Description
Technical field
The invention belongs to engineering geophysics prospecting, detection field, light-source system of the present invention is related to the refraction of light, scattering imaging
Principle, automation control, the control technique of light source, light source and photo matching principle technology, the uniform treatment technology of light.
Background technique
Cavern described herein include: water power prospecting in exploration adit, the diversion tunnel in power station, emptying tunnel, lead
It flows hole, working tunnel, the Hongdong etc. of overflowing, the diversion tunnel of hydropower complex, highway and railway tunnel etc. and carries out engineering investigation and detection
Tunnel be referred to as cavern.The preliminry basic research of conventional cavern is that cavern surface geological information is recorded by way of manually editing and recording；
The detection work of cavern mainly passes through detection mixed mud quality, thickness and hole top and backfills situation of coming to nothing, and detects action master
To include mixed mud crack (fracture length, width, development the parameters such as direction), mixed mud surface falls off, is height of coming to nothing, strong
Degree, thickness and enclose rock mass deformation etc..
With the development of computer and image processing techniques, surveyed using the photo of live shooting by modeling come the scene of completing
The three-dimensional space position and colouring information that can more intuitively show prospecting position attitude of rock, crack, off-load etc. are examined, the method can
To reach precise measurement and restore live real-texture information, this technology is known as outdoor scene modeling technique.
As the technical application that earth's surface outdoor scene models is extensive, such as the modeling of unmanned plane outdoor scene, the modeling of historical relic outdoor scene, side slope prospecting
Outdoor scene modeling etc., these work are all the outdoor scene modelings completed under natural light；The 3D photography carried out in film studio is also should
The continuation of class technology, it is essentially identical using the color and shape and truth of the threedimensional model of outdoor scene modeling technique foundation.Ground
Table outdoor scene dimensional Modeling Technology is using more and more extensive, can be into using the threedimensional model of the method foundation such as in side slope prospecting
Row Slope Stability Evaluation and side slope mapping operations；This technology can also be used in cavern and explored and detected work.Due to
In cavern without natural light, hole type is different, hole wall bumps are larger, hole diameter is not of uniform size, therefore, it is difficult to carry out outdoor scene modeling in cavern
Spend relatively high, hole domestic demand first solves the problems, such as light source, it is ensured that imaging precision and real colour, data acquisition have light source
Higher requirement.Following situations will affect the effect that outdoor scene models in cavern:
Gauge without light source in exploration adit or diversion tunnel room, first is that the light source color temperature manually added and natural light are inconsistent (artificial
Headlamp be all cool colour lamp, for colour temperature in 6500k or so, natural light colour temperature is 5500k or so, the photo shot under different-colour
The photo color shot under color and natural light has difference), second is that there are light-source brightness is uneven；
Cavern causes to excavate out-of-flatness because various factors influences, and hole deformationization is big, hole wall is concave-convex, will when photography is taken pictures
There are male and female faces for the photo for causing local hole section to shoot；
There are difference variation in cavern, light source is easy to burst in the biggish situation of the temperature difference.
Under the conditions of complicated cavern, threedimensional model is established by photogrammetric it may first have to solve the problems, such as light source.Have
Good light source, the image that can have just shot.Therefore, need to sufficiently design light source and camera and shoot hole wall positional relationship,
The brightness of light source and colour temperature, light source are the indoor service life in hole the problems such as.Currently, being built for being taken pictures in cavern using light source
The technology of vertical outdoor scene model is not mature enough, especially for the variation of hole type greatly, the exploration adit of hole wall chaotic source, to light source
Requirement it is higher.
