[0051] Figure 1 A flow chart of a dimension measurement method provided by an embodiment of the present invention is applicable to the situation where the relatively accurate dimension of the component to be measured needs to be automatically determined. The method can be executed by a dimension measurement device, such as Figure 1 As shown, the specific steps include:

[0052] Step 110: Acquire a component image of the component to be tested, and determine a component identification of the component to be tested and an offset of the component image according to a standard component image corresponding to the component image.

[0053] Figure 2 A schematic diagram of the structure of a dimension measurement system provided by an embodiment of the present invention is shown in FIG. Figure 2 As shown, the dimension measuring system includes a slide (loading slide), a turntable (visual camera turntable), an image acquisition device (visual industrial camera) and a three-dimensional coordinate measuring machine, wherein the slide is used to move the component to be measured into or out of the storage table of the three-dimensional coordinate measuring machine, the turntable includes a support rod and a rotating rod, one end of the rotating rod is connected to the image acquisition device, the rotating rod is used to move the image acquisition device into or out of the top of the storage table, the image acquisition device is used to acquire the component image of the component to be measured placed on the storage table, and the three-dimensional coordinate measuring machine is used to measure the dimension of the component to be measured placed on the storage table.

[0054] Specifically, after the slide table is controlled to slide out of the storage table of the three-dimensional coordinate measuring machine, the operator can place the component to be measured on the slide table, and then the slide table is controlled to slide into the storage table of the three-dimensional coordinate measuring machine to move the component to be measured into the storage table of the three-dimensional coordinate measuring machine. The rotating rod of the control turntable is rotated to move the image acquisition device above the storage table, and the image acquisition device is controlled to acquire the component image of the component to be measured placed on the storage table.

[0055] Furthermore, the component identification of the component to be tested can be determined based on the standard component image corresponding to the component image. On the one hand, the standard component image corresponding to the component image can be searched in the standard component image library, and the component identification of the standard component image corresponding to the component image can be determined as the component identification of the component to be tested. On the other hand, the received component identification can be determined by determining the standard component image corresponding to the component image among the standard component images corresponding to each component identification. When it is determined that the component image matches the standard component image corresponding to the component image, the received component identification is determined as the component identification of the component to be tested.

[0056] When acquiring the component image, the center coordinates of the component image may also be acquired. The offset of the component image may be determined according to the center coordinates of the component image and the center coordinates of the standard component image corresponding to the component image.

[0057] In the embodiment of the present invention, after the image acquisition device acquires the component image of the component to be measured, the component identification of the component to be measured and the offset of the component image are determined according to the standard component image corresponding to the component image.

[0058] Step 120: determine a standard measurement trajectory corresponding to the component identification, and determine a current measurement trajectory according to the standard measurement trajectory and the offset.

[0059] Specifically, when the three-dimensional coordinate measuring machine measures the dimensions of a component, it is necessary to adjust the standard measurement track of the component according to the position of the component on the storage table to determine the current measurement track. Therefore, it is necessary to first determine the standard measurement track corresponding to the component identification. Since the standard measurement track is determined according to the position of the component to be measured on the storage table of the three-dimensional coordinate measuring machine when the standard component image of the component to be measured is obtained, the standard measurement track can be adjusted based on the offset between the component image and the standard component image corresponding to the component image to obtain the current measurement track.

[0060] In the embodiment of the present invention, the standard measurement track corresponding to the component identification of the component to be measured is adjusted according to the offset between the component image of the component to be measured and the standard component image corresponding to the component image, so as to obtain the current measurement track for measuring the size of the component to be measured.

[0061] Step 130: Control a three-dimensional coordinate measuring machine to measure the component to be measured based on the current measurement trajectory to determine the component size of the component to be measured.

[0062] Specifically, after determining the current measurement trajectory, the current measurement trajectory can be sent to a three-dimensional coordinate measuring machine, so that the three-dimensional coordinate measuring machine can control the movement of the measuring arm based on the current measurement trajectory to measure the size of the component to be measured and obtain the component size of the component to be measured.

[0063] In the embodiment of the present invention, the measurement arm of the three-dimensional coordinate measuring machine is controlled to move based on the current measurement trajectory to achieve the dimension measurement of the component to be measured and obtain the component dimension of the component to be measured.

[0064] The dimension measurement method provided by an embodiment of the present invention includes: acquiring a component image of a component to be measured, determining a component identification of the component to be measured and an offset of the component image according to a standard component image corresponding to the component image; determining a standard measurement trajectory corresponding to the component identification, and determining a current measurement trajectory according to the standard measurement trajectory and the offset; and controlling a three-dimensional coordinate measuring machine to measure the component to be measured based on the current measurement trajectory to determine the component size of the component to be measured. The above technical scheme can firstly acquire a component image of the component to be measured based on an image acquisition device, and secondly determine a standard component image corresponding to the component image, and determine a component identification of the component to be measured according to the standard component image corresponding to the component image, and determine an offset of the component image according to the component image and the standard component image corresponding to the component image, and thirdly determine a standard measurement trajectory corresponding to the component identification, and adjust the standard measurement trajectory according to the offset of the component image of the component to be measured and the standard component image corresponding to the component image, so as to obtain a current measurement trajectory for dimensional measurement of the component to be measured, and then control a three-dimensional coordinate measuring machine to measure the component to be measured based on the current measurement trajectory. Specifically, the measurement arm of the three-dimensional coordinate measuring machine can be controlled to move based on the current measurement trajectory to achieve dimensional measurement of the component to be measured, obtain the component size of the component to be measured, and further automatically determine a more accurate component size of the component to be measured.

