As shown in fig. 1, this embodiment provides a mechanical arm feeding system based on visual positioning in xiLin bottle inspection industry, this feeding system sets up in the terminal of guipure 5, and feeding system is used for carrying out the material loading to the inspection machine, and feeding system includes: the device comprises an image acquisition device 1, an identification positioning device, a manipulator 2 and a tail end clamp 3; the image acquisition device 1 is arranged above the mesh belt 5, and the image acquisition device 1 is used for acquiring images of penicillin bottles on the mesh belt 5; the recognition and positioning device is configured to recognize a bottle body bright band in the image, recognize a bottle mouth bright band in predicted areas on two sides in the length direction of the bottle body bright band, and determine the coordinate position of the penicillin bottle on the mesh belt 5 according to the bottle body bright band and the bottle mouth bright band when judging that one of the two predicted areas has the bottle mouth bright band; the stiff end of manipulator 2 passes through base 6 and sets up in the end of guipure 5, and sucking disc 507 is installed to the free end of manipulator 2, and manipulator 2 is used for driving sucking disc 507 and removes to the coordinate position to adsorb xiLin bottle on the coordinate position, manipulator 2 still is used for removing to the material loading region of inspection machine, and releases absorbent xiLin bottle.
Specifically, the feeding system mainly comprises an image acquisition device 1, an identification and positioning device and a manipulator 2. This image acquisition device 1 is mainly by the industry camera, the camera lens, image processing module constitutes, can also set up supporting light source and adjust support 20, keep apart guardrail 4, manipulator base 6 etc, wherein, industry camera can select big permanent planet camera, the camera lens is the Computar tight shot, the light source is 8 integrative high brightness LED fluorescent tubes 10 of T8, it makes 8 LED fluorescent tubes 10 become two-layerly on the space to adjust support 20, criss-cross distribution, and can realize around the regulation on left and right sides and the angle, can also set up the support guard shield simultaneously, this guard shield adopts dark brown transparent organic glass panel, provide sufficient effectual lighting condition for the image acquisition of camera.
After acquiring the penicillin bottle image on the mesh belt 5, the image acquisition device 1 cannot accurately identify the edge, texture and other characteristics of the penicillin bottle in the image, so that the transparent penicillin bottle cannot be positioned. Through the research on the characteristics of the complete penicillin bottles in the images, the common characteristic of each complete transparent penicillin bottle is that the bottle body and the bottle mouth both contain a complete reflection light band.
Therefore, in order to identify a complete transparent vial, the embodiment introduces identification of the reflection light bands at the vial body and the vial mouth, i.e., the premise of identifying a complete vial is that the vial body and the vial mouth need to have a complete reflection light band respectively. Simultaneously, in order to guarantee that every xiLin bottle can both demonstrate relatively complete light band in the camera, can synthesize according to the condition in xiLin bottle reflection light band that the direction is different, adjust 8 with the LED fluorescent tube 10 the locating position on adjusting support 20, concrete adjustment process is no longer repeated.
The identification and positioning device in the embodiment is configured to identify a bottle bright band in an image according to a preset light band length, identify a bottle mouth bright band in predicted areas on two sides of the bottle bright band in the length direction, and determine a coordinate position of the penicillin bottle on the mesh belt 5 according to the bottle bright band and the bottle mouth bright band when it is determined that one of the two predicted areas has the bottle mouth bright band, wherein the coordinate position at least comprises a bottle body coordinate and a bottle body angle, the bottle body coordinate is a center position coordinate of the bottle body bright band, and the bottle body angle is determined by a trigonometric function according to the center position coordinate of the bottle body bright band and the center position coordinate of the bottle mouth bright band.
Specifically, before the recognition, a detection area is first drawn by the grasping area of the manipulator 2 and the discharge position of the vial, and the detection area is used as a target recognition area. Then, a threshold segmentation algorithm is adopted to segment the reflection bright band of the bottle body and the bottle mouth so as to achieve the purpose of positioning the transparent penicillin bottle, wherein the corresponding calculation formula is as follows:
in the formula, Gray (x, y) represents a Gray value at coordinates (x, y) in an image, Threshold represents a Threshold, and Gray (x, y) represents a Gray value after Threshold division. That is, in the image after the threshold division, the region in which the Gray value Gray (x, y) is 1 is the identified reflection band.
Then, the bottle body bright band in the reflection light band can be screened out according to the preset light band length, a certain distance is respectively extended to two sides along the length direction (the bottle body direction) of the bottle body bright band, an expected area is determined, a threshold segmentation algorithm is also adopted to detect whether a reflection bright band of a bottle opening exists in the two extended areas, namely the bottle opening bright band, wherein the distance between the expected area and the bottle body bright band can be manually set according to the length specification parameters of the transparent penicillin bottle.
It should be noted that, based on the preset light band length representing the bright band length of the bottle body, the defective penicillin bottles (such as half-cut bottles, short bottles and long bottles) on the net belt 5 can be screened, and the reflected light band with the length not meeting the preset light band length is not identified, so that preliminary penicillin bottle quality detection is realized. Wherein the preset optical band length comprises a low threshold and a high threshold to indicate a length range.
