Description

Technical Field

[0001] The present invention relates to the field related to computer vision technology, and in particular to a computer vision detection auxiliary device and an auxiliary detection method. Background Art

[0002] Visual inspection is to use machines to replace human eyes to make measurements and judgments. Visual inspection refers to the process of converting the captured target into image signals through machine vision products (i.e. image capture devices, which are divided into CMOS and CCD), and transmitting them to a dedicated image processing system, which converts them into digital signals based on pixel distribution, brightness, color and other information.

[0003] The image system performs various operations on these signals to extract the characteristics of the target, and then controls the operation of the equipment on site based on the results of the judgment. It is a valuable mechanism for production, assembly or packaging. It has immeasurable value in detecting defects and preventing defective products from being delivered to consumers.

[0004] In some cases where motion detection is required, it is usually necessary to supplement light for the detection object to avoid shadows on the detection object.

DETAILED DESCRIPTION

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] In addition, when an element in the present invention is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and are not intended to be the only embodiment.

[0050] For example, see Figures 1 to 10A computer vision inspection auxiliary device comprises a workbench 1 and two brackets 2 fixed on the workbench 1, a support rod 3 is fixed between the two brackets 2, a steering gear 7 is adjustably mounted on the support rod 3, and a shooting camera 36 is rotatably mounted at the bottom of the steering gear 7; a plurality of legs are fixed at the bottom of the workbench 1, a limiting strip 8 is circumferentially fixed on the support rod 3, the steering gear 7 is slidably connected to the limiting strip 8, and the limiting strip 8 is limited by the steering gear 7;

[0051] A slide plate 4 is slidably mounted on the workbench 1, a turntable 5 is rotatably mounted on the slide plate 4, a linkage component is installed between the slide plate 4 and the workbench 1, and the linkage component is connected to the turntable 5;

[0052] Two support plates 29 are rotatably mounted on the workbench 1, and the two support plates 29 are located on both sides of the skateboard 4. Spotlights 6 are fixed on the two support plates 29. The support plates 29 are connected to the rotating shafts of the skateboard 4 and the shooting camera 36 through a transmission mechanism. A driving assembly connected to the skateboard 4 is installed on the workbench 1.

[0053] In the embodiment of the present invention, the model is placed on the turntable 5, and then the drive assembly is started;

[0054] When the driving assembly is working, the slide plate 4, the turntable 5 and the model on the turntable 5 are driven to move at a uniform speed along the length direction of the workbench 1;

[0055] The slide plate 4 drives the two support plates 29 and the spotlight 6 to rotate relative to each other through the transmission mechanism to adjust the rotation angle, and the model is supplemented with light by adjusting the illumination angle of the two spotlights 6. When the slide plate 4 moves, the transmission component also drives the rotating shaft of the shooting camera 36 to rotate, thereby turning the shooting camera 36 to ensure that the shooting camera 36 can clearly collect the graphic information of the model.

[0056] Specific sports information is as follows:

[0057] When the model moves toward the shooting camera 36, ​​the two spotlights 6 rotate relative to each other to adjust the illumination angle while the shooting camera 36 flips, so that the focus of the shooting camera 36 is on the model, and the model is collected from near to far, and the fill light of the two spotlights 6 always follows;

[0058] It can be seen in the figure that the camera 36 is in the middle position of the workbench 1. For example, when the model moves from the right side to the left side, but when the model moves to the bottom of the camera 36, ​​the steering gear 7 drives the camera 36 to rotate, so that the subsequent movement of the camera 36 is flipped in the opposite direction.

[0059] The linkage mechanism can realize that when the slide plate 4 moves, the turntable 5 rotates while following the rotation of the slide plate 4 .

