Fig. 2 is a kind of schematic diagram of circuit board.As it can be seen that circuit board, which may include, multiple element 201, Duo Geyuan in figure Part 201 can be distributed on each position of circuit board.

Fig. 3 is a kind of schematic diagram of the circuit board detecting method of the prior art.There are one the filming apparatus tools of detection device Field angle FOV carries out image taking, and be directed to by field angle FOV to the region being in circuit board in field angle FOV The image of shooting is detected.When detecting, circuit board can be in advance divided into multiple regions 301, the model in each region 301 It encloses identical as the range of a field angle FOV.When filming apparatus carries out image taking, shot within the scope of its field angle FOV Image, you can obtain the image in one of circuit board region.Filming apparatus moves field angle FOV, you can takes circuit The image of the multiple regions 301 of plate, detection device are detected the image in multiple region 301, you can complete to circuit board Whole elements detection.

With the example of Fig. 3, illustrate that the circuit board detecting method of the prior art has that detection efficiency is relatively low.Fig. 3 In element 302 be distributed in four regions 301, therefore, detection device needs four regions 301 are shot respectively, And be detected for four images, the detection to element 302 could be completed, detection efficiency is relatively low.

Specifically, with reference to figure 1, circuit board detecting method provided in this embodiment specifically includes：

Step S101 obtains N number of prime area；N number of prime area covers whole element characteristics of circuit board.

Wherein, above-mentioned N number of prime area can be the multiple regions for dividing circuit board according to preset rules. For example, can more parts be divided into the length and width of circuit board, according to a length and a width as a region, from And circuit board is divided into N number of region.

Wherein, above-mentioned element characteristics can be the feature of the electronic component on circuit board.For example, having on circuit board Electronic component, after circuit board is divided into multiple regions, the filming apparatus of detection device is shot for region, is obtained May include the characteristics of image of electronic component in image, it can be using the characteristics of image of electronic component as an element characteristics. In practical applications, it can be divided into multiple grid for circuit board, may include that there are one complete in the range of a grid Electronic component, can include the characteristics of image of complete electronic component by grid, as an element characteristics；One grid In the range of, it is also possible to include only local electronic component, it can also be by electronic component local included in grid Characteristics of image, as an element characteristics.

In the specific implementation, detection device, which can be directed to circuit board, divides N number of region, as above-mentioned N number of prime area.Electricity There can be multiple element feature on the plate of road, N number of prime area can be covered with whole element characteristics on circuit board.

Fig. 4 is the schematic diagram of N number of prime area of the embodiment of the present invention one.It can be seen that circuit board can be divided For 4 prime areas, respectively prime area 401, prime area 402, prime area 403 and prime area 404.4 initial In region, it is covered each by element characteristics E01, element characteristics E02, element characteristics E03 and element characteristics E04.

Step S102 determines M target area according to N number of prime area and its element characteristics of covering；The M A target area covers whole element characteristics of N number of prime area covering；Wherein, N > M > 0.

In the specific implementation, the element characteristics that can be covered according to prime area, at the beginning of moving one in N number of prime area Beginning region or multiple prime areas.At mobile prime area, can be moved to the target of setting based on the edge of element characteristics Direction is moved, when some or multiple prime areas after movement, the whole elements for being covered with another prime area are special Sign, it may be determined that another prime area is the prime area of a redundancy, if using the prime area of redundancy as target area Domain is detected, then can be detected to identical element characteristics, reduce detection efficiency.It therefore, can be by the initial of redundancy It deletes in region.After the prime area of redundancy is deleted, using remaining prime area as target area, thus obtains quantity and be less than The M target area of N.For example, for 12 prime areas, after mobile 2 prime areas, 2 target areas are obtained, this 2 Target area covers the whole element characteristics for the prime area that 1 is not moved, determines that it is the prime area of redundancy, by redundancy Prime area delete and need not be mobile, continue to move remaining 9 prime areas, obtain 9 target areas, finally 11 target areas are obtained.

Fig. 5 is a kind of schematic diagram of mobile prime area of the embodiment of the present invention one.It can be seen that being divided in circuit board There are prime area 501, prime area 502, prime area 503 and prime area 504.Current prime area 501, prime area 502, prime area 503 and prime area 504, be covered each by element characteristics E01, element characteristics E02, element characteristics E03 and Element characteristics E04.

