DETAILED DESCRIPTION

[0047] In the related art, the camera 305 for obtaining the target image of the upper scrap steel is easily affected by the movement of the unpacking machine, resulting in blurred images. In addition, the camera 305 has a single fixed position and a fixed shooting angle, which cannot meet the subsequent intelligent quality inspection requirements.

[0048] In view of the above problems, the present invention provides a scrap steel image acquisition method, device and terminal, which can improve the quality of captured images and provide multi-angle images at the same time to meet the subsequent intelligent quality inspection requirements.

[0054] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0055] See also Figure 1 The embodiment of the present invention provides a scrap steel image acquisition method and a scrap steel image acquisition device 20, which are applied to an electronic terminal 10. The electronic terminal 10 may include a memory 110 and one or more processors 120.

[0056] The memory 110 and the processor 120 are electrically connected to each other directly or indirectly to realize data transmission or interaction. For example, these elements can be electrically connected to each other through one or more communication buses or signal lines. The electronic terminal 10 includes at least one software function module that can be stored in the memory 110 in the form of software or firmware or fixed in the operating system (OS) of the server. The processor 120 is used to execute the executable modules stored in the memory 110, such as the software function modules and computer programs included in the scrap steel image acquisition device 20.

[0057] The memory 110 may be, but is not limited to, a random access memory 110 (RAM), a read-only memory 110 (ROM), a programmable read-only memory 110 (PROM), an erasable programmable read-only memory 110 (EPROM), an electrically erasable read-only memory 110 (EEPROM), etc. The memory 110 is used to store computer program codes, which include computer instructions. When one or more processors 120 execute the computer instructions, the processors 120 execute the scrap steel image acquisition method.

[0058] The scrap steel image acquisition method and the scrap steel image acquisition device 20 provided by the present invention are described in detail below by using embodiments and in conjunction with the accompanying drawings. Figure 2 and 3 The scrap steel image acquisition method provided in this embodiment may include the following steps:

[0059] Step S110, when the scrap steel briquette is located in the working area 50, the status of the unpacking machine is obtained; a gate 30 is set outside the working area 50, and the gate 30 includes a chassis 301, an indicator light, a lifting rod 303 and at least two cameras 305; wherein the indicator light is communicatively connected with the unpacking machine, the chassis 301 and the camera 305, the chassis 301 is drivingly connected with the lifting rod 303, and at least two cameras 305 are spaced apart from each other on the lifting rod 303.

[0060] In this embodiment, it may be detected whether the scrap steel briquette is located in the working area 50 before step S110. For example, a pressure sensor may be provided in the working area 50. If the pressure sensor obtains a pressure signal, it is determined that the scrap steel briquette is located in the working area 50, and step S110 is executed.

[0061] In step S110, it should be noted that an infrared camera is arranged near the working area 50 to obtain in real time whether the unpacking machine is in operation. Optionally, there are two unpacking machines, which are arranged on opposite sides of the scrap steel briquette. In addition, based on the arrangement that at least two cameras 305 are arranged at intervals on the lifting rod 303, the cameras 305 at different positions can obtain images taken at different angles, which can meet the subsequent intelligent quality inspection requirements.

[0062] Optionally, the chassis 301 is 500 mm away from the unpacking machine, and the camera 305 is a 4-megapixel autofocus camera with dust and waterproof functions. There are two cameras, which are respectively arranged at both ends of the lifting rod 303, and the shooting range can cover the position of the scrap steel briquettes.

[0063] Step S130, determining whether the unpacking machine is in operation.

[0064] In step S130 , by judging the operating status of the unpacking machine, it can be determined whether the unpacking machine will interfere with or affect the shooting of the camera 305 .

[0065] Step S150: if the unpacking machine is in operation, the indicator light is controlled to display the first color, the lifting rod 303 is placed vertically, and the camera 305 is on standby.

[0066] In step S150, if the unpacking machine is in operation, it is considered that the unpacking machine at this time will affect the shooting of the camera 305. At this time, the control indicator light displays the first color to remind the staff to pay attention to safety at all times to avoid material collapse during the disassembly process and cause work injuries. At this time, the lifting rod 303 is placed vertically, and the camera 305 thereon is away from the scrap steel briquette. In addition, all cameras 305 are on standby and do not shoot the disassembly process of the unpacking machine.

[0067] Step S170, if the unpacking machine is in a stopped state, the control indicator light displays a second color, the lifting bar 303 is placed horizontally, and the camera 305 shoots; wherein the first color is different from the second color.