[0060] Embodiment 2: The distinguishing feature from Embodiment 1 is that the transmission mechanism includes a sixth gear 30 and a seventh gear 31 coaxially fixed on the support plate 29, the sixth gear 30 is connected to the skateboard 4 through an intermittent transmission assembly, the seventh gear 31 is connected to an adjustment assembly installed on the support plate 29, and the adjustment assembly is connected to the rotating shaft of the shooting camera 36.

[0061] In the embodiment of the present invention, when the slide plate 4 is driven to move by the driving assembly, the support plate 29 is driven to rotate intermittently and slightly by the intermittent transmission assembly to adjust the illumination angle of the spotlight 6 on the support plate 29. When the support plate 29 rotates, the seventh gear 31 also drives the shooting camera 36 to flip through the adjustment assembly;

[0062] Among them, in addition to adjusting the illumination angle of the spotlight 6 when the support plate 29 rotates, the pitch angle of the spotlight 6 can also be manually adjusted to cope with models of different sizes.

[0063] The intermittent transmission assembly includes a driving disk 24 rotatably mounted on the workbench 1, the edge of the driving disk 24 is fixed by a fourth gear 25, and the driving disk 24 cooperates with a first rack 16 fixed to one side of the slide plate 4 through the fourth gear 25;

[0064] The first rack 16 is arranged in sections; the section arrangement here means that the first rack 16 includes two sections, and there is a certain distance between the two ends;

[0065] A locking plate 26 is coaxially fixed on the driving plate 24, and a transmission shaft 27 is also fixed at the eccentric part of the driving plate 24. The transmission shaft 27 and the locking plate 26 cooperate with a driven plate rotatably mounted on one side of the driving plate 24. A fifth gear 28 is coaxially fixed on the driven plate, and the fifth gear 28 is meshed with the sixth gear 30. The driving plate 24, the locking plate 26, the transmission shaft 27, and the driven plate are the movements of the Maltese cross movement in the prior art, and therefore are prior art and will not be elaborated on again.

[0066] In the embodiment of the present invention, when the slide plate 4 moves along the length direction of the workbench 1, the meshing of the first rack 16 and the fourth gear 25 drives the active disk 24 to rotate. When the active disk 24 rotates, the locking disk 26 is driven to rotate, and the transmission shaft 27 is driven to rotate in a circle with the rotation axis of the active disk 24 as the center. When the transmission shaft 27 rotates to match with the driven disk, the driven disk is driven to rotate. When the transmission shaft 27 is disengaged from the driven disk, the driven disk stops rotating, and at the same time, the locking disk 26 is used to apply self-locking to the slave side, so that the driven disk cannot rotate when the transmission shaft 27 is disengaged from the slave disk. In short, the active disk 24 rotates one circle and drives the slave side to rotate a quarter.

[0067] When the driven plate rotates, the coaxially fixed fifth gear 28 drives the sixth gear 30 to rotate, and the sixth gear 30 drives the support plate 29 to rotate;

[0068] like Figure 1 As shown, the first rack 16 is arranged in sections. When the fourth gear 25 is between two sections of the first rack 16, the first rack 16 and the fourth gear 25 are in a state of being out of transmission relationship. During this process, the servo 7 is given movement time. After the servo 7 completes its work, as the components of the skateboard 4 move, the first rack 16 and the fourth gear 25 are meshed again to complete the subsequent movement.

[0069] The adjustment assembly includes a support platform 34 fixed on the workbench 1, and an eighth gear 32 is rotatably mounted on the bottom of the support platform 34, and the eighth gear 32 is meshed with the seventh gear 31;

[0070] A second gear 11 is rotatably mounted on one side opposite to the two brackets 2, and a second transmission rod 13 is rotatably mounted on one side opposite to the two brackets 2. The second transmission rod 13 is connected to the rotating shaft of the second gear 11 via a bevel gear set 12, and the second transmission rod 13 is connected to the rotating shaft of the eighth gear 32 via a transmission chain 33; two limiting rollers 35 for limiting the transmission chain 33 are rotatably mounted on the support platform 34, and the transmission chain 33 is limited by the limiting rollers 35, so that there is no interference between the second transmission rod 13 and the eighth gear 32 connected via the transmission chain 33;

[0071] The two second gears 11 are both matched with the rotating shaft of the shooting camera 36 through a transmission member.

