Detailed Description

The technical scheme in the embodiment of the invention has the following general idea:

in this embodiment, a first image of a target module after shooting and dispensing is acquired, and the first image is aligned with a template image corresponding to a template module of the same model before dispensing, so that an actual dispensing position in the first image is aligned with an estimated dispensing position preset in the template image. And analyzing the aligned first image and the template image to obtain a dispensing detection result. On the one hand, avoided artifical detection's the hourglass to examine the problem, practiced thrift the human cost, on the other hand, all detect as the benchmark with the template image of template module owing to all shoot before not needing every module point of making a video recording to glue, improved detection efficiency.

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

The embodiment provides a method for detecting dispensing, as shown in fig. 1, including:

step S101, acquiring a first image of a shot and glued target module;

step S102, aligning the first image with a template image to align an actual dispensing area in the first image with an estimated dispensing area preset in the template image, wherein the template image is an image obtained by shooting a template module before dispensing, and the template module is a module of the same type as the target module;

step S103, analyzing the aligned first image and the template image to obtain a dispensing detection result.

It should be noted that the method for detecting dispensing can be applied to a computer, a tester, and other independent computing devices, and can also be applied to a detection module integrated on a test production line or a test machine, which is not limited herein and is not listed.

The target module may be a camera module, a distance measuring module, etc., and the detected glue may be the glue of the lens and the lens barrel, or the glue of the sensor and the frame, which are not limited herein.

Next, taking the template module and the template module as the camera module as an example, the implementation steps of the method provided in this embodiment are described in detail with reference to fig. 1:

firstly, a template image needs to be prepared in advance, and in order to ensure the matching of the template image and a module to be detected, the template image shot before dispensing by the template module with the same model as a target module to be detected is selected as the template image. For example, as shown in fig. 2, a template image is obtained by photographing the template module.

Preferably, in order to facilitate more accurate subsequent alignment, the pre-estimated dispensing area may be marked on the template image in advance, and specifically, the center line of the pre-estimated dispensing area and the boundary line of the area expected to be dispensed may be marked to ensure alignment. For example, as shown in fig. 3, when the lens and the lens barrel of the camera module are fixed by dispensing, the dispensing area is estimated to be a gap area between the screw teeth 31 of the camera module, and the screw teeth 31 are located between the lens barrel 32 and the lens 33. An imaging center O of the template module is marked on the template image in advance, a center line a and two boundary lines b of any pre-estimated dispensing area are marked, and a reference line c in the 12-point direction relative to the midpoint O can be marked on the image, so that subsequent accurate alignment is facilitated.

Then, step S101 is executed to obtain a first image of the shot dispensed target module.

Specifically, after the target module passes through a dispensing process on a production line, a picture of the target module is taken and acquired as a first image. Preferably, the angle and distance of the shooting target module are the same as or as much as possible with the angle and distance of the shooting template module, so as to facilitate subsequent alignment and analysis. For example, as shown in fig. 4, the first image of the target module after dispensing is taken, in which the black area 41 is the area where the glue is dispensed and is the gap area between the threads of the camera module.

And step S102 is executed, the first image is aligned with the template image, so that the actual dispensing area in the first image is aligned with the pre-estimated dispensing area preset in the template image.

Specifically, the actual dispensing area may be determined by performing a graphic feature analysis on the first image (for example, the graphic analysis identifies a gap area between the threads), and then the imaging center O ' of the target module in the first image and the center line a ' and two boundary lines b ' of any actual dispensing area may be aligned accurately for subsequent alignment.

Preferably, the imaging center of the target module in the first image may be aligned with the imaging center of the template module in the template image. And then, rotating the first image to align the actual dispensing area of the target module in the first image with the pre-estimated dispensing area preset by the template module in the template image. For example, the first image is first translated by X0-X1 pixels in the X-axis direction and by Y0-Y1 pixels in the Y-axis positive direction, so that the imaging center O' of the template module in the first image is aligned with the imaging center O of the template module in the template image. As shown in fig. 5, according to the angle difference between the actual dispensing area and the estimated dispensing area, the imaging center O' of the template module in the first image is used as the axis to rotate the first image so that the actual dispensing area and the estimated dispensing area are aligned and overlapped. The specific rotation angle may be determined according to any one of the pre-estimated center line a and two boundary lines b of the dispensing region marked before and the pre-estimated center line a 'and two boundary lines b' of the actual dispensing region marked before, for example, the rotation angle is equal to an included angle between the pre-estimated center line a of the dispensing region and the actual center line a 'of the dispensing region after aligning the imaging center O' of the target module in the first image with the imaging center O of the template module in the template image. Because the dispensing positions of the camera module are always uniformly and symmetrically distributed, after any actual dispensing area is aligned with the estimated dispensing area after rotation, other actual dispensing areas can be aligned with the area needing dispensing on the template image.

Of course, the method for aligning the first image with the template image is not limited to the above, and the first image and the template image may be directly defaulted to have no deflection, so that only center alignment is performed; the first image and the frame region imaged by the module in the template image can be aligned according to the frame after being subjected to pattern matching, which is not limited and is not listed.

Next, step S103 is executed to analyze the aligned first image and the template image, and obtain a dispensing detection result.

The two aligned images may be analyzed by performing a translucency process on the two images, placing the two images in an overlapping manner, and performing a manual analysis or an image characteristic analysis.

Preferably, the difference between the first image and the template image is calculated to obtain a difference image, and then the dispensing detection result is obtained according to the difference image. Specifically, calculating the difference between the first image and the template image may be comparing features of the two images, and extracting and displaying different image features on the difference image to obtain the dispensing detection result according to the difference image (for example, manually checking the difference image to obtain the dispensing detection result). Because the two images are before and after dispensing, the difference is the dispensing area, the difference is extracted to generate a difference image, the interference of other image areas is eliminated, and the rapid failure of the dispensing area and the dispensing condition can be helped.

Preferably, as shown in fig. 6, the difference image may be obtained by calculating a difference between the first image and the template image and performing binarization processing on the calculated difference data. Differences are highlighted through binarization, so that the dispensing area is easier to identify accurately.

Preferably, the method for obtaining the dispensing detection result according to the difference image may further comprise determining the number of dispensing areas of the target module and the dispensing amount data of each dispensing area according to the difference data represented by the difference image, and determining the dispensing detection result according to the number of dispensing areas and the dispensing amount data.

Specifically, as shown in fig. 7, the dispensing required area (the area within the fan-shaped frame in fig. 7) is preset, and then the number of dispensing areas of the target module and the area ratio of each dispensing area in the dispensing required area are determined according to the difference data (the white irregular stripe area in fig. 7) represented by the difference image and the dispensing required area. And then judging whether the quantity of the dispensing areas meets the preset quantity and whether the area ratio meets the preset ratio, and if so, determining that the dispensing detection result is qualified.

For example, in fig. 7, all the 4 predetermined dispensing areas have dispensing, and the area ratio of each dispensing area in the dispensing area is greater than the predetermined specification of 70%, the dispensing detection result of the template module is determined to be qualified.

Specifically, template images of the template modules are used as the reference, and the template modules of the same model are analyzed after being aligned, so that on one hand, the problem of missing detection of manual detection is avoided, the labor cost is saved, on the other hand, because each camera module is not required to be photographed before dispensing, the template images of the template modules are used as the reference for detection, and the detection efficiency is improved. In addition, after the first detection is unqualified and the reworking of the dispensing process is carried out, the reworked module can be detected by the dispensing detection method provided by the application.