[0068] In step S170, if the unpacking machine is in a stopped state, it is considered that the unpacking machine at this time will not affect the shooting of the camera 305. At this time, the control display light is displayed in a second color different from the first color, reminding the staff to avoid activities that may affect the shooting light in the working area 50. At this time, the lifting rod 303 is placed horizontally, and the camera 305 on it is close to the scrap steel briquette. In addition, all cameras 305 shoot to obtain multi-angle and close-up images of the upper scrap steel.

[0069] It should be noted that the initial state of the lifting rod 303 is the vertical state, and it can be switched to the horizontal state by rotating 90 degrees. Moreover, the switching between the horizontal state and the vertical state is performed when the unpacking machine is stopped, and all cameras 305 are in standby state during this process.

[0070] In addition, it is also necessary to explain that the chassis 301 is connected to the lifting rod 303 through the motor arranged therein. Considering that the motor needs to be started and stopped frequently or the speed is adjusted, the working principle of the motor meets the variable frequency speed regulation principle, that is, the speed of the motor is proportional to the power supply frequency and inversely proportional to the number of motor pole pairs.

[0071] On the basis of the above, in order to facilitate the adjustment of the motor speed, the variable frequency speed regulation method adopts the speed regulation method of direct torque control motor current feedback, so as to detect and feedback the motor current in real time, thereby adjusting the switching state of the inverter and realizing accurate control of the motor torque. It is easy to understand that direct torque control has high dynamic performance and steady-state accuracy, can meet the speed regulation requirements when the lifting rod 303 is switched, and can enable the camera 305 to obtain high-definition images.

[0072] See also Figure 3 In addition, after step S170, the scrap steel image acquisition method further includes:

[0073] Step S310, obtaining the vibration frequency of the camera 305.

[0074] In step S310 , it should be noted that any camera 305 is provided with a vibration sensor, and the vibration sensor is used to measure the vibration frequency of the camera.

[0075] Step S330, determining whether the vibration frequency is greater than a preset frequency.

[0076] In step S330, since the camera is easily in vibration when shooting as the lifting rod 303 rotates to the horizontal position before shooting, it can be determined whether the camera is affected by vibration by judging the vibration frequency of the camera. It should be noted that in this application, the vibration frequency of each camera needs to be compared with a preset frequency. Optionally, the vibration frequency of the camera 305 can be selected between 1 Hz and 5 Hz to obtain a clear image.

[0077] Step S350, if the vibration frequency is greater than the preset frequency, the indicator light is controlled to display a third color and the camera 305 is in standby mode; wherein the third color is different from the first color and the second color.

[0078] In step S350, if the vibration frequency is greater than the preset frequency, it is considered that the vibration frequency of the camera 305 is too high, and the upper scrap steel image captured by the camera 305 may be abnormal. The indicator light displays a third color to remind the operator to pay attention to the screening or marking signal. Optionally, the first color mentioned above is red, the second color is green, and the third color is yellow.

[0079] In addition, if the vibration frequency is less than or equal to the preset frequency, it is considered that the vibration frequency of the camera 305 is small at this time, and the upper scrap steel image captured by the camera 305 meets the subsequent intelligent quality inspection requirements. After that, step S150 is executed to facilitate the unpacking machine to unpack the next layer of scrap steel briquettes.

[0080] Please refer again Figure 3 After step S350, the scrap steel image acquisition method further includes:

[0081] Step S510, obtaining the clarity of the upper scrap steel image.

[0082] Step S530, determining whether the clarity of the upper scrap steel image is less than a threshold.

[0083] In step S530, it should be noted that by judging whether the clarity of the upper scrap steel image is less than a threshold, it can be determined whether the camera image is blurred.

[0084] Step S550, if the clarity of the upper scrap steel image is less than the threshold, the control indicator light displays the second color, the control camera 305 is controlled to shoot the upper scrap steel image again, the corresponding upper scrap steel image clarity is obtained, and the clarity of the upper scrap steel image obtained again is compared with the threshold.

[0085] In step S550, if the clarity of the upper scrap steel image is less than the threshold, it is considered that the upper scrap steel image captured by the camera 305 is blurred and does not meet the subsequent intelligent quality inspection requirements. At this time, the indicator light switches to the second color, and the camera 305 captures again. After the upper scrap steel image is reacquired, return to step S510. Steps S510 to S550 are repeated until the clarity of the upper scrap steel image obtained by repeated acquisition is less than the threshold. Optionally, in the above cycle, the newly acquired upper scrap steel image covers the original upper scrap steel image.

