Detailed description of the invention

In order to clearly understand technical scheme, below in conjunction with accompanying drawing, the present invention is described in detail.Embodiments of the invention have exemplary effect, the improvement of the shape without essence that those skilled in the art make on embodiment of the present invention basis, all should belong to protection scope of the present invention.

The 3-D photography monitoring system of building deformation as shown in Figure 1, comprising:

Described photographic attachment parameter includes pixel size, film size height, film size width, focal length etc..Described photographic attachment can be digital camera, for gathering the image information of building.

Described image, it is common that a series of photos to building shooting, and adjacent photo generally has the degree of overlapping of 80 90%.Adjacent photo, is namely at the adjacent photo taking the photograph station shooting.

Described image control point coordinate in ground space coordinate system, is usually use total powerstation observation and obtains.Described total powerstation is 0.5 " level total powerstation.

The image space position at described image control point, is namely image control point image space coordinate on the image comprising this image control point.Generally, all there is the image space position of correspondence at image control point on every image comprising this image control point, this image space position when image capturing just it has been determined that.

Described monitoring point measurement module includes monitoring point input block, for the title of Input Monitor Connector point.The deformation of monitoring building, usually carry out the monitoring of many phases, when processing first-phase image, it is necessary to the title of monitoring point is input to correspondence position, in order to follow-up lookup and checking, and afterwards the second phase, the third phase ... when the X phase processes image, it is usually the title that need not re-enter monitoring point, certainly, according to specific needs, at different times, it is also possible to select to re-enter the title of monitoring point.

Described monitoring point, is provided on building, in order to reflect the characteristic point that building changes.The image space position of described monitoring point, is namely monitoring point image space coordinate on the image comprising this monitoring point.Generally, all there is the image space position of correspondence monitoring point on every image comprising this monitoring point, this image space position when image capturing just it has been determined that.

The three-dimensional distribution map of described monitoring point, is usually monitoring point three-dimensional coordinate scattergram in ground space coordinate system.According to this three-dimensional distribution map, it is possible to be visually observed that the distribution situation of monitoring point, to facilitate the follow-up analysis to monitoring point change.

The 3-D photography monitoring system of the building deformation of the present invention so that in the monitoring process to building deformation, the monitoring point quantity of setting and the situation of laying can according to monitoring it needs to be determined that, can until some cloud level, it does not have restrictive condition；The data of monitoring point of magnanimity can realize automatically extracting；The three-dimensional coordinate precision of monitoring point can reach ± 1 millimeter；The deformation behaviour of building can be monitored out rapidly, accurately, all sidedly；Workload is also much smaller than conventional point monitoring method；Common digital camera just can use, and expense is relatively low；Can be applicable to the monitoring to building deformation.

Usually, 3-D photography monitoring system also includes video conversion module, for converting the form of described image, in order to make the form of described image meet the requirements.Such as: generally during image collection, camera is set to RAW unprocessed form (original image coding data), obtaining image is CR2 form (RAW formatted file expands name), when later stage processes, it is generally required to import TIFF(TagImageFileFormat, it is abbreviated as TIFF, is TIF) image information, it is therefore desirable to CR2 is converted to tiff format.
