Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present application.
The method for device detection provided by the embodiment of the application can be applied to the device detection equipment shown in FIG. 1. The device inspection apparatus shown in fig. 1 includes a hopper 10, a vibration plate 11, a rail 12, a first position sensor 13, an image pickup mechanism, a turntable 19, a blanking mechanism 21, and the like. Wherein the image capturing mechanism may comprise a plurality of image capturing devices. As shown in fig. 1, the image capturing mechanism may include a first image capturing device 14, a second image capturing device 15, a third image capturing device 16, a fourth image capturing device 17, a fifth image capturing device 18, a sixth image capturing device 20, and the like. During operation of the device inspection apparatus, the devices to be inspected are unloaded by the hopper 10 onto the vibration tray 11, the vibration tray 11 conveys the devices to be inspected to the rail 12, and the devices to be inspected are placed on the turntable 19 via the rail 12. The turntable 19 rotates to drive the device to be detected to advance, and the device to be detected sequentially passes through the first sensor 13, the plurality of image acquisition devices and finally reaches the blanking mechanism 21 to be received. When the first sensor 13 on the turntable 19 detects a device to be detected, the control system of the device detection apparatus obtains the time when all the image capturing apparatuses take a picture of the device and the time when the blanking mechanism 21 performs blanking. In one example, when the blanking mechanism 21 is a blow blanking mechanism, the control system will obtain the time for each needle of the blow blanking mechanism to blow.
Taking the image acquisition device as an example, when the device to be detected is conveyed from the vibrating disk 11 to the rotating disk 19 through the rail 12, the device to be detected first passes through the initial position sensor, namely the first position sensor 13, and at this time, the detection time sequence corresponding to the device to be detected is triggered, including the time for taking pictures of the device by six cameras; after each camera shoots, the corresponding thread executes the corresponding algorithm to process the picture shot by the corresponding camera so as to determine whether the device to be detected is qualified. In a specific implementation, because different cameras shoot different angles of images, defects which are easy to appear on different surfaces of a device are different, and different algorithms can be adopted for processing the cameras in different positions. The control system can collect the processing results of the images shot by all the cameras, and obtain the final detection result (if the device to be detected belongs to a qualified product, an undetermined product or an unqualified product) according to the processing results, so as to determine the needle heads needing to blow air in the blanking mechanism 21, wherein the corresponding needle heads blow air when the device reaches the air blowing position of the device, and blow the device into the corresponding material box.
Fig. 2 schematically shows a flow diagram of a method for device inspection according to an embodiment of the present application. As shown in fig. 2, in the embodiment of the present application, there is provided a method for device inspection, applied to a device inspection apparatus, where the device inspection apparatus includes an image capturing mechanism, and the image capturing mechanism is used to capture an image of a device, where the method may include the following steps:
and S10, judging whether the processing of all the images collected by the image collecting mechanism is completely finished at the preset moment.
It should be understood that one of the common modes of device detection is visual detection, a plurality of cameras are often arranged in detection equipment for executing visual detection operation, on a path that a conveying mechanism drives a device to move, the device can pass through shooting positions of the cameras, the cameras can shoot the device from multiple directions to collect images of the device at different angles, whether each position of the device is defective or not is judged by processing the images, the device is determined to be a good product or a defective product, and then the device is discharged into a corresponding material receiving box. Therefore, it is required to ensure that images shot by all cameras for the device are processed by the image processing algorithm before the device reaches the material receiving mechanism, and if the algorithm of the image shot by one camera is not completely operated, a correct result may not be given. Generally, after each camera finishes shooting, an algorithm corresponding to the camera immediately starts to process an image shot by the camera, so that in the whole detection process, a plurality of cameras sequentially shoot images, and corresponding algorithms run in parallel, thereby improving the efficiency of image processing. However, in practical applications, the hardware and software still have difficulty getting stuck, which may result in that the device has reached the receiving position of the receiving mechanism and the image of the device is not processed, because the system sends the receiving commands in sequence, even if the image of the device is processed by the algorithm and the device has missed the receiving position, the system still sends the receiving command corresponding to the device, for example, the device a is defective as a result of detection, the receiving command is sent to receive the device a into the receiving box of defective, but another device B actually arranged behind the device a is located at the receiving position, and the device B may actually be good, but the receiving mechanism receives the receiving command to place the device at the receiving position into the receiving box, so the command actually lets the defective receiving mechanism mistakenly receive the device B into the receiving box, the device a is not received correctly, that is, the problem of instruction dislocation occurs. According to the embodiment of the application, whether all the processing of all the images acquired by the image acquisition mechanism is finished is judged at the preset moment, and under the condition that the judgment result is negative, the device is directly determined to be the to-be-determined product, so that the problem of instruction dislocation can be effectively avoided.
It should be noted that, the processing process of the image acquired by the image acquisition mechanism may be implemented locally on the device detection apparatus, or may be implemented by other apparatuses or a cloud platform, which is not limited in this embodiment of the present application.
The preset time can be determined according to the specific design of the device detection equipment, in one example, the device detection equipment further includes a blanking mechanism, the image acquisition mechanism includes a plurality of image acquisition devices, and the image acquisition mechanism is disposed at an upstream position of the blanking mechanism, and the method further includes: and determining the generation time of the processing result of the image acquired by the device by the image acquisition equipment closest to the blanking mechanism as the preset time.
Referring also to fig. 1, taking as an example that the image capturing mechanism includes six image capturing mechanisms and the image capturing apparatus closest to the blanking mechanism 21 is the sixth image capturing apparatus 20, the preset time is the generation time of the processing result of the image captured by the sixth image capturing apparatus 20.
