For above-mentioned steps, be described in detail 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 schematic diagram, the base modules 14 that Fig. 5 is Fig. 4 and the schematic diagram of the positional information between scan module 12 of the scan module 12 scanning object 30 to be scanned of Fig. 1.First, in step 200, when user wants to scan an object 30 to be scanned, only need base modules 14 be arranged on the edge (as shown in Figure 3) of object 30 to be scanned and maintain static, so that base modules 14 can keep relative static with object 30 to be scanned, thereby reach the object that base modules 14 can be used as absolute position reference point.Next, in step 202, user can be arranged at scan module 12 another edge of object 30 to be scanned and towards the direction that approaches base modules 14, move and (for example toward one scan direction A as shown in Figure 4, move, but not limit by this, in other embodiments, scan module 12 can from the same edge of base modules 14, the opposite direction along scanning direction A moves towards another opposite edges) and start base modules 14 and scan module 12 simultaneously, now, the first reference cell 22 and second reference cell 24 of base modules 14 will send signal (as infrared ray, ultrasonic wave or electromagnetic wave signal etc.), after the signal that the first reference cell 22 that receives respectively base modules 14 at the first positioning unit 18 and second positioning unit 20 of scan module 12 and the second reference cell 24 send, path computing assembly 16 will receive and calculate respectively the distance of first positioning unit 18 distance the first reference cells 22 and the second reference cell 24 and the distance of second positioning unit 20 distance the first reference cells 22 and the second reference cell 24 from the time of the signal of the first reference cell 22 and the second reference cell 24 according to the first positioning unit 18 and the second positioning unit 20.Because the distance between the distance between the first positioning unit 18 and the second positioning unit 20 and the first reference cell 22 and the second reference cell 24 is fixing and known value, therefore, path computing assembly 16 can calculate respectively the accurate location in two-dimensional space of the first positioning unit 18 and the second positioning unit 20 according to calculating four distance values and two the known distance values that obtain, thereby draws the active path (step 204) of scan module 12 relative datum modules 14.
In more detail, take the computational process of Fig. 5 above-mentioned path computing assembly 16 as example illustrates.As shown in Figure 5, the first reference cell 22 sends respectively first signal S
1send respectively secondary signal S to the first positioning unit 18 and the second positioning unit 20, the second reference cells 24
2to the first positioning unit 18 and the second positioning unit 20.Due to base modules 14 with scan module 12 for start simultaneously, and the first reference cell 22 and the second reference cell 24 send signal after base modules 14 startups, therefore, at the first positioning unit 18, receives the first signal S that the first reference cell 22 sends
1and the second secondary signal S that sends of reference cell 24
2after, path computing assembly 16 just can receive first signal S according to the first positioning unit 18
1with secondary signal S
2time judge first signal S
1transfer to required time of the first positioning unit 18 and secondary signal S
2transferred to for the first required time of positioning unit 18, thereby calculate one between the first positioning unit 18 and the first reference cell 22 apart from d
1and first one between positioning unit 18 and the second reference cell 24 apart from d
3, whereby, path computing assembly 16 just can be determined the accurate location of the first positioning unit 18 in two-dimensional space.Similarly, at the second positioning unit 20, receive the first signal S that the first reference cell 22 sends
1and the second secondary signal S that sends of reference cell 24
2after, path computing assembly 16 just can receive first signal S according to the second positioning unit 20
1with secondary signal S
2time judge first signal S
1transfer to required time of the second positioning unit 20 and secondary signal S
2transferred to for the second required time of positioning unit 20, thereby calculate one between the second positioning unit 20 and the first reference cell 22 apart from d
2and second one between positioning unit 20 and the second reference cell 24 apart from d
4, whereby, path computing assembly 16 just can be determined the accurate location of the second positioning unit 20 in two-dimensional space.
When path computing assembly 16 determines that respectively after the first positioning unit 18 and the accurate location of the second positioning unit 20 in two-dimensional space, path computing assembly 16 just can detect the accurate location of scan module 12 in two-dimensional space.Then, at scan module 12, in relative datum module 14, toward scanning direction A, move to scan in the process of object 30 to be scanned, path computing assembly 16 just can be recorded the active path of scan module 12, 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, path computing assembly 16 just can combine the active path of the image of every a line of sweeping for object 30 to be scanned and scan module 12, and then be spliced into the complete image of corresponding object to be scanned 30, so can complete portable scanner 10 for the scan operation of object 30 to be scanned.
It is worth mentioning that; signal transmitting and receiving used in the present invention design can be not limited to the design that use reference cell that above-described embodiment mentions sends a signal to positioning unit; that is to say; so long as utilize signal transmitting and receiving between reference cell and positioning unit to detect the design of the position of positioning unit, all belong to protection scope of the present invention.For instance, the first positioning unit 18 and the second positioning unit 20 can change signal receiving/transmission device into, and the first reference cell 22 and the second reference cell 24 are signal reflex device.After starting scan module 12, the first positioning unit 18 can be used to the first reference cell 22 and the second reference cell 24 transmitted signals, also receive the signal reflecting respectively, the second positioning unit 20 can be used to the first reference cell 22 and the second reference cell 24 transmitted signals, also receive the signal reflecting respectively, whereby, path computing assembly 16 also can similarly detect the distance between the first positioning unit 18 and the second positioning unit 20 and the first reference cell 22 and the second reference cell 24 according to the time difference of the time difference of the first positioning unit 18 send and receive signals and the second positioning unit 20 send and receive signals, and then definite the first positioning unit 18 and the accurate location of the second positioning unit 20 in two-dimensional space, the reference frame of usining as the active path of subsequent calculations scan module 12.As for other related description and operating process, it can be analogized with reference to above-described embodiment, therefore repeat no more in this.