[0072] In the embodiment of the present invention, since the two active disks 24 are located on both sides of the slide plate 4, the two active disks 24 rotate relative to each other, and the corresponding two support plates 29 also rotate relative to each other;

[0073] When the support plate 29 rotates, while the two spotlights 6 rotate relative to each other, the eighth gear 32 is driven to rotate through the seventh gear 31. When the eighth gear 32 rotates, the second transmission rod 13 is driven to rotate through the transmission chain 33. Then, the second transmission rod 13 drives the second gear 11 to rotate through the bevel gear set 12. The cooperation between the second gear 11 and the transmission member drives the camera 36 to rotate, and then drives the camera 36 to flip. Since the two support plates 29 rotate relative to each other, the rotation directions of the two second gears 11 are opposite.

[0074] The transmission member includes a reinforcement frame 37 fixed to one side of the servo 7, and a third transmission rod 38 is rotatably mounted on the reinforcement frame 37. The third transmission rod 38 is coaxially fixed with the rotating shaft of the shooting camera 36. The first transmission rod 10 is coaxially fixed to one end of the third transmission rod 38 away from the rotating shaft of the shooting camera 36, ​​and the first transmission rod 10 cooperates with the second gear 11; the bevel gear set 12 includes two bevel gears meshing with each other, and the two bevel gears are coaxially fixed with the second transmission rod 13 and the third transmission rod 38 respectively.

[0075] In the embodiment of the present invention, for the convenience of description, the two second gears 11 are respectively named as the first gear and the second gear;

[0076] When the first transmission rod 10 is meshed with the No. 1 gear, the No. 1 gear drives the first transmission rod 10 and the first gear 9 to rotate, and the angle of the shooting camera 36 in one direction is adjusted by the rotation of the first gear 9. In the process of driving the shooting camera 36 to rotate 180° by the steering gear 7, the reinforcement frame 37 and the third transmission rod 38 are driven to rotate accordingly. At this time, the first gear 9 is disengaged from the No. 1 gear and meshed with the No. 2 gear, and then the first transmission rod 10 is driven to rotate in the opposite direction by the No. 2 gear, so that the angle of the shooting camera 36 is adjusted in the opposite direction by the reverse rotation of the first gear 9;

[0077] This process is completed when the fourth gear 25 is between the two sections of the first rack 16, that is, when the fourth gear 25 is out of mesh with the two sections of the first rack 16;

[0078] The movement process is that when the model moves toward the shooting camera 36, ​​the shooting camera 36 gradually adjusts the downward angle. When the shooting camera 36 rotates 180°, the model moves away from the shooting camera 36. At this time, the shooting camera 36 adjusts the upward angle.

[0079] It should also be noted that the reinforcement frame 37 in this embodiment provides a certain friction force to the third transmission rod 38 so that the third transmission rod 38 will not rotate due to the gravity of the shooting camera 36 when the third transmission rod 38 is driven by an external force.

[0080] The driving assembly includes a third gear 15 rotatably mounted on the workbench 1, and a second rack 17 meshing with the third gear 15 is fixed on the slide plate 4;

[0081] A motor 14 is fixed at the bottom of the workbench 1, and the output shaft of the motor 14 is coaxially fixed with the third gear 15; wherein, the motor 14 in this embodiment adopts a servo motor that can rotate clockwise / counterclockwise. Of course, a stepper motor or a DC motor, etc. can also be used. This application is specific and meets the driving requirements.

[0082] In the embodiment of the present invention, when the motor 14 is working, the output shaft drives the third gear 15 to rotate. When the third gear 15 rotates, the second rack 17 drives the slide plate 4 to move along the length direction of the workbench 1.

