Subsequently, the measuring instrument 100 determines whether a capture button is input through a push on the center button c of the jog shuttle 276a by the user on the camera control unit 276 of the image capturing apparatus 270. (S5).

When the capture button is input as a result of the determination in step S5, the measuring apparatus 100 controls to output the enlarged image captured by the camera 275 of the imaging device 270 to the image output unit 130, and then enlarges the image. Image processing of the image recognizes a part number (PN) of the package P and a first pin that is an identifier (S6).

After the step S6, the instrument 100 performs the " output for identification number PN " and " output for first pin " and identification number PN and the first of the package P according to step S6. The "confirmation text" indicating the output of the 1 pin is output to the image output unit 130 (S7). Here, the "output for the identification number (PN)" and the "output for the first pin" may be output by marking the corresponding portions in fluorescent to red color, an example of the "confirmation text" is the identification number and the first This can be the phrase pin recognition complete.

After the step S7, the image pickup device 270 determines whether the user inputs the confirmation buttons ok and 276b or the cancel button x and 276c on the camera operator 276 (S8).

When the cancel button 276c input is completed according to the determination of step S8, the imaging apparatus 270 repeatedly performs steps S6 to S8 until the confirmation button 276b is input.

On the other hand, when the input of the confirmation button 276b is completed according to the determination of step S8, the imaging device 270 sends the identification number PN information to the measuring instrument 100, the position information of the first pin of the package P, Then, by transmitting the recognition command, based on the identification number (PN) information by the measuring instrument 100 based on the chip dimension data (Chip Dimension Data), the location information of the first pin (P6) extracted from the database 190 (S6) In the enlarged image in, the position of the first pin and the pin spacing between the remaining pins except the first pin are recognized (S10). Here, the measuring device 100 may output a completion message for pin spacing recognition to the image output unit 130 or / and the overlap output unit 121 to be recognized by the user.

Subsequently, the user performs the selection of the probing pins to be measured through the probe 200 on the package key P, and thus the probing pin location information, which is the location information on the pin to be probed by the probe rod 210, is selected. To transmit to the measuring instrument 100 (S11).

Accordingly, the measuring instrument 100 desires to be probed by the probe rod 210 through real-time image processing on the enlarged image using the corresponding probe pin position information and the position information of the first pin in step S10. The relative pin position on the package P with respect to the probing pin is recognized (S12).

After step S12, the instrument 100 extracts the pin number for the probe pin using the chip dimension data extracted from the database 190 as a relative pin position according to step S12. The function of the pin on the package P corresponding to the pin number is output to the overlap output unit 121 together with the image of the package P previously stored in the database 190 (S13).

After the step S13, the image capturing apparatus 270 determines whether the user pushes the capture button of the jog shuttle 276a on the camera control unit 276 for more than a predetermined time (step S13). S14).

When the input of the capture button for more than the preset time is completed according to the determination of step S14, when the image pickup device 270 transmits the first input completion signal to the measuring device 100, the output module of the measuring device 100. 182 outputs a package pin description (PIN DESCRIPTION) to the overlap output unit 121 as shown in FIG. 4 together with the package P image previously stored in the database 190 (S13).

On the other hand, when the input of the capture button for more than the predetermined time is not completed according to the determination of step S14, when the imaging device 270 transmits the first input failure signal to the measuring instrument 100, the measuring instrument 100 The overlap module 183 stores the enlarged image in step S6 as a background screen in the database 190 and then outputs the image to the image output unit 130 by applying a translucent effect on the enlarged image (S17). .

After the step S17, the overlap module 183 of the measuring device 100 enlarges the real-time photographed image captured by the camera 275 of the imaging device 270 in real time and the translucent effect in step S17. By overlapping the images, if the outlines of the overlapped screens match, the images are output to the image output unit 130. Along with the corresponding output, the user may perform the probing on the probing pin using the probe 200 to view the measurement signal output through the measurement signal output unit 120 of the measuring instrument 100 (S18).

As described above, the reason why the overlapped screen and the real-time shot image are output is for the purpose of probing the probe pin desired for subsequent probe while maintaining the sameness with respect to the enlarged image provided in step S6.

After the operation S18, the imaging apparatus 200 determines whether the user pushes the capture button of the jog shuttle 276a on the camera operator 276 for more than a preset time (S19). ). It is assumed that the preset time in step S19 is the same as the preset time in step S14.

When the input of the capture button over the preset time is completed according to the determination of step S19, the overlap module 183 of the measuring apparatus 100 releases the overlap of the real-time shot image and the enlarged image whose outline is matched. By doing so, the probing for the probing pin is completed (S20).