[0065] Figure 3 This is a flow chart of another dimension measurement method provided by an embodiment of the present invention. This embodiment is specific based on the above embodiment. Figure 3 As shown, in this embodiment, the method may further include:

[0066] Step 310: Determine the standard component image corresponding to each component identification according to the received component identification and the acquired standard component image.

[0067] Specifically, the operator can input the component identification of the component based on the terminal device and place the component on the slide table that slides out of the three-dimensional coordinate measuring machine. The terminal device can send the component identification to the computer device, and the computer device can also control the slide table to slide into the three-dimensional coordinate measuring machine. When it is determined that the slide table slides into the three-dimensional coordinate measuring machine, the computer device can control the rotation rod of the turntable to rotate to move the image acquisition device to the top of the storage table, and then control the image acquisition device to acquire the component image of the component placed on the storage table. At this time, the acquired component image is the standard component image.

[0068] In practical applications, the component identification may be received multiple times and the standard component image of the component corresponding to the component identification may be obtained. Of course, the component identification and the standard component image corresponding to the component identification may also be stored accordingly.

[0069] In addition, when acquiring the standard component image, the center coordinates of the standard component image can also be acquired.

[0070] In the embodiment of the present invention, after receiving the component identification and acquiring the standard component image of the component corresponding to the component identification, the component identification and the standard component image corresponding to the component identification are stored correspondingly, thereby realizing the corresponding storage of the component identification and the standard component image.

[0071] Step 320: Acquire a component image of the component to be tested.

[0072] Step 330: Determine the standard component image corresponding to the component image from the standard component images corresponding to the component identifications according to the component image, or determine the standard component image corresponding to the component image from the standard component images corresponding to the component identifications according to the received component identification to be tested.

[0073] Specifically, the component image and the standard component images corresponding to the component identifications can be compared, and the standard component image with the highest similarity to the component image can be determined as the standard component image corresponding to the component image; or, the received component identification to be tested can be determined to determine the standard component image corresponding to the component identification to be tested in the corresponding stored component identification and the standard component image corresponding to the component identification, and the standard component image corresponding to the component identification to be tested can be determined as the standard component image corresponding to the component image.

[0074] In the embodiment of the present invention, it is achieved to determine the standard component image corresponding to the component image.

[0075] Step 340: Determine a component identification of the component to be tested and an offset of the component image according to a standard component image corresponding to the component image.

[0076] In one implementation, step 340 may specifically include:

[0077] The component identification corresponding to the standard component image corresponding to the component image is determined as the component identification of the component to be measured; and the offset of the component image is determined according to the first center coordinate of the component image and the second center coordinate of the standard component image corresponding to the component image.

[0078] The offset includes a horizontal axis offset and a vertical axis offset.

[0079] Specifically, the component identification corresponding to the standard component image corresponding to the component image can be determined as the component identification of the component to be tested, thereby determining the component identification. The coordinate offset value of the first center coordinate of the component image and the second center coordinate of the standard component image corresponding to the component image is determined, and the coordinate offset value is determined as the offset of the component image relative to the standard component image corresponding to the component image.

[0080] In the embodiment of the present invention, the component identification of the component to be tested and the offset of the component image are determined according to the standard component image corresponding to the component image.

[0081] Step 350: determine a standard measurement trajectory corresponding to the component identification, and determine a current measurement trajectory according to the standard measurement trajectory and the offset.

[0082] Specifically, after determining the standard component image corresponding to the component identification, the standard measurement trajectory corresponding to the component identification can be determined according to the theoretical measurement trajectory corresponding to the component identification and the center coordinates of the standard component image. Specifically, the theoretical measurement trajectory corresponding to the component identification can be adjusted based on the center coordinates of the standard component image corresponding to the component identification to obtain the standard measurement trajectory corresponding to the component identification. Furthermore, the standard measurement trajectory can be adjusted based on the offset of the component image of the component to be measured and the standard component image corresponding to the component image of the component to be measured to obtain the current measurement trajectory of the component to be measured.

[0083] In the embodiment of the present invention, the standard measurement trajectory of the component to be measured is adjusted according to the component image of the component to be measured and the offset of the standard component image corresponding to the component image of the component to be measured, so as to obtain the current measurement trajectory for measuring the size of the component to be measured.

[0084] Step 360: Control the three-dimensional coordinate measuring machine to measure the component to be measured based on the current measurement trajectory to determine the component size of the component to be measured.