[0083] Embodiment 3: The distinguishing feature from Embodiment 1 and / or Embodiment 2 is that: the linkage assembly comprises an assembly groove starting from the workbench 1, a rack plate 21 is slidably mounted in the assembly groove, and the rack plate 21 is slidably matched with a spring sheet 22 fixed in the assembly groove at a side away from the teeth;

[0084] A ninth gear 39 is coaxially fixed to the bottom of the rotating disk 5, and the ninth gear 39 cooperates with the rack plate 21;

[0085] The spacing between the teeth of the rack plate 21 is equal to the radius length of the ninth gear 39 .

[0086] The workbench 1 is also rotatably mounted with a screw rod 20 that penetrates the workbench 1 and is rotatably connected to the workbench 1. Both ends of the screw rod 20 are provided with threaded portions, and the two threaded portions have opposite thread directions.

[0087] Both ends of the screw rod 20 are sleeved with a transmission plate 18 threadedly matched therewith, and the transmission plate 18 is slidably installed at both ends of the workbench 1 through a guide rod 19. The two transmission plates 18 are provided with a wedge block 23 integrally formed therewith on the opposite side, and the wedge block 23 cooperates with the rack plate 21.

[0088] In the embodiment of the present invention, when the slide plate 4 moves, the turntable 5 and the ninth gear 39 are driven to follow the movement. When the teeth of the ninth gear 39 move to contact the teeth of the rack plate 21, the support plate 29 is slightly rotated by a certain angle, and then the turntable 5 and the model on the turntable 5 are driven to rotate by the rotation of the support plate 29.

[0089] The turntable 5 rotates at equal angles intermittently with a short intermittent time. The purpose of the intermittent rotation is to give the shooting camera 36 sufficient time to collect information.

[0090] Under normal conditions, the spring sheet 22 is larger than the rack plate 21 to fix the rack plate 21, so that the rack plate 21 is not in the movement path of the support plate 29, and the support plate 29 does not cooperate with the rack plate 21 when rotating, and the support plate 29 and the turntable 5 do not rotate;

[0091] When the turntable 5 needs to rotate, the screw rod 20 is driven to rotate by an external force. When the screw rod 20 rotates, it drives the two transmission plates 18 to move relative to each other / oppositely by cooperating with the thread of the transmission plate 18. When the transmission plates 18 move relative to each other, the wedge block 23 is driven to move synchronously. The rack plate 21 is driven to move in a direction away from the spring sheet 22 by the inclination of the wedge block 23, and the spring sheet 22 is deformed to reserve a certain elastic potential energy, so that the spring sheet 22 moves into the movement path of the support plate 29, so that the support plate 29 can cooperate with the spring sheet 22 and rotate when moving along the path;

[0092] Similarly, when the two wedge blocks 23 are driven toward opposite directions, the rack plate 21 is driven to reset by releasing the elastic potential energy of the spring sheet 22;

[0093] It should also be noted that the spring sheet 22 in this embodiment can be replaced by other elastic materials / structures.

[0094] The present invention also provides a computer vision-assisted detection method, which uses the computer vision detection auxiliary device and includes the following steps:

[0095] Step 1: driving the slide plate 4 to move along the length direction of the workbench 1 by the driving assembly;

[0096] Step 2: When the slide plate 4 moves, the transmission mechanism drives the two spotlights 6 to rotate relative to each other for fill light, and at the same time drives the shooting camera 36 to adjust the pitch angle, so that the shooting camera 36 can complete the image and contour acquisition of the model on the turntable 5 from far to near;

[0097] When the model is at the other side and moves in a direction away from the shooting camera 36, ​​the other side of the model is captured from near to far;

[0098] The linkage assembly drives the turntable 5 and the model to rotate intermittently during the movement;

[0099] Step 3: When the model moves from one side of the workbench 1 to the other side, the image is collected.

[0100] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