In a specific implementation, the device detection apparatus may further include a first position sensor 13, the first position sensor 13 being located at an upstream position of the image capturing mechanism, and the method further includes: in response to a trigger instruction sent by the first position sensor 13 when the device is detected, determining the image acquisition time of each image acquisition device and the blanking time of the blanking mechanism 21 according to the running speed of the device in the device detection device, the distance between the position of the first position sensor 13 and each image acquisition device, and the distance between the position of the first position sensor 13 and the blanking mechanism 21, and respectively controlling the image acquisition device or the blanking mechanism to execute corresponding operations when the image acquisition time or the blanking time is reached.
After each image acquisition device acquires an image by executing corresponding operation, the device detection device or the cloud platform and other devices can process the acquired image to obtain a processing result, and the processing result is stored in a preset storage position. At the time of generating the processing result of the image acquired by the sixth image acquisition device 20, it may be determined whether all the processing of the images is completed by searching whether the processing results of the images acquired by the other five image acquisition devices exist in the preset storage location.
In another example, the device inspection apparatus further includes a feeding mechanism and a second position sensor, the image capturing mechanism includes a plurality of image capturing devices, and the second position sensor is disposed between the feeding mechanism and the image capturing device closest to the feeding mechanism, and the method further includes: the detection timing at which the second position sensor detects the device is determined as a preset timing.
Referring to fig. 1, taking as an example that the image capturing mechanism includes six image capturing mechanisms and the image capturing apparatus closest to the blanking mechanism 21 is the sixth image capturing apparatus 20, a second position sensor (not shown) is disposed between the blanking mechanism 21 and the sixth image capturing apparatus 20, and the preset time is the detection time of the device detected by the second position sensor.
When the device is driven by the conveying mechanism to sequentially pass through the shooting positions of all the image acquisition mechanisms and then continuously operate, the device can be detected by the second position sensor before reaching the blanking mechanism 21. At this time, it is also possible to search whether the processing results of the images captured by the respective image capturing mechanisms have been generated in their entirety by accessing the preset storage location.
And S20, in the case that the judgment result is yes, determining the detection result of the device according to the processing results of all the images.
It should be understood that, when the processing of all the images acquired by the image acquisition mechanism is completed at the preset time, it is described that the image of the device is processed by the algorithm, and the material can be received in a normal manner at this time, that is, the final detection result of the device is determined according to the processing results of the image of the device acquired by all the image acquisition mechanisms, and then the material is received according to the detection result.
And S30, determining the detection result of the device to be determined under the condition that the judgment result is negative.
And under the condition that all the images acquired by the image acquisition mechanism are not completely processed at the preset moment, the situation that the images are not completely processed by the algorithm is indicated, and the device is directly determined to be the undetermined product. Referring to fig. 1, if the processing result corresponding to the image acquired by the third image acquisition device 16 is missing, that is, the image acquired by the third image acquisition device 16 is not processed by the algorithm, at this time, the algorithm corresponding to the third image acquisition device 16 will not wait for the device to continue processing the image, but the device is directly determined to be the predetermined item.
And when the device is determined to be the object to be determined, sending a material receiving instruction, and placing the device into a material receiving box of the object to be determined. Therefore, after the receiving instruction is received by the blanking mechanism 21, the device can be placed into the material box of the to-be-detected product when the device reaches the blanking position, the problem that the receiving instruction of the device influences other devices due to the fact that the operation result of the algorithm is waited is effectively avoided, and instruction dislocation is solved.
The second position sensor is arranged between the blanking mechanism and the image acquisition equipment which is closest to the blanking mechanism, and at the moment when the device to be detected is detected by the second position sensor, the device can be determined to be a to-be-determined product as long as an algorithm corresponding to any one image acquisition equipment is not processed, so that the problem of instruction dislocation is solved more thoroughly.
The embodiment of the application judges whether the processing of all the images acquired by the image acquisition mechanism is completely finished at a preset moment; if the judgment result is yes, determining the detection result of the device according to the processing results of all the images; and determining that the detection result of the device is an undetermined product under the condition that the judgment result is negative. The image acquisition mechanism is used for acquiring images of the device to be determined, wherein whether all the images acquired by the image acquisition mechanism are processed or not is detected at a specific time, and then whether the device is classified as a to-be-determined product or not is determined, so that the problem of instruction dislocation can be effectively avoided, and the accuracy of a detection result is improved.
Fig. 3 schematically shows a flow diagram of a method for device inspection according to another embodiment of the present application. As shown in fig. 3, in the embodiment of the present application, the image capturing mechanism includes a plurality of image capturing devices, and the method may further include the steps of:
s40: and storing the processing result corresponding to the image acquired by each image acquisition device to a preset storage position.
S50: and when the preset time is reached, judging whether the storage position corresponding to each image acquisition device stores the processing result.
In an example, when the storage location corresponding to each image capturing device stores the processing result, it may be determined that all the processing of the images is completed, and the processing results corresponding to all the image capturing devices may be further extracted, and the preset storage location is emptied.
In another example, in a case that at least one processing result not stored in the storage location corresponding to each image capturing device exists, the preset storage location may be directly cleared.
In a specific implementation, when the processing result is stored, the processing results corresponding to the plurality of image capturing devices may be stored in an array, and the ordering of the storage locations corresponding to the plurality of image capturing devices in the array is consistent with the ordering of the plurality of image capturing devices in the device travel path.
According to the embodiment of the application, the processing result is stored to the preset storage position, so that the processing result can be read quickly when the preset time arrives, and the detection accuracy is improved.
