Embodiment
The present invention is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, dynamic of this present invention based on graphical analysis rolls thickness analysis and the automatic realization for jumping storehouse method
Flow is：
S100, set up elevation (thickness), image color thresholding mapping table, the present embodiment is using gray scale thresholding (points 255 etc.
Level) or 24 colored thresholdings, image series color thresholding is mapped as by unified spacing, such as：Represented per 1cm with 1 grade of gray value, one
2.55m height variation scope can be represented altogether, as shown in Figure 2.
S200, when rolling for the first time, height datum value is defined, by design data, measurement initial land form elevation and a reference value phase
After subtracting, thickness deviation is formed, plane coordinates distribution core is pressed to grid map after obtaining color value according to thickness color map
As in, a colour or gray scale picture, referred to as original elevation map are formed；
S300, collection in worksite rolled into track data, above-mentioned elevation color is consulted according to the elevation information of trajectory coordinates
Mapping table, with reference to trajectory plane coordinate and muller width information, the color information obtained using mapping table uses covering and drawing
(Cover) pattern, dynamic track drafting figure successively in chronological order, as shown in figure 3, another coloured picture or gray-scale map are formed,
Referred to as final (new) elevation map.
S400, in above-mentioned steps S300, by trajectory time inverted sequence draw, as shown in figure 3, obtaining a coloured picture or gray scale
Figure, is referred to as to roll elevation map for the first time.
S500, the picture that three are obtained to step S200, S300, S400, once obtain the color of corresponding points, and obtain color
Color offset, reversely consults mapping table, obtains the difference of 2 elevations.According to this difference, then draw and to form thickness analysis chart.
Elevation map and original elevation map comparative analysis are wherein finally rolled, draws out and rolls thickness analysis chart；It is first roll elevation map with
Original elevation map comparative analysis, draws out stone (first) and rolls thickness analysis chart；Analysis chart finally will be rolled with rolling for the first time
Elevation map is contrasted, and draws compacted depth distribution map by method consistent with the above, as shown in Figure 4.
S600, the layer thickness control parameter according to setting, with reference to the distribution map drawn, different thickness are counted based on pixel
Pixel quantity is distributed, grid point distribution, qualification rate etc. is closed.
S700, the compacted depth distribution map to dynamic formation, if there is well beyond the theoretical region for being compacted thickness, be
System is considered to have started a new base layer, realizes automatic jump storehouse, i.e., after corresponding time point, restart newly to roll base
The monitoring of layer and analysis work.
S800, it is completed roll new base layer roller compaction construction is organized on base layer again when, can be directly according to upper one
Individual base layer rolls performance data (final (new) elevation map), is used as original elevation map to carry out thickness analysis judgement.