[0085] Specifically, after determining the current measurement trajectory of the component to be measured, the current measurement trajectory of the component to be measured can be sent to a three-dimensional coordinate measuring machine, so that the three-dimensional coordinate measuring machine can control the movement of the measuring arm based on the current measurement trajectory to measure the size of the component to be measured and obtain the component size of the component to be measured.

[0086] In practical applications, the coordinate measuring machine needs to be reset to zero each time it is restarted and the storage table is determined to be empty.

[0087] In addition, the component size of the component to be measured can be saved, and after saving the component size of the component to be measured, the component size of the component to be measured can also be deleted. The change of the component size of the component to be measured can also be counted on a monthly or annual basis.

[0088] In the embodiment of the present invention, the measurement arm of the three-dimensional coordinate measuring machine is controlled to move based on the current measurement trajectory to achieve the dimension measurement of the component to be measured and obtain the component dimension of the component to be measured.

[0089] Step 370: Determine the standard size of the component to be tested according to the component identification.

[0090] Specifically, if the computer device pre-stores the standard size of the component corresponding to each component identification, the standard size of the component to be tested can be determined according to the component identification of the component to be tested. If the computer device does not pre-store the standard size of the component corresponding to each component identification, the component identification can be sent to the server, and the server determines the standard size of the component to be tested according to the component identification of the component to be tested.

[0091] It should be noted that after the component identification of the component to be tested is determined, the standard size of the component to be tested can be determined according to the component identification of the component to be tested, that is, step 370 can be performed after step 340 and before step 380 .

[0092] In the embodiment of the present invention, the standard size of the component to be tested is determined according to the component identification of the component to be tested.

[0093] Step 380: Determine a dimensional error between the component size and the standard size, and when it is determined that the dimensional error is within a preset error range, determine that the component to be tested is qualified.

[0094] Specifically, the component size of the component to be tested may include the size of each area of ​​the component to be tested. After determining the component size and the standard size of the component to be tested, the size error of each area may be determined, and then the size error of the component size and the standard size may be determined based on the size error of each area. If the size error is within the preset error range, the component to be tested is determined to be qualified, otherwise, the component to be tested is determined to be unqualified.

[0095] In the embodiment of the present invention, the conformity inspection of the component to be tested is implemented according to the dimensional error between the component size and the standard size.

[0096] The dimension measurement method provided by an embodiment of the present invention includes: determining the standard component image corresponding to each component identification according to a received component identification and an acquired standard component image; acquiring a component image of the component to be measured; determining the standard component image corresponding to the component image in the standard component image corresponding to each component identification according to the component image, or determining the standard component image corresponding to the component image in the standard component image corresponding to each component identification according to the received component identification; determining the component identification of the component to be measured and the offset of the component image according to the standard component image corresponding to the component image; determining a standard measurement trajectory corresponding to the component identification, and determining a current measurement trajectory according to the standard measurement trajectory and the offset; controlling a three-dimensional coordinate measuring machine to measure the component to be measured based on the current measurement trajectory to determine the component size of the component to be measured; determining the standard size of the component to be measured according to the component identification; determining the dimensional error between the component size and the standard size, and determining that the component to be measured is qualified when the dimensional error is determined to be within a preset error range. The above technical solution, after receiving the component identification and acquiring the standard component image of the component corresponding to the component identification, stores the component identification and the standard component image corresponding to the component identification accordingly, realizes the corresponding storage of the component identification and the component standard image, acquires the component image of the component to be tested based on the image acquisition device, and then determines the standard component image corresponding to the component image, and determines the standard component image corresponding to the component image in the standard component images corresponding to each component identification according to the component image, or determines the standard component image corresponding to the component image in the standard component images corresponding to each component identification according to the received component identification to be tested, and determines the component identification corresponding to the standard component image corresponding to the component image as the component to be tested. The component identification is determined according to the first center coordinate of the component image and the second center coordinate of the standard component image corresponding to the component image, the offset of the component image is determined, the standard measurement trajectory corresponding to the component identification is determined, and the standard measurement trajectory is adjusted according to the component image of the component to be measured and the offset of the standard component image corresponding to the component image, so as to obtain a current measurement trajectory for dimensional measurement of the component to be measured, and the three-dimensional coordinate measuring machine is controlled to measure the component to be measured based on the current measurement trajectory. Specifically, the measurement arm of the three-dimensional coordinate measuring machine can be controlled to move based on the current measurement trajectory to realize dimensional measurement of the component to be measured, obtain the component size of the component to be measured, and further realize automatic determination of a more accurate component size of the component to be measured.

[0097] Moreover, after determining the component identification of the component to be tested, the standard size of the component to be tested can also be determined based on the component identification, and then the dimensional error between the component size of the component to be tested and the standard size can be determined. When it is determined that the dimensional error is within a preset error range, the component to be tested is determined to be qualified, thereby achieving the qualification test of the component to be tested.
