Description
Technical field
The utility model belongs to the three-dimensional detection technique of mineral compound field, is specifically related to a kind of production scene three-dimensional real-time data acquisition system that detects that gathers materials.
Background technology
The pavement structure that bituminous pavement is made up of the surface layer of building as binder bonding mineral aggregate with asphalt material and all kinds of basic unit and bed course, bituminous pavement is operated under complicated load stress and the environmental baseline, in order to ensure its pavement performance, need implement strict quality to material selection, production and the forming process of asphalt.
The mineral aggregate of asphalt pavement mixture is formed the grating that is called asphalt.Asphalt mainly refer to without pave, bituminous concrete mixture and the bituminous concrete moxture of compacting.The mineral aggregate of the grating up to specification that bituminous concrete mixture is made up of coarse aggregate, fine aggregate and the filler of proper proportion and pitch mix and the asphalt that meets technical standard made.The gradation composition of asphalt has determined the pavement performance of bituminous pavement.Because the decisive role of asphalt mixture gradation, the test test item of the work progress routine of bituminous pavement is exactly the grating of asphalt, with the control construction quality.The grating of existing asphalt detects mensuration that content mainly comprises bitumen content, separation that each grade gathers materials and the mensuration of quality.The separation that each grade gathers materials in the asphalt and the classic method of mensuration mainly are to record behind the reciprocating gird that gathers materials after with ro-tap testing sieve shaker pitch being extracted.Mineral aggregate in the asphalt is formed the quality check project important when being asphalt pavement construction of testing, and whether it is used for the size analysis of the recovery mineral aggregate behind the asphalt extractable bitumen content, adhere to specification to check its composition.Abroad during the mineral aggregate gradation when the evaluation asphalt pavement construction, generally in quality requirements, do not stipulate whole sieve apertures are sieved, check, and pay attention to the quality inspection of crucial sieve aperture, to reduce workload.
There is complicated operation in said method, obtain the defective that the not high and test figure of data precision mainly depends on operator's test level; Used test detecting equipment is bulky mostly, and is expensive, and the test period is longer.For some parameter of the mineral aggregate aggregate particle of asphalt, as corner angle and faller gill shape particle, only rely on screening to determine, also need extra test.In addition, when measuring bitumen content employing extracting, owing to be to use organism, easily human body is produced injury, adopt the rule of burning to pollute the environment.
Therefore, need seek a kind of device and method of detection asphalt mineral aggregate gradation that can quick nondestructive, image processing techniques can be realized this goal substantially, but by the 2-D data that image process method can only obtain gathering materials, it is many times still not ideal enough to be used in the analysis of gradation composition degree of accuracy; The inventor is at the problems referred to above, designed and be used for digitalized image acquisition system that aggregate grading detects and acquisition method (number being the Chinese invention patent of CN101920043B referring to Granted publication), its structure as shown in Figure 1, this need realize sampling collection to the stream that gathers materials by movable cutting plate is set, solve the image collecting device that in the past gathers materials and to have carried out the problem that all images is gathered to the whereabouts stream that gathers materials, overcome the poor image quality that collects, particle is difficult to be separated, the defective that the deal with data amount is big, but use through scene after a while, the inventor finds the problem that it still exists some can not be ignored:
Problem 1: because existing cutting plate tilts, though realized the shunting of gathering materials, caused the speed that falls of gathering materials to can not get Optimal Control, and on cutting plate each section falling speed inequality of gathering materials, the data distortion that causes camera to be gathered causes than mistake even mistake result;
Problem 2: when taking directly gathering materials on cutting plate or the travelling belt, because cutting plate or travelling belt surfacing are smooth, if laying gathering materials on it does not all hide the surface, LASER Light Source beat have inevitably in the above reflective, can there be much not tractable noise spots in the data of Cai Jiing like this, data then can not be used when serious, have used this data if in time do not find in the acquisition process process, and then the result error can be very big.Therefore need tight tracking be arranged to gatherer process, give up some abnormal datas in case of necessity, but cause test efficiency lower like this, waste time and energy, and measuring accuracy can not be guaranteed.
Problem 3: camera is taken best visual field, position and the angle of inclination of adjusting cutting plate apart from control lever and angle control lever have respectively been designed in the existing system, effectively shunting has realized gathering materials, but in the time of adjustable range control lever and angle control lever, the relative position with camera of gathering materials on the cutting plate changes and causes camera to work under best visual field all the time, can produce the influence that can't quantize to the result.
Problem 4: existing system and method, utilize line-scan digital camera to collect two dimensional image, and become volume by the data-switching of calculating the two dimension of to gather materials, and then obtain asphalt mixture gradation, because the complicacy that image is handled, the grating of obtaining and actual stage are furnished with bigger deviation.
