Image processor and environment information observing device

Abstract

The present invention provides an image processor and environment information observing device for processing information with high versatility according to a two-dimensional image. The image processor comprises a two-dimensional image information acquiring section for acquiring two-dimensional image information of a subject (2), a three-dimensional space information acquiring section for acquiring three-dimensional space information including the latitude, longitude, and altitude of the subject, an image displaying section (17) for displaying a two-dimensional image, an image information combining section (26) for combining the acquired two-dimensional image information and the three-dimensional space information, and an attribute information imparting section (27). The attribute information imparting section (27) imparts at least one of the items such as the latitude, longitude and altitude of the subject (2) included in the attribute information to each pixel of the two-dimensionalimage.

Description

technical field [0001] The invention relates to an image processing device and an environmental information observation device. Background technique [0002] Patent Document 1 discloses a device that measures a water level by installing a water measuring plate vertically with respect to the water surface and analyzing an image of a water level scale on which the relevant water measuring plate is read. [0003] Non-Patent Document 1 discloses a technique of orthographically transforming the coordinate system of a two-dimensional image into three-dimensional geographic coordinates, and then performing image analysis or geospatial analysis. [0004] Patent Document 2 discloses a technique for superimposing and displaying a three-dimensional image on a two-dimensional image.

AI Technical Summary

Problems solved by technology

[0007] However, in the conventional technology described in Patent Document 1, the water level is measured by disassembling the two-dimensional image in which the water level scale of the water measuring plate is read. However, it is difficult to read the scale when the illumination is insufficient, such as at night. , it is difficult to measure the correct water level, so it is hoped that the water level can be measured even without components such as water measuring boards that mark the elevation position

[0008] In the conventional technology described in Non-Patent Document 1, only two-dimensional position information can be referred to when image analysis is performed, and three-dimensional spatial information on the surface of the subject cannot be referred to.

In addition, after the orthographic projection transformation of the 2D image of the side of the subject acquired obliquely to the geographic coordinate system, the brightness information on the side of the subject may be lost

Therefore, there is a problem that the accuracy of image analysis deteriorates

[0009] On the other hand, in Patent Document 2, the three-dimensional shape data of the subject can be projected and drawn into a two-dimensional image, but the pixels within the range of the photographed subject on the two-dimensional image cannot be assigned or displayed. Longitude, latitude, elevation and other attribute information of the object, it is hoped that by obtaining the correct geographic coordinates of the object on the two-dimensional image, it is possible to perform highly versatile information processing
