Description
Technical Field
The present application relates to the field of panel element detection technologies, and in particular, to a method and an apparatus for determining a shooting path for panel element detection, a computer device, a storage medium, and a computer program product.
Background
AOI (Automated Optical Inspection) Inspection equipment, also known as AOI Optical Automated Inspection equipment, has become an important Inspection tool and process quality control tool for ensuring product quality in the electronics manufacturing industry. AOI detection equipment principle: during automatic detection, the AOI detection equipment automatically scans PCBA products through a high-definition CCD camera, acquires images, compares the detected points with qualified parameters in a database, detects defects on target products through image processing, and displays/marks the defects through a display or an automatic mark for maintenance personnel to repair and SMT engineering personnel to improve the process.
Since the components on the panel to be measured are very small components and the area of the panel is very large, in order to retain more details to determine the defects of the component to be measured, the range of the object shot in each imaging process has to be narrowed when the image is collected. As shown in FIG. 1, to ensure the richness of the details of the components, each picture can only capture a range of box sizes. Therefore, the camera needs to be moved many times to complete the inspection of all the dut on the whole panel by photographing different areas of the panel. A common method is to scan the entire panel in a tiled fashion, as shown in fig. 2. To ensure that no element is missed, a certain overlap area is usually left between the pictures. The numbers in the figures represent the figure for this several scan.
However, tiled scanning may occur where one element appears in two captured images, resulting in more picture data and too much redundancy in picture resources. Moreover, each line of scan has a long operation of returning to the initial position of the line, which is physically a long distance, and thus takes a long time to affect the scanning efficiency.

Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In one embodiment, as shown in fig. 3, a shooting path determining method for panel element detection is provided, and this embodiment is exemplified by applying the method to a terminal, and it is to be understood that the method may also be applied to a server, and may also be applied to a system including a terminal and a server, and is implemented by interaction between the terminal and the server. In this embodiment, the method includes the steps of:
step S301, forming an original photographing region corresponding to each device to be measured by taking the position of each device to be measured on the panel as a region center, and obtaining a plurality of original photographing regions.
The position of each element to be measured on the panel and the physical range which can be shot by the area-array camera are known, and the shooting area refers to the physical position corresponding to the center of the picture when shooting each time. As shown in fig. 4, a plurality of original photographing regions are generated with the position of each device under test as the center of the photographing region. In the embodiment of the application, a shooting area, in which each component to be tested is located on a panel, is set as an area center and corresponds to a shooting range of a shooting device, and is used as an original shooting area corresponding to each component to be tested.
Step S302, taking the position of the to-be-measured element corresponding to each original shooting area as the movement constraint of the corresponding original shooting area, and moving each original shooting area to the preset direction of the plane where the panel is located, so as to obtain a plurality of initial shooting areas.
The width and height of a region of interest (ROI) corresponding to each device under test on the panel are known. As shown in fig. 5, on the basis of ensuring that the ROI of each dut on the panel is still in the shot region, the plurality of original shot regions are moved in the preset direction of the plane of the panel, so as to obtain a plurality of initial shot regions. In the embodiment of the present application, the plurality of original shot regions are moved to the upper right of the plane where the panel is located, so that the ROI of the component is located at the lower left corner of the shot region.
Step S303 is to move the plurality of initial imaging regions so that the region center of the moved initial imaging region coincides with the position center corresponding to the entire device under test included in the initial imaging region, thereby obtaining a plurality of candidate imaging regions.
As shown in fig. 6, the device to be measured that can include the complete ROI in each initial imaging region is found, and the initial imaging region is moved so that the region center of the initial imaging region coincides with the position center corresponding to all the devices to be measured included in the initial imaging region, thereby obtaining a plurality of candidate imaging regions.
Step S304, selecting a plurality of target shooting areas from a plurality of candidate shooting areas; the plurality of target shooting areas cover all the elements to be tested on the panel.
As shown in fig. 7, a plurality of target shot regions are selected from the plurality of candidate shot regions on the basis of ensuring coverage of the ROIs of all the devices under test on the panel.
In step S305, a shooting path is formed based on the plurality of target shooting regions according to the shooting path length constraint.
As shown in fig. 8, in order to shorten the total path length of photographing, a proper arrangement order is performed for a plurality of target photographing regions, thereby forming a final photographing path. Where the numbers in the figures represent the figure for this several scan. In the embodiment of the present application, the photographing path may adopt a serpentine path. The serpentine path can shorten the total path length of the shot compared to returning to the beginning of a line each time when shooting.
