed; supplementary information is collected as time goes on; and by a using a regression tree method, first real-time time integration is demonstrated in low operation and low memory operation. Through the Bayesian model-based dynamic flight time measurement method provided by the invention, the camera is improved in calculation efficiency and information capture; the depth precision is improved in a strongbaseline method; the timeliness and the transformation resistance are achieved; and the system precision is improved.
