Embodiment
The present invention is further detailed explanation introduces below in conjunction with embodiment:
A kind of disposal route of metallic phase image information, this method realizes by metaloscope, the change-over circuit that is provided with a CCD imaging head in three heads of described metaloscope and optical information is converted to digital image information and output, the metaloscope base is provided with the output interface that is used to export described digital image information, one computing machine and display, described computing machine is connected with described output interface, disposal route specifically comprises the steps: 1), metallographic sample to be measured is placed on the objective table of metaloscope, utilize the CCD imaging head to gather comprehensively carrying out metallic phase image on to be measured; 2), image information is transferred to computing machine go forward side by side line identifier, storage; 3), regulate the distance between object lens and the metallographic sample to be measured, obtain the set of diagrams picture, the employing wavelet algorithm, above-mentioned figure is merged, obtain a picture rich in detail, the image after this fusion is carried out spatial alternation handle, can obtain the 3-D view of plane picture and recovery; 4), the 3-D view with above-mentioned plane picture and recovery stores specified folder into.
When described step 1) is carried out images acquired to metallic phase image, algorithm process is carried out in aspects such as the contrast in the image, brightness, be transferred to the focal length indicator, regulate the fine motion handwheel and the coarse motion handwheel of metaloscope, when focal length indicator numerical value reaches maximal value, can determine that focusing accurately.
Be specially: drawing, editor, measurement, mark, Flame Image Process, Boundary Recognition, report generation, be connected with AUTO CAD.Wherein, drawing comprises: straight line, parallel lines, vertical line, two-point drawing circle, make arc, draw polygon, draw rectangle, draw oval, fillet.When drawing, note the parameter of drawn object, we are except can be by dragging mouse draws when drawing, can also generate an accurate figure by input parameter, the pel that generates after drawing, acquiescence does not show mark, need can select the pel of mark, shows mark automatically by button or right-click menu.Can finely tune the position of mouse when drawing by keyboard; Editor comprises: duplicate, paste, shear, delete, extend, move, modification, rotation, UNDO, REDO, insertion literal, object is selected, the zone is selected, all selected, alignment etc.; Measure with mark and comprise: 2 distances, some linear distance, line linear distance, radius of circle, circular diameter, two wire clamp angles, radian, two circle eccentric angles, two circle distance of center circle etc., the precision of measurement is relevant with the microscope amplification multiple; Flame Image Process comprises: statistics with histogram, color adjustment, reduce color, gray-scale map, artwork master, 24 bitmaps, color compensating, edge sharpening, filtering, Z-Correct bump mapping Z-correct, lens, water wave, rotation, scaling and duplicate, paste, shearing, deletion, UNDO and REDO etc.; Image co-registration comprises: can import image from microscope or file or case library, system's image co-registration of same target is obtained a width of cloth distinct image, do measurement, mark, editor and image analysis processing and surface configuration reproduction etc. then.
Image co-registration is meant the certain Flame Image Process of image process about same target that the multi-source channel is collected, and extracts the information of each self-channel, and the same image of last comprehensive one-tenth is for observing or further the processing.The image interfusion method information of overall treatment multi-source passage as required efficiently, thus the utilization factor, system of image information automaticity improved effectively to target detection identification ground reliability and system.Its objective is the multiband information of single-sensor or information that the inhomogeneity sensor provided comprehensive in addition, eliminate the redundancy and the contradiction that may exist between the multi-sensor information, to strengthen transparency information in the image, improve precision, reliability and the utilization rate of decipher, to form clear, complete, information description accurately to target.
Owing to adopted image fusion technology, the layering distinct image is handled, make not too big requirement of smoothness, adopt image fusion technology and metallographic surface three dimension form reproducing technology to make the image that is obtained more can accurately represent the true condition of destination object so that measure and differentiate more accurately and reliably differentiating Object table.Even amplify simultaneously up to also target not being had too much requirement to the smoothness on surface under thousand times the state, so native system has wider application and scope.Image fusion technology can extract effective information to serial different piece distinct image and be fused into the three-dimensional picture rich in detail of a width of cloth, makes that the condition that is subjected to the object of observation is easier to differentiate.
Native system and method adopt wavelet algorithm, and aspect time complexity, done to optimize and improved, and the image texture features that adopts statistical analysis method to extract, the more problem that has solved the extraction of image three-dimensional spatial information.
Above-described only is preferred implementation of the present invention, should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, and these all belong to protection scope of the present invention.
