     Further with reference to  FIG. 2 , the image collect module ( 20 ) collects a coordinate area image ( 30 ), including X-axis coordinate, Y-axis coordinate and Z-axis coordinate, from a controller ( 52 ) of a machine tool ( 10 ), as shown in  FIG. 3 . The coordinate area image ( 30 ) includes coordinate numeral patterns ( 31 ) that are provided from grating scales on the machine tool and shown on the controller ( 52 ). 
     The image receive module ( 21 ) includes an operational interface ( 211 ) disposed therein. The image receive module ( 21 ) receives the coordinate area image ( 30 ) and shows the coordinate area image ( 30 ) on the operational interface ( 211 ), as shown in  FIG. 5 . 
     The discern area set module ( 22 ) provides an operational tool, such as a mouse, for user to mark a specific area in the coordinate area image ( 30 ), which the user purpose to execute. 
     The discern and transform module ( 24 ) receives the datum in the marked specific area and transforms the coordinate numeral patterns ( 31 ) into digital coordinate numerals for system to compute, wherein the digital coordinate numerals are synchronously shown on a result display region ( 212 ) that is disposed in the operational interface ( 211 ). The ciphers, including 0 through 9, are previously installed and respectively correspond to pattern samples of the X-axis, the Y-axis and the Z-axis. 
     Hereinafter, a preferred embodiment in accordance with the present invention is provided for illustrative purpose. With reference to  FIG. 2 , a machine tool ( 10 ) includes a grating scale or an encoder disposed thereon for measuring the movements respectively on the X-axis, the Y-axis and the Z-axis. A workpiece ( 50 ) is secured on a horizontal platform ( 11 ) of the machine tool ( 10 ). A camera ( 51 ) is mounted on the machine tool ( 10 ) for collecting an image of the workpiece ( 50 ), wherein the image of the workpiece ( 50 ) is sent to a displayer ( 53 ) that is electrically coupled with the controller ( 52 ) of the machine tool ( 10 ). Consequently, the machine tool ( 10 ) can execute a measure process to the workpiece ( 50 ) via the controller ( 52 ) and the displayer ( 53 ). A coordinate display area ( 513 ) is disposed on the controller ( 52 ) for showing the coordinate values of the X-axis, the Y-axis and the Z-axis. 
     Accordingly, with reference to  FIGS. 3 through 8 , the system in accordance with the present invention executes the following processes. 
     Collecting and transforming the coordinate area image: the image collect module ( 20 ) collects an image from the coordinate display area ( 531 ) of the displayer ( 53 ) via a lens ( 201 ) that is disposed thereon, and forms an coordinate area image ( 30 ) including X-axis coordinate, Y-axis coordinate and Z-axis coordinate. The coordinate area image ( 30 ) including character patterns ( 31 ) including the X(axis), the Y(axis) and Z(axis), and coordinate numeral patterns ( 32 ). The coordinate area image ( 30 ) is transmitted to the image receive module ( 21 ). The image receive module ( 21 ) shows the coordinate area image ( 30 ) on the operational interface ( 211 ), as shown in  FIG. 5 . 
     Marking discern area: the discern area set module ( 22 ) provides an operational tool for user to mark an X-axis specific area, a Y-axis specific area and a Z-axis specific area which the user purpose to execute. In the preferred embodiment of the present invention, the operational tool is a phillips vernier ( 221 ) for user to sequentially mark the coordinate numeral patterns ( 32 ) of the X-axis, the Y-axis and the Z-axis and form multiple specific areas on the coordinate area image ( 30 ). Marking method: as shown in  FIG. 6 , the user can user the vernier ( 211 ) to click an upper limit point and a lower limit point of each of the coordinate numeral patterns ( 32 ). Continually, the user uses the vernier ( 211 ) to click a middle point of each of the coordinate numeral patterns ( 32 ) of one of the three axes to form a crossed discern area. The discern area set module ( 22 ) timely provides two-dimensional coordinates when the vernier ( 221 ) is moved. Accordingly, the user can gain an upper limit coordinate ( 61 ), a lower limit coordinate ( 62 ) and a central coordinate ( 63 ) that form a area waiting for discerning With reference to  FIG. 7 , a coordinate input interface ( 66 ) is electrically coupled with the discern and transform module ( 24 ) such that the user can respectively input the upper limit coordinate ( 61 ), the lower limit coordinate ( 62 ) and the central coordinate ( 63 ) into a corresponding input box via the coordinate input interface ( 66 ). As a result, the discern and transform module ( 24 ) can gain the information of each of the area that is waiting for discerning. As shown in  FIG. 7 , in the coordinate input interface ( 66 ), each axis has an upper limit coordinate input box ( 661 ), a lower limit coordinate input box ( 662 ) and a central coordinate input box ( 663 ) for user to respectively input the upper limit coordinate ( 61 ), the lower limit coordinate ( 62 ) and the central coordinate ( 63 ) of each of the coordinate numeral patterns ( 32 ). 
     Discerning and transforming: the discern and transform module ( 24 ) discerns the coordinate numeral pattern ( 32 ) in each area that is waiting for discerning and transforms the discerned coordinate numeral patterns ( 32 ) into a value datum that is provided to the system for computing. Accordingly, the computed value datum are shown on a result display region ( 212 ) of the operational interface ( 211 ) by ciphers, as shown in  FIG. 5 . 
     The process of marking discern area is executed when embedding the system of the present invention in the machine tool ( 10 ). Consequently, the process of discerning and transforming is timely executed after the image collect module ( 20 ) collects a coordinate area image ( 30 ) such that the coordinate numeral patterns ( 32 ) of the X-axis, the Y-axis and the Z-axis are transformed into coordinate values that can be computed by the system of the present invention and shown on the displayer ( 53 ) for a measure system to set a calculating parameter. 
     As described above, the system in accordance with the present invention collects a coordinate area image ( 30 ) including X-axis coordinate, Y-axis coordinate and Z-axis coordinate from a controller ( 53 ) of the machine tool ( 10 ) by image collect means. The coordinate numeral patterns ( 32 ) in the coordinate area image ( 30 ) are transformed into coordinate values that can be computed by the system of the present invention and timely shown on the displayer ( 53 ) by the skill of discerning and transforming. As a result, the system in accordance with the present invention executes the processes of discerning, transforming and showing at the same time for synchronously and effectively transforming coordinate datum. In addition, the transformed coordinate datum can be directly computing. The system in accordance with the present invention does not concern the collect skill of electric signal and optical signal of grating scale and encoder such that the system can be provided to any machine tool. As a result, the use scope of system in accordance with the present invention is widened.
