Description
Technical field
The utility model relates to a kind of investigation of urban built up volume ratio, particularly relates to a kind of image capturing system determining building floor area ratio, belongs to land management electronic informzation technique field.
Background technology
Building floor area ratio refers in certain plot, the ratio of gross building area and building area (domain areas).In recent years, when Old City Reconstruction planning or Land Appraisal, the data of the present floor area ratio based of specific region, city are all needed.Rationally and effectively control the use of urban land, plot ratio is vital.Therefore, finding a kind of quick, feasible Analytical system, is necessary to the building floor area ratio in investigation city.
The building floor area ratio method in investigation city has a lot of research both at home and abroad.Traditional method utilizes large scale topographical map directly to measure calculation, but the cycle is long, and cost is high.In urban construction, GPRS has the urban architecture plot ratio of actuality, estimate mainly through remote sensing survey method, domestic extraction and utilize the shadow information in remote sensing images to obtain the research of depth of building, general based on image technique, extract and utilize the shadow information of buildings, obtain depth of building or number of floor levels, and adopt the methods such as direct method, sciagraphy, shadowing method and high differentiation, estimation city plot ratio.
The disclosed building floor area ratio defining method based on Digital image technology of Chinese patent instructions CN101614807 (announcement on Dec 30th, 2009), the method is based on palm PC and digital camera, GPS and total powerstation are auxiliary, realize total digitalization collection and the record of field data information, and be combined with data processing system, carry out plot ratio calculating.But the method, is subject to the limitation of general digital camera shooting, and the impact of the factor such as manual operation instability, causes some Architectural drawing photographed fuzzyyer, or same building thing close shot, the distant view disunity of shooting; If these photos be transferred to data processing system process time, often can not get clear and complete buildings image, cause the calculating of plot ratio inaccurate.
In recent years, panoramic digital image technology was a kind of vision new technology developed rapidly, and this technology can build the three-dimensional panorama figure of shooting things.We consider this technology to be applied in buildings image acquisition, and design a set of acquisition system, for gathering building information more accurately, for subsequent calculations buildings plot ratio is offered help.
Utility model content
The utility model overcomes the deficiencies in the prior art, provides a kind of image capturing system determining building floor area ratio.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
Described system comprises rack body, support height regulating device, pan and tilt head, single anti-digital camera, flake, circular gathering line, several crucial collection points.
Described system belongs to field data acquisition system.
Described flake is arranged on single anti-digital camera.
The anti-digital camera of described list is arranged on pan and tilt head.
Described pan and tilt head is rack-mount.
Described circular gathering line, refers to buildings to be the center of circle, takes up an area and floor situation, determine reasonably to take radius, a border circular areas of laying according to buildings, as the scope gathering image,
Described crucial collection point, refers to the needs gathering image according to buildings, is laid in circular gathering line, several important collection positions.
Described support height regulating device, is arranged on crucial collection point;
The anti-digital camera of described list, the image that shooting buildings obtains, by data line, imports in the panorama mosaic software in data processing system.
Described panorama mosaic software, for the treatment of the image of single anti-digital camera shooting, obtains the panoramic picture of buildings.
Relative to prior art, the beneficial effects of the utility model are:
1, the utility model image capturing system, carries out shooting image to buildings, the picture material that gained is original, than the photo of the building photo later stage splicing gained of former single shot, more complete, more precisely, the error that the later stage calculates the buildings total area can be reduced.
2, digital single-lens reflex camera can exchange the camera lens of different size, and in pan-shot process, just needs to arrange in pairs or groups different fish eye lenses according to the camera of different model.
3, the effect that fish eye lens is maximum is that angular field of view is large, and this is conducive to shooting at close range Landscape Creation condition on a large scale; And fish eye lens has the quite long depth of field, be conducive to the long Deep Canvas showing photo.The panorama sketch fish eye lens of one 360 degree carrys out shooting and producing, only needs shooting several, adds the anti-digital camera of the list employing millions of pixel, image can be imported panorama split software easily, can generate the high-resolution panorama of 360 degree very easily.
4, in holder device, be fixed on by digital camera on the axis of rotation of pan and tilt head, so just can ensure that often opening image when rotating camera shooting is all a some photographs, the panorama sketch of split will be very perfect.
5, according to building actual conditions, take buildings as the center of circle, lay circular gathering line; In gathering line, lay several crucial collection points; Such design is more conducive to the stereo-picture of comprehensive, accurate shooting buildings.
The present invention can be applicable to following field or industry:
1, planning department is used for plot ratio measurement
2, house property department is used for plot ratio measurement
3, land departments is used for plot ratio measurement
