Description
Technical field
The utility model relates to the cubing of large material stack body, especially a kind of windrow measuring system based on digital photograph three-dimensionalreconstruction stockpile model.
Background technology
Follow the level of the productive forces and requirements for automatic control to improve constantly, commercial production progresses into low margin age, in production, the control of consumptive material (being that material stockpile carries out volume, quality evaluation) is just become the key link of enterprise operation, yet starting material storage is huge, of a great variety, be all inevitable objective factor, the earthwork producing during such as capital construction, the stockpile of steel plant, the ore deposit heap of the raw coal accumulating heap in coal colliery, mining, port and pier etc.The windrow of these stockpiles and feeding major part are to be completed by bucket-wheel stacker reclaimer, aircraft-type stacker-reclaimer, planer-type stacker-reclaimer etc.Because bulk material deposition surface is irregular, stacked area is large, the difficulty of its volume of Measurement accuracy just apparent.Under this background, many similar Stocktaking modes have just been facilitated in the active demand that enterprise accurately measures for material stack volume.Wherein, the most traditional is hand gauging mensuration, in practice, find not only time-consuming, effort (need to by the artificial smooth one-tenth rule body of stockpile) of the method, and subjectivity is strong, is difficult to the storage condition of objective and accurate reflection material to reach the object of production control cost.Along with technical development, widespread use now be laser measuring technique.The method is science, accurately relatively, objectively progressive to some extent, but still be subject to measuring complex operation, expensive, precision does not reach many defects such as industrial requirements, be therefore difficult to popularize.
Utility model content
The purpose of this utility model is for above-mentioned existing problems, proposes a kind of windrow measuring system accurate, simple to operation, with low cost of measuring.
A kind of windrow measuring system based on digital photograph three-dimensionalreconstruction stockpile model of the utility model, comprise: aircraft, digital camera and processor, wherein, described aircraft is provided with GPS locating device, radar altimeter, electronic compass and digital camera, this system also comprises the controller of controlling aircraft and receiving the captured data of digital camera, the data input processor that controller is taken digital camera, described processor is by digital simulation go out the to be taken volume of windrow.
A kind of windrow measuring system based on digital photograph three-dimensionalreconstruction stockpile model of the utility model, wherein said aircraft is civilian aircraft.
A kind of windrow measuring system based on digital photograph three-dimensionalreconstruction stockpile model of the utility model, wherein said aircraft is the civilian aircraft of AR.Drone2.0 type.
A kind of windrow measuring system based on digital photograph three-dimensionalreconstruction stockpile model of the utility model, wherein said aircraft also comprises accelerometer and gyroscope.
A kind of windrow measuring system based on digital photograph three-dimensionalreconstruction stockpile model of the utility model, the data that wherein digital camera is taken are the view data that comprise three-dimensional coordinate.
The beneficial effects of the utility model are: measure accurate, simple to operation, with low cost, there is the advantages such as the general people, innovation, without special messenger's operation, field staff, according to operation instruction, just can use through on-the-spot practical operation several times, measuring system safety and environmental protection, noiselessness, radiation pollution, can arrive the daily position that cannot arrive of operator and measure, and without working as carrier by main equipment, measures, cheap, easily penetration and promotion.It will substitute the also progressively developing trend diversification of traditional measurement system, multifunction as new and high technology yield-power, thereby better for instructing production and operation, promote industry to become more meticulous to produce to provide the first-hand means of production reliably, so it has good market potential and immeasurable marketable value.