Prime area 501 is chosen to be moved, prime area 501` is obtained, using prime area 501` as a mesh Mark region 505.Target area 505 covers the element characteristics E02 of prime area 502, and there are one element spies for prime area 502 Levy E02, that is, target area 505 covers whole element characteristics of prime area 502.Similarly, target area 505 covers just Whole element characteristics in beginning region 503, target area 505 covers whole element characteristics of prime area 504.It therefore, can be with Determine that prime area 502, prime area 503 and prime area 504 are the prime area of redundancy, delete prime area 502, just Beginning region 503 and prime area 504.Finally, the target area for whole element characteristics that one is covered with multiple prime areas is obtained Domain 505.

In practical application, it can judge that some prime area is according to the incidence relation between element characteristics and prime area No redundancy.Specifically, can circuit board be divided into multiple positioning lattices first, the feature in multiple positioning lattices is obtained, when some The feature of positioning lattice includes the feature of the completed element of circuit board, alternatively, including the feature of local element, then by this feature As an element characteristics, meanwhile, set the area identification of N number of prime area, by a prime area element characteristics with The area identification of the prime area establishes incidence relation.At a mobile prime area, searched from first in the prime area The edges of regions in beginning region is nearest and associated element characteristics of area identification with the prime area, as location feature, base Prime area is moved in the location feature, by the prime area after movement, as a target area, when the target area covers The element characteristics for having another prime area, by the element characteristics of another prime area covered, as a weight Area identification associated by re-association feature is revised as the area identification of target area by linked character, when another is initial Among the element characteristics of region overlay, there is no have with the associated element characteristics of the area identification of another prime area, Show that whole element characteristics of another prime area are covered by target area, it is possible to determine that another is initial Region is the prime area of redundancy.

With reference to figure 5, prime area 501, prime area 502, prime area 503 and prime area 504 are respectively provided with region Identify S01, S02, S03 and S04.Currently, area identification S01 is associated with element characteristics E01, area identification S02 and element characteristics E02 is associated with, and area identification S03 is associated with element characteristics E03, and area identification S04 is associated with element characteristics E04.

Prime area 501 is chosen to be moved, determines and is covered with element characteristics E01, element characteristics in prime area 501 E01 is associated with the area identification S01 of prime area 501, therefore, is moved prime area 501 based on element characteristics E01, is obtained just Beginning region 501`, using prime area 501` as target area 505, the area identification of target area 505 is all S01.Target Region 505 covers the element characteristics E02 of prime area 502, by the associated area identifications of element characteristics E02, from area identification S02 is revised as the area identification S01 of target area 505.Similarly, target area 505 covers the element characteristics of prime area 503 E03, and, the element characteristics E04 of prime area 504 is covered, therefore, by the associated area identifications of element characteristics E03, modification The associated area identifications of element characteristics E04 are revised as area identification S01 for area identification S01.

Then, prime area 502 is chosen, since related element spy is not present in the area identification S02 of prime area 502 Sign, shows that whole element characteristics of prime area 502 are covered by target area, therefore, it is possible to determine that prime area 502 be the prime area of redundancy, deletes prime area 502.Similarly, prime area 503 and 504 can be deleted, finally, obtains one A target area 505.

It should be noted that the square example of above-mentioned determining target area is merely to illustrate the technical thought of the present embodiment, this Field technology personnel can determine target area, the present embodiment according to technical thought provided in this embodiment using various ways To determining that the concrete mode of target area is not restricted.

Step S103 obtains M area image of the circuit board；The M area image and the M target area It corresponds.

Wherein, area image is that the filming apparatus of detection device is directed to the figure that the target area of circuit board is shot Picture.

In the specific implementation, after determining M target area, detection device can be directed to M target area of circuit board It is shot, obtains M area image, which includes whole element characteristics of circuit board.

Step S104 detects the element characteristics in the M area image.

In the specific implementation, the M area image includes whole element characteristics of circuit board, for the M area image It is detected, you can be detected with whole element characteristics for circuit board.

With reference to figure 5, the area image of target area 505 is obtained, which is detected, you can to complete to member Part feature E01, element characteristics E02, element characteristics E03 and element characteristics E04 are detected, and need not be respectively to prime area 501, prime area 502, prime area 503 and the area image of prime area 504 corresponding four are detected, and improve circuit Plate detection efficiency.

Technical solution provided in this embodiment, by for N number of prime area of circuit board and its element characteristics of covering, Quantification is less than the M target area of N, obtains the corresponding M area image in M target area, and detect M area image Element characteristics, to without obtaining N number of area image for N number of prime area and being detected to N number of area image, subtract Lack the area image for needing to detect, improves the efficiency of circuit board detecting.
