Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative only for the purpose of explaining the present invention, and are not to be construed as limiting the present invention.
Referring to fig. 1 and fig. 2, fig. 2 is a flowchart illustrating an embodiment of a level difference measurement method provided by an embodiment of the present invention, and for convenience of description, only a part related to the embodiment of the present invention is shown.
Specifically, the step difference measuring method specifically comprises the following steps:
and S101, controlling a camera to acquire a three-dimensional image of the detected part.
And S102, acquiring the step difference information of the measured part through the Z-axis data of the three-dimensional image.
S103, judging whether the step difference information is in an error range or not, and if not, prompting.
Specifically, as shown in fig. 1 and 2, in the production process of the tablet computer, a better transceiving quality can be achieved for the wireless antenna. The wireless antenna is installed in the antenna groove at one side of the tablet computer, so that after the wireless antenna is installed in the antenna groove, a step difference may be generated due to the installation accuracy problem, thereby affecting the beauty and quality of the product. Therefore, the part with the wireless antenna needs to be detected through a step difference detection mode so as to judge whether the installation of the wireless antenna meets the requirement or not through the detection result, and in step S101, a three-dimensional image of the detected part is acquired through controlling the camera; the three-dimensional camera is adopted to acquire the three-dimensional image of the detected part, and the three-dimensional image contains XY-axis and Z-axis information, so that the step difference information of the detected part can be acquired conveniently through the three-dimensional image; in step S102, step information of the measured portion is acquired from the Z-axis data of the three-dimensional image; the formed level difference information between the wireless antenna and the mounting groove can be extracted by the Z-axis data of the three-dimensional image. In step S103, it is determined whether the step information is within the error range, and if the step information is not within the error range, the step information is presented. Since the level difference is formed by the gap between the wireless antenna and the mounting groove, the level difference information corresponds to the gap condition around the antenna. That is, the level difference information may directly reflect the formed groove around the wireless antenna, such as the shape and size of the groove. And judging the level difference information to obtain whether the wireless antenna meets the requirement of installation precision. If the step difference information is in the error range, the installation of the wireless antenna meets the precision requirement, and the wireless antenna can be judged to be qualified. Otherwise, it indicates that the installation of the wireless antenna is out of tolerance. It is prompted to be disposed of as a defective product.
According to the step difference measuring method provided by the embodiment of the invention, the three-dimensional image of the measured part is obtained by controlling the camera; acquiring the step difference information of the measured part through the Z-axis data of the three-dimensional image; and judging whether the step difference information is in an error range, and prompting if the step difference information is not in the error range. The three-dimensional camera can acquire the three-dimensional data while acquiring the two-dimensional picture data of the segment difference part, and the position of the three-dimensional data is relatively fixed. Therefore, high-precision measurement of the segment difference part can be realized through the three-dimensional data, and the quality of a measured product is ensured.
Referring to fig. 1 and 3, the step of determining whether the level difference information is within the error range includes the steps of:
and S1031, respectively acquiring each level difference groove formed by the level difference according to the level difference information.
And S1032, judging the error range of each step groove.
S1033, if the size or the shape of one of the step difference grooves exceeds the error range, judging that the step difference information exceeds the error range.
Specifically, when the step difference information is acquired through the three-dimensional graph to determine the error, the step difference groove formed by the Z-axis data needs to be acquired through the Z-axis data of the three-dimensional graph. In step S1031, each level difference groove formed by the level difference is acquired according to the level difference information; such as a stepped groove formed by the both ends of the wireless antenna and the mounting groove shown in fig. 1. After obtaining each level difference groove, respectively judging the error range of each level difference groove through step S1032; specifically. Such as a step notch at both ends of the wireless antenna in fig. 1. After the wireless antenna is accurately installed, the grooves at the two ends of the wireless antenna are symmetrical, namely, the size and the shape are consistent. When the wireless antenna is installed with a deviation, the size of the groove with a section difference on one side is inconsistent with that of the groove with a section difference on the other side. In step S1033, if the size or the shape of one of the level difference grooves exceeds the error range, it is determined that the level difference information exceeds the error range. For example, as in the case of fig. 1, when the level difference on the left or upper side exceeds the error range, it can be judged that the level difference information exceeds the error range. Referring to fig. 1, in one embodiment of the present invention, the level difference groove includes: the groove is formed between the front, back, left and right peripheral areas between the mounting groove and the mounting component.
Referring to fig. 1 and 4, the level difference measuring method further includes the steps of:
and S204, processing according to the XY-axis image data of the three-dimensional image to acquire the contour information of the measured part.
And S205, acquiring each groove formed by the contour according to the contour information.
And S206, judging the error range of each groove.
And S207, if the size or the shape of one groove exceeds the error range, judging that the step difference information exceeds the error range.
Specifically, as shown in fig. 1 and 4, while the level difference groove is acquired by the Z-axis data of the three-dimensional image, the data of the XY-axis may also be acquired by the three-dimensional image, and the error of the level difference groove is further judged by the processing of the image data of the XY-axis to obtain an error judgment result according to precision. And step S204, processing according to the XY-axis image data of the three-dimensional image to acquire the contour information of the measured part. As shown in fig. 1, by processing the XY-axis image data, contour information similar to that in fig. 1 can be obtained. Passing the waiting information. Then, through S205, according to the contour information, obtaining each groove formed by the contour; for example, a stepped groove is formed at both left and right ends of the wireless antenna. After obtaining each step difference groove, respectively judging the error range of each groove through step S206; for example, the profile information of the stepped groove may be extracted, the extracted profile information may be compared with the profile information formed after standard installation one by one, and when an error between any one of the extracted profile information and the standard profile information exceeds a set range, it may be determined that the stepped information exceeds the error range through step S207 if the size or shape of one of the grooves exceeds the error range. By integrating the XY plane image error judgment result and the Z-axis data judgment result, the error judgment rate can be greatly improved, and the condition of erroneous judgment is avoided.
Referring to fig. 5, the method for processing the XY-axis image data of the three-dimensional image to obtain the contour information of the measured portion includes:
s2041, carrying out global binarization reprocessing on the XY axis image by using a global binarization algorithm.
S2042, carrying out noise elimination on the XY axis image after the global binarization reprocessing so as to remove an interference area on the XY axis image.
S2043, dividing the groove region in the XY axis image by a vertical projection method to obtain the peripheral boundary of each groove, and cutting out each groove.
Specifically, when processing an image, in order to better perform corresponding processing on the image, in step S2041, global binarization reprocessing is performed on the XY-axis image by using a global binarization algorithm; in this way, the image is converted into a binarization amount so as to implement correlation processing of the image by using an algorithm based on binarization. After the image is binarized, the noise of the image needs to be removed by the image noise removing method in step S2042. The image noise may be image noise caused by light interference or stain interference, and the noise may affect the acquisition of the peripheral boundary of the groove, causing a relatively large error problem. After the noise information in the image is eliminated, in step S2043, the groove region in the XY-axis image is divided by using a vertical projection method to obtain the peripheral boundary of each groove. Therefore, the boundary tracks of the grooves can be obtained, the grooves can be cut out through the boundary tracks of the grooves and the positions of the grooves in the image, and the judgment of groove errors is achieved.
