The close-range photography measurement device be suitable for close-range photography measurement tasks of the mountains and rivers.
Description
Technical field
The utility model relates to a kind of close-range photogrammetry device, relates in particular to a kind of close-range photogrammetry device that is suitable for mountain stream.
Background technology
In process that the river is conducted a research, in order quantitatively to portray river geomorphic evolution process under the different flow conditions, the researcher need measure the relief data in river.It is through digital terrain figure that tradition is obtained the river morphology data method, and this mode workload is big, and precision receives the topomap restriction.Then there is the expensive and slow shortcoming of sweep velocity of instrument in the laser scanning method, and can't measure bed configuration under water, measures the bigger limitation of existence so be applied in the landforms in river.
Close-shot photography measure technique has the precision height, and expense is low, and the high and portable advantage of efficient is extracted elevation information through close-shot photography measure technique at present and has been widely used in every field.Yet when using close-shot photography measure technique in the river, mountain area, owing to need range for measuring wide, riverbed undulating is big, and digital camera need be taking apart from the ground certain altitude in the air.Be not easy to stablize along with highly increasing camera in addition, make that like this difficulty increases and the precision reduction when mountain stream carries out close-range photogrammetry.
The utility model content
Using close-shot photography measure technique in the deficiency in river, mountain area for customer service is above-mentioned, the utility model provides a kind of close-range photogrammetry device that is used for mountain stream, makes and uses close-shot photography measure technique efficient and stable at mountain stream.
A kind of close-range photogrammetry device that is used for mountain stream; It comprises a helium balloon, a damper, a damping sensor, a laser range sensor, two digital cameras, an expansion link and an integrating apparatus; Said digital camera and laser range sensor are fixed in expansion link, and expansion link links to each other with helium balloon through damper, and said damper is used for stablizing expansion link; Said damping sensor is used to measure the swing of expansion link; Said laser range sensor is used for measuring apart from floor level, and said helium balloon is used to make package unit to be suspended in the air, and said integrating apparatus comprises a wireless receiver and a controller; Be used to receive terrestrial wireless signal, laser ranging data, damping sensor signal, and the control digital camera is taken pictures.
The beneficial effect of the utility model is: said helium balloon is suspended in aerial certain altitude with package unit; Make measurement range control easily; Said damper can reduce the swing of expansion link; Can make digital camera and laser range sensor keep vertical direction, make and take pictures more stablely, improve efficiency of measurement and quality.
Description of drawings
Fig. 1 is a kind of structural representation that is used for the close-range photogrammetry device preferred embodiments of mountain stream of the utility model.
Fig. 2 is the synoptic diagram that is connected of integrating apparatus and digital camera, damping sensor and laser range sensor among Fig. 1.
Embodiment
Combine Figure of description at present, the utility model further described:
Please refer to Fig. 1; The utility model is a kind of close-range photogrammetry device that is used for mountain stream, and helium balloon 1 is used to make package unit to be suspended in the air, and digital camera 7 and laser range sensor 5 are fixed in expansion link 6; Expansion link 6 links to each other with helium balloon 1 through damper 4; Damper 4 is used for stablizing expansion link 6, and damping sensor 3 is used to measure the swing of expansion link 6, and laser range sensor 5 is used for measuring apart from floor level.
Please refer to Fig. 2, integrating apparatus 2 comprises a wireless receiver 8 and a controller 9, is used to receive terrestrial wireless signal, laser ranging data, damping sensor signal, and control digital camera 7 is taken pictures.
When a kind of close-range photogrammetry device that is used for mountain stream uses; Its measuring process is specially: through said integrating apparatus 2 altitude range that need take pictures is set; Highly regulate expansion link 6 to respective length according to being provided with, measuring-signal is prepared in the emission of terrestrial wireless transmitter.With helium balloon 1 inflation, control helium balloon 1 slowly raises, and laser range sensor 5 is duplicate measurements and floor level in uphill process, when reaching the setting height scope, triggers and highly accomplishes signal.Damper 4 continues to reduce the swing of expansion link 6 in uphill process, the swing of damping sensor 3 test constantly expansion links 6 triggers the orientation and accomplishes signal when expansion link 6 is static, and two digital cameras 7 of controller 2 controls this moment are taken pictures.Taking pictures to accomplish moves to next place to be measured with helium balloon 1, repeats said process, accomplishes the mountain stream close-range photogrammetry.
The above is merely the preferable possible embodiments of the utility model; Said embodiment is not the scope of patent protection in order to restriction the utility model; Therefore instructions of every utilization the utility model and equivalent structure that the accompanying drawing content is done change, and in like manner all should be included in the protection domain of the utility model.
