Abstract
The invention discloses a kind of non-contact measurement cameras, including single anti-fuselage and camera lens, include that main reflective mirror, secondary reflective mirror, Fresnel focusing screen, collector lens, pentaprism, framing eyepiece, shutter, photosensitive-member and display screen, the photosensitive-member paste transparent film ruler on portrait attachment one side in the anti-fuselage of list.The beneficial effects of the invention are as follows:To the crack on measured object surface can shoot and measure the size in crack in real time, it is accurate that measurement facilitates when object distance is equal to lens focus twice.
Description
Technical field
The present invention relates to a kind of camera, especially a kind of non-contact measurement camera, for the crack to measured object surface
Etc. features accurately measured, belong to detection instrument technical field.
Background technology
In construction project detection, some building facilities and highway bridge, whether steel construction or concrete structure, all
Phenomena such as crack can occur during building use.In order to detect these cracks, conventional means is pacified on unmanned plane at present
Remote control shooting device is filled, tremendous contribution is made that for the promotion of work efficiency.But current detection is all simple shooting, not
The size for capableing of fracture does an accurate measurement.
Invention content
The goal of the invention of the present invention is:In view of the above problems, a kind of non-contact measurement camera is provided, it will be normal
Carry out appropriate reconstruction with slr camera, make its shooting while can also fracture accurately measured.
The first technical solution that the present invention uses:A kind of non-contact measurement camera, including single anti-fuselage and camera lens, institute
State in single anti-fuselage include main reflective mirror, secondary reflective mirror, Fresnel focusing screen, collector lens, pentaprism, framing eyepiece, shutter,
Photosensitive-member and display screen, the photosensitive-member paste transparent film ruler on portrait attachment one side.
Using the technical program, just film ruler is added in image when photosensitive-member is imaged.When using the present invention, need
Ensure that object distance is equal to twice of lens focus, is at this moment imaged the actual size size that size dimension is equal to testee, display screen
The image of upper presentation is exactly the photograph that overlaps of measured object and transparent film ruler, and measured object directly can be accurately read after enlarged drawing
Accurate scale of the body on transparent film ruler.
Second of technical solution that the present invention uses:A kind of non-contact measurement camera, including single anti-fuselage and camera lens, institute
State in single anti-fuselage include main reflective mirror, secondary reflective mirror, Fresnel focusing screen, collector lens, pentaprism, framing eyepiece, shutter,
Photosensitive-member and display screen are equal to twice of lens focus when institute on the display screen by being programmed in object distance on SDK platforms
The transparent film ruler of full size is shown on the original image of formation.When using the present invention, it is the same to keep up with a technical solution, needs
Ensure that object distance is equal to twice of lens focus, is at this moment imaged the actual size size that size dimension is equal to testee, passes through
Size of the film ruler presented on programming Control display screen on this image is also identical with actual size size, to realize quilt
The photograph that overlaps of object and transparent film ruler is surveyed, testee directly can be accurately read on transparent film ruler after enlarged drawing
Accurate scale.
Preferably, the transparent film ruler includes several circle concentric polygon graduated scales, larger polygon graduated scale
The smaller polygon graduated scale of number of edges is more, often encloses the minimum micron of each edge scale unit of the polygon graduated scale, most
Greatly millimeter.Further preferably, the three circle concentric polygon graduated scale of transparent film ruler setting, every edge lengths of inner ring are
Every edge lengths of 1mm, scale unit 0.1mm, centre circle are 2mm, and every edge lengths of scale unit 0.05mm, outer ring are 3mm,
Scale unit is 0.02mm.This preferably clear film ruler is suitble to the crack of all directions, need not rotate frequently in shooting process
Camera.
It is all made of tight shot in above two technical solution.
In conclusion by adopting the above-described technical solution, the beneficial effects of the invention are as follows:Camera lens can be equal in object distance
When focal length twice, to the crack on measured object surface shoot and measure the size in crack in real time, it is accurate that measurement facilitates.