According to the shooting path determining method for panel element detection, the number of pictures to be shot is reduced, the shooting path is optimized, the scanning efficiency of the panel element is improved, and the panel detection efficiency is improved by reasonably designing, selecting and planning the positions of the pictures shot when the panel element is detected.
In one embodiment, the selecting a plurality of target photographing regions from the plurality of candidate photographing regions includes: and traversing each candidate shooting area of the plurality of candidate shooting areas according to a preset traversal priority order and element rejection conditions contained in the preset areas to obtain the plurality of target shooting areas.
In the embodiment of the present application, before traversing a plurality of candidate shooting regions, the candidate shooting regions may be sorted in a row-first order (corresponding to a preset traversal priority order). Then, the obtained plurality of candidate photographing regions are sequentially traversed one by one. Wherein, for the first target shooting area: when traversing to a candidate shooting area covering the most elements to be tested, taking the candidate shooting area as a first target shooting area; for the non-first target shooting area, when the elements to be tested contained in the traversed subsequent shooting areas are not contained in other areas in the selected target shooting area (corresponding to element exclusion conditions contained in the areas), the traversed candidate shooting areas are used as the target shooting areas, and by analogy, after all the candidate shooting areas are traversed in sequence, a plurality of target shooting areas are obtained.
In one embodiment, the photographing path determining method for panel element detection further includes: if the target shooting areas can not cover all the elements to be tested on the panel, the target shooting areas are selected from the candidate shooting areas in a supplementing mode based on a preset panel residual element covering condition; the complementary selected target shooting area covers the rest elements on the panel and is partially overlapped with the selected target shooting areas.
As shown in fig. 9, after traversing the plurality of candidate capturing areas, part of the devices to be tested still cannot be covered by the target capturing area, that is, the plurality of target capturing areas cannot cover all the devices to be tested on the panel. At this time, the target photographing region needs to be selected from the plurality of candidate photographing regions, so that the finally obtained target photographing region can cover all the devices to be tested on the panel. As shown in fig. 7, the target capture area selected in the supplementary manner not only needs to cover the dut already covered in the target capture area after traversal, but also covers as many duts as possible (corresponding to the panel remaining device coverage condition) that are not covered in the target capture area after traversal.
In order to obtain the total number of pictures taken as small as possible and the total length of paths traversing all the photographing positions in sequence as short as possible under the condition that the position of each element to be measured on the panel, the width and the height of the ROI corresponding to each element to be measured and the width and the height of a physical range capable of being photographed by an area-array camera are known, in an application example, the application provides a photographing path determining method for panel element detection, and the specific flow comprises the following steps:
in a first step, a set S of candidate shooting positions with a limited number of elements is generated. Specifically, a shooting area which takes the position of each element to be tested on the panel as an area center and corresponds to the shooting range of the shooting equipment is obtained and is used as an original shooting area corresponding to each element to be tested, and a plurality of original shooting areas are obtained; taking the position of the element to be detected corresponding to each original shooting area as the movement constraint of the corresponding original shooting area, and moving each original shooting area to the upper right of the plane where the panel is located to obtain a plurality of initial shooting areas; and moving the plurality of initial shooting areas so that the area center of the moved initial shooting area coincides with the position center corresponding to all the elements to be measured included in the initial shooting areas, thereby obtaining a plurality of candidate shooting areas. The set of the plurality of candidate shooting areas is the candidate shooting position set S.
In the second step, all the shooting position sets P to be used are obtained. That is, a subset P is always selected from the candidate capturing position set S to ensure that the capturing regions corresponding to all the capturing positions in P can cover the ROIs of all the components to be measured. Specifically, the plurality of candidate photographing regions are sorted in the order of line priority; traversing a plurality of candidate shooting areas one by one according to element rejection conditions contained in preset areas to obtain a plurality of target shooting areas; and if the target shooting areas can not cover all the elements to be tested on the panel, complementarily selecting the target shooting areas from the candidate shooting areas based on a preset panel residual element covering condition, wherein the complementarily selected target shooting areas cover the residual elements on the panel and are partially overlapped with the selected target shooting areas.
And thirdly, finding a shooting sequence to make the total path length of all shooting positions in the traversal set P shorter. Specifically, in order to shorten the total path length of photographing, a photographing path is formed based on a plurality of target photographing regions using a snake walk.
In the above example, the redundancy of the shot images can be greatly reduced, the utilization rate of each image is improved, the detection efficiency of the whole panel is improved, the path of the shot images is reasonably planned, and the whole image acquisition time is further optimized on the basis of less image quantity.
It should be understood that, although the steps in the flowcharts related to the embodiments as described above are sequentially displayed as indicated by arrows, the steps are not necessarily performed sequentially as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