As shown in fig. 2, if the bright band of the bottle mouth is found only in one predicted area, the body coordinate and the body angle of the vial can be calculated according to the relative positions of the bright band of the bottle mouth and the bright band of the body, and the body coordinate and the body angle are sent to the manipulator 2 as coordinate position information, wherein the calculation formula of the body angle is as follows:
in the formula, theta is a bottle body angle, (x1, y1) is a bottle body coordinate, namely a central position coordinate of a bottle body bright band, and (x2, y2) is a central position coordinate of a bottle opening bright band.
Further, the identification positioning device is further configured to: and when judging that the bottle mouth bright bands exist in the predicted areas on the two sides of the bottle body bright band, or when judging that the bottle mouth bright bands do not exist in the predicted areas on the two sides of the bottle body bright band, identifying the next bottle body bright band in the image.
Specifically, if bright areas of the bottle openings are found in the two predicted areas, the bottle opening of one penicillin bottle is considered to be close to the bottom of the other penicillin bottle, at the moment, in order to avoid interference of the adjacent penicillin bottles, the penicillin bottle is temporarily selected not to be identified and not to be grabbed, the bright area of the next bottle body in the image is identified, and the penicillin bottle is identified after the interfered penicillin bottle is sucked away;
and if the bottle mouth bright band is not found in the two predicted areas, the penicillin bottle corresponding to the bottle body bright band is considered to be a tube head without the bottle mouth, grabbing is not needed, and the next bottle body bright band in the image is identified.
It should be noted that, on the premise of better identifying the vial, the position compensation (including row coordinates and column coordinates) to be added can be adjusted by observing the position deviation of the manipulator 2 for grabbing the vial and the movement of the mesh belt 5, and the coordinate position determined by the identifying and positioning device is compensated, so as to achieve the effect of accurately grabbing the vial.
Further, the number of suction cups 507 is at least two, and the robot 2 is configured to: judging whether the adjacent area of the second to-be-grabbed penicillin bottle has an intersection with the adjacent area of the first to-be-grabbed penicillin bottle, if not, sequentially grabbing the first to-be-grabbed penicillin bottle and the second to-be-grabbed penicillin bottle, if so, judging whether the adjacent area has an intersection as the second to-be-grabbed penicillin bottle, and judging whether the adjacent area has an intersection again until the first to-be-grabbed penicillin bottle and the second to-be-grabbed penicillin bottle are determined, wherein the adjacent area is determined by a bottle body bright band and a bottle mouth bright band.
Specifically, when grabbing, the grabbing object of the manipulator 2 is a penicillin bottle arranged at the first two positions in the moving direction of the mesh belt. In order to prevent the phenomenon that the robot 2 accidentally collides with a second penicillin bottle to be grabbed when grabbing a first penicillin bottle to cause position change, the distance between adjacent penicillin bottles needs to be considered when the recognition and positioning device selects the penicillin bottles to be grabbed, if the second penicillin bottle to be grabbed is in the vicinity of the first penicillin bottle to be grabbed, the penicillin bottles arranged at the third position are grabbed instead, if the third penicillin bottle to be grabbed is also in the vicinity, the fourth penicillin bottle to be grabbed is considered, and the like.
Because the body bright band is just a complete bottle with the combination of bottleneck bright band, consequently, can confirm the close region of waiting to snatch xiLin bottle according to body bright band and bottleneck bright band, should close on the region and can choose minimum external rectangle for use, should close on regional central point put with the central point put coincidence of body bright band and bottleneck bright band connecting wire. The length of the adjacent area can be the sum of the lengths of the bright band of the bottle body and the bright band of the bottle opening, and can also be set according to the length specification parameters of the penicillin bottle. The width of the adjacent area is set according to the width specification parameters of the penicillin bottle.
On the basis of finding all the complete penicillin bottles meeting the requirements in the grabbing area of the manipulator 2, the sequence of the penicillin bottles to be grabbed needs to be determined according to the actual movement direction of the penicillin bottles.
The method comprises the steps of firstly sequencing penicillin bottles (the penicillin bottles move from top to bottom in an actual image), wherein the sequencing reference is the line coordinate of the lower left corner point of the minimum circumscribed rectangle of the penicillin bottles, the first penicillin bottle only needs to select the penicillin bottle corresponding to the maximum value of the line coordinate, and the upper left corner of the image is set as the origin coordinate.
The second penicillin bottle needs to be selected according to the position relation between other penicillin bottles and the first penicillin bottle. Selecting a penicillin bottle with the second row coordinate size in sequence, judging whether the minimum external rectangle of the penicillin bottle is intersected with the first penicillin bottle (an intersection exists), namely whether the minimum external rectangle surrounding the two penicillin bottles has a public part, if not, the penicillin bottle is the second penicillin bottle to be grabbed, if so, continuously judging whether the penicillin bottle with the third row coordinate size in sequence is intersected with the first penicillin bottle, sequentially judging until finding the first another penicillin bottle which is not intersected with the first penicillin bottle, and grabbing the penicillin bottle as the second penicillin bottle to be grabbed.
It should be noted that, if all the remaining complete penicillin bottles are found, and no satisfactory penicillin bottle is found, only the first penicillin bottle is grabbed.
