Problems solved by technology
They can only provide scene reproduction at the shooting point or with simple perspective interpolation on the baseline, and cannot perform scene rendering at any spatial point other than the baseline, and cannot reflect the scene information that the user cares about from any perspective required by the user, so it is extremely limited. degrees of freedom for scene observation
In addition, the panorama system used for landscape display is usually not measurable, that is, the absolute outer orientation information of image elements is not calibrated, so it is impossible to give a quantitative description of the spatial position of the scene content, which affects the accuracy of spatial information interpretation sex

Embodiment Construction
[0035] The present invention proposes a free and measurable panorama rendering method based on image model rendering, which extends and applies the image model-based rendering technology to large-scale scene free-viewpoint and measurable panorama reproduction, using only a small number of sampling points for ground panorama images Free viewpoint rendering with satisfactory measurement accuracy is obtained, which ensures the autonomy of observation viewpoint selection and the accuracy of obtaining spatial geometric information on demand. like figure 1 Shown is a work flow diagram of a freely measurable panoramic rendering method based on image model drawing in the present invention. The present invention is divided into five steps to complete, as follows:
[0036] Step (1): Collect ground panoramic image data.
[0037] The roadbed mobile measurement system is used to collect street view panoramas, which mainly reflect the side texture information of the ground landscape. The ...

The present invention is a free and measurable panorama reproduction method based on image model drawing. The method comprises the following steps: collecting and obtaining ground panorama image data, obtaining GIS image data obtained through satellite or aerial photography, and comparing GIS image data and ground panorama image data. Carry out registration to obtain the matching point lines and measurable information of the two, generate triangular grids of measurable information, and measurable panoramic reproduction of free viewpoints. This method builds a system, collects a small amount of ground panoramic image data, and communicates with satellite / Aerial photography GIS image data fusion, complete the scene description with measurable information triangular grid, and use the image model-based rendering technology to realize the panoramic reproduction of the free viewpoint in the whole space, which has both the autonomy of observation viewpoint selection and the measurement of spatial geometric information The authenticity of the system effectively guarantees the high degree of realism of any virtual viewpoint drawing. In a sense, it can be called a new combination of virtual reality and photogrammetry.
Description
[0001] Technical field [0002] The invention belongs to the technical field of remote sensing information systems, and relates to a free and measurable panorama reproduction method based on image model drawing. Background technique [0003] Large amount of information, high precision, and visualization are the current development directions of remote sensing information services. The goal is to provide users with experiential, communicative, differentiated, creative, and relevant services. Visibility is the basis of experience, on-demand measurement is the premise of creativity and differentiation, and spatiotemporal mineability provides technical support for relevant professional applications. It can measure panoramic images, which are both visible and measurable. As an important means of spatial information visualization, it can display scenes from all angles and provide measurement information, which conforms to the development trend of remote sensing information services....
