Be described in detail for above-mentioned steps below, please refer to Fig. 2, Fig. 3, Fig. 4, and Fig. 5, Fig. 3 is the schematic diagram that the base modules 14 of Fig. 1 is arranged at the edge of an object 30 to be scanned, Fig. 4 is the schematic diagram that the scan module 12 of Fig. 1 scans object 30 to be scanned, and Fig. 5 is the schematic diagram of the positional information between the base modules 14 of Fig. 4 and scan module 12.First, in step 200, when user wants scanning one object 30 to be scanned, only need base modules 14 to be arranged on the edge (as shown in Figure 3) of object 30 to be scanned and maintain static, to make base modules 14 and object 30 to be scanned that geo-stationary can be kept, thus reach the object that base modules 14 can be used as absolute position reference point.Next, in step 202., scan module 12 can be arranged at another edge of object 30 to be scanned and move towards the direction close to base modules 14 and (such as move toward one scan direction A as shown in Figure 4 by user, but do not limit by this, in other embodiments, scan module 12 can move towards another opposite edges along the opposite direction of scanning direction A from the same edge of base modules 14) and start base modules 14 and scan module 12 simultaneously, now, first reference cell 22 of base modules 14 and the second reference cell 24 will send signal (as infrared ray, ultrasonic wave or electromagnetic wave signal etc.), after the first positioning unit 18 of scan module 12 and the second positioning unit 20 receive the signal that the first reference cell 22 of base modules 14 and the second reference cell 24 send respectively, path computing assembly 16 will calculate the first positioning unit 18 apart from the distance of the first reference cell 22 and the second reference cell 24 and the second positioning unit 20 distance apart from the first reference cell 22 and the second reference cell 24 respectively according to the first positioning unit 18 and the second positioning unit 20 time received from the signal of the first reference cell 22 and the second reference cell 24.Due to the value that the distance between the first positioning unit 18 and the second positioning unit 20 and the distance between the first reference cell 22 and the second reference cell 24 are fixing and known, therefore, path computing assembly 16 according to the accurate location in two-dimensional space calculating four distance values obtaining and known two distance values and calculate respectively the first positioning unit 18 and the second positioning unit 20, thus can draw the active path (step 204) of scan module 12 relative datum module 14.
In more detail, the computational process of above-mentioned path computing assembly 16 is described for Fig. 5.As shown in Figure 5, the first reference cell 22 sends the first signal S respectively
1secondary signal S is sent respectively to the first positioning unit 18 and the second positioning unit 20, second reference cell 24
2to the first positioning unit 18 and the second positioning unit 20.Because base modules 14 and scan module 12 are for start simultaneously, and namely the first reference cell 22 and the second reference cell 24 send signal after base modules 14 starts, and therefore, receive at the first positioning unit 18 the first signal S that first reference cell 22 sends
1and the second secondary signal S that send of reference cell 24
2after, path computing assembly 16 just can receive the first signal S according to the first positioning unit 18
1with secondary signal S
2time judge the first signal S
1transfer to the time needed for the first positioning unit 18 and secondary signal S
2transfer to the time needed for the first positioning unit 18, thus calculate the distance d between the first positioning unit 18 and the first reference cell 22
1and the first distance d between positioning unit 18 and the second reference cell 24
3, whereby, path computing assembly 16 just can determine the accurate location of the first positioning unit 18 in two-dimensional space.Similarly, receive at the second positioning unit 20 the first signal S that first reference cell 22 sends
1and the second secondary signal S that send of reference cell 24
2after, path computing assembly 16 just can receive the first signal S according to the second positioning unit 20
1with secondary signal S
2time judge the first signal S
1transfer to the time needed for the second positioning unit 20 and secondary signal S
2transfer to the time needed for the second positioning unit 20, thus calculate the distance d between the second positioning unit 20 and the first reference cell 22
2and the second distance d between positioning unit 20 and the second reference cell 24
4, whereby, path computing assembly 16 just can determine the accurate location of the second positioning unit 20 in two-dimensional space.
After path computing assembly 16 determines the first positioning unit 18 and the accurate location of the second positioning unit 20 in two-dimensional space respectively, path computing assembly 16 just can detect the accurate location of scan module 12 in two-dimensional space.Then, move to scan in the process of object 30 to be scanned toward scanning direction A in relative datum module 14 at scan module 12, the active path of scan module 12 just can be recorded by path computing assembly 16, and the movement velocity of scan module 12 also can be calculated according to displacement and time relationship.Finally, as long as again according to the default resolution sizes of portable scanner 10 and in conjunction with the movement velocity of scan module 12 to determine the time interval of often sweeping a line, the image of every a line of sweeping for object 30 to be scanned just can combine with the active path of scan module 12 by path computing assembly 16, and then be spliced into the complete image of corresponding object to be scanned 30, so can complete the scan operation of portable scanner 10 for object 30 to be scanned.
