Description
Technical field
The utility model belongs to displacement deformation observation field, more particularly to a kind of position based on CMOS photosensitive imaging sensors
Move deformation observing device.
Background technology
No matter deformation displacement in scientific and technical research or in terms of engineering construction suffers from its important function if measuring, such as
Measurement of Dam level and vertical displacement, tunnel perimeter deflection, construction level and vertical displacement etc..The method that deformation displacement measures
Useful laser distance meter, total powerstation, number (tradition) theodolite and Digital photographic are measured.
Existing deformation displacement measures the shortcomings of there are measuring device complexity and big errors, such as total powerstation, rangefinder
When being monitored for deformation displacement, the precision of equipment itself especially with the error in manual operation is in the process that can not keep away
Exempt from；It is limited that Digital photographic measures systematic error its use scope also existed in the unreliable and subsequent analysis of reference system.
Such as at present in constructing tunnel, tunnel perimeter deflection monitoring mostly uses greatly the convergence gauge of strip ruler and with extension ruler
Spirit level is completed, since steel ruler material is affected by temperature change, although using when temperature influenced etc. to be modified (mend
Repay), there are still relatively large deviation, this deviation is with environment difference, even greater than practical distortion displacement sometimes；Also, displacement monitoring
Data are to read to obtain by artificial observation, and in different time there are certain reading deviation, different people's same person exists
The same time, there is also read deviation；Further, since the presence of steel ruler, monitoring process are interfered with each other with constructing tunnel, work as measuring point
Between be that no thoroughfare for vehicles when hanging up steel ruler, when constructing tunnel has vehicle pass-through that can not also carry out deformation displacement data acquisition
's.It is similar when also there is a problem of using other methods such as total powerstation etc..
There is a kind of referred to as conventional digital camera photograph deformation observation method at present, however conventional digital camera becomes
The existing main problem of shape observation has the following aspects：
1, precision is not high, at present 2K images 1920*1080=2073600, about 2,000,000 points (pixel), 4K images

Point (pixel).When rate is 4000*3000=12000000 respectively, i.e. 12,000,000 points (pixel), level observation width is 10m
When (tunnel width), precision is poor, and the horizontal distance of point and point is about 10m/4000dpi=2.5mm.When rate is 7680* respectively
4320=33177600, about 33,000,000 points (pixel), when level observation width is 10m (tunnel width), precision is still not
The horizontal distance of ideal, point and point is about 10m/7680dpi=1.3mm.
2, data volume is big, and current most of finished product cameras are color camera, and the size of 8 2K color document images is about
For 1920*1080*8 ≈ 16.5MB, the sizes of 256 2K color document images is about 1920*1080*256 ≈ 532MB, 256
The size of 4K color document images is about 3840*2160*256 ≈ 2.120GB.
3, complicated for operation, the deformation observation of conventional camera first fetches scene photograph, carries out photo-number conversion,
Data volume is big, and referential is uncertain, in fact due to the data distortion in photo-digital conversion process, the higher data of resolution ratio
Amount is bigger, and compression reduces data volume but resolution ratio is low.
It is urgent need how so that displacement monitoring had both met the high requirement of rate respectively simultaneously or met suitable data volume requirement
It solves the problems, such as.