[0086] In addition, if the clarity of the upper scrap steel image is greater than or equal to the threshold, it is considered that the upper scrap steel image meets the subsequent intelligent quality inspection requirements. Afterwards, step S150 is executed to facilitate the unpacking machine to unpack the next layer of scrap steel briquettes.

[0087] Please refer again Figure 2 , considering that the light intensity when the camera 305 is shooting is also an important factor affecting the clarity of the photo. The gate 30 also includes a fill light element 307, which can be set on the lower side of the lifting rod 303 or on the chassis 301. The specific position of the fill light element 307 is not limited in this application. Based on this, please refer to Figure 3 , before step S170, the method further includes:

[0088] Step S141, obtaining light intensity.

[0089] In step S141 , it should be noted that a photosensor may be provided near the working area 50 , and the photosensor is used to obtain light intensity.

[0090] Step S143, determining whether the light intensity is less than a preset intensity.

[0091] In step S143, by judging whether the light intensity is less than a preset intensity, it can be determined whether the camera 305 obtains sufficient light to capture a clear image during shooting.

[0092] Step S145: if the light intensity is less than the preset intensity, the fill light element 307 is controlled to turn on.

[0093] In step S145, if the light intensity is less than the preset intensity, such as at dusk when the light intensity is low, it is considered that the camera 305 may not be able to obtain sufficient natural light, and the captured image may be blurred. In this case, the fill light element 307 is controlled to turn on to supplement the light and improve the shooting quality.

[0094] In addition, if the light intensity is greater than or equal to the preset intensity, such as at noon when the light intensity is high, it is considered that the camera 305 can obtain sufficient natural light. In this case, step S170 can be directly executed.

[0095] like Figure 4 As shown, in the present application, there is a sequence for the control of the indicator light displaying the second color, the lifting bar 303 being placed horizontally, and the camera 305 shooting. In order to further improve the shooting quality in this process, step S170 specifically includes:

[0096] Step S171, obtaining that the unpacking machine is in a stopped state.

[0097] Step S172, controlling the indicator light to display a second color.

[0098] Step S173, control the lifting rod 303 to be horizontal.

[0099] Step S174, obtaining a horizontal image of the lifting rod 303.

[0100] In step S174 , it should be noted that a first camera is provided near the working area 50 for acquiring a horizontal image of the lifting rod 303 .

[0101] Step S175, determining whether the overlap between the horizontal image of the lifting bar 303 and the first reference image is greater than a first preset parameter.

[0102] In step S175, by determining whether the overlap between the horizontal image of the lifting rod 303 and the first reference image is greater than a first preset parameter, it can be determined whether the lifting rod 303 is in the working position preset in the first reference image when it is horizontally placed; or whether the lifting rod 303 is deformed due to the weight load of the camera or the fill light element 307 when it is horizontally placed.

[0103] Step S176: if the overlap between the horizontal image of the lifting bar 303 and the first reference image is greater than a first preset parameter, the camera 305 is controlled to shoot.

[0104] In step 176, if the overlap between the horizontal image of the lifting rod 303 and the first reference image is greater than the first preset parameter, it means that when the lifting rod 303 is horizontally placed, it is in the preset working position in the first reference image and has no obvious deformation, and the camera 305 shoots normally.

[0105] In addition, if the overlap between the horizontal image of the lifting bar 303 and the first reference image is less than or equal to the first preset parameter, it means that the lifting bar 303 is not in the preset working position in the first reference image when it is horizontally placed, or there is obvious deformation. The camera 305 cannot capture the image at the preset angle, and at this time, an alarm is issued to remind the staff to repair it.

[0106] Accordingly, if Figure 2 As shown, in order to improve the possible deformation problem, the gate 30 further includes a column 308, and the column 308 is located on the other side opposite to the chassis 301. When the lifting rod 303 is in a horizontal position, the end of the lifting rod 303 away from the chassis 301 is located on the column 308. It is easy to understand that the column 308 can provide support for the lifting rod 303 to prevent the lifting rod 303 from being suspended in the air, so as to improve the stress load concentration problem on the lifting rod 303.

[0107] Similar to the above, Figure 5 As shown, in the present application, there is a sequence of control of the indicator light displaying the first color, the lifting bar 303 being placed vertically, and the camera 305 being on standby. In order to further improve the service life of the gate 30 in this process, step S151 specifically includes:

[0108] Step S151, obtaining that the unpacking machine is in operation state.

[0109] Step S152, controlling the indicator light to display a first color.

[0110] Step S153, control the lifting rod 303 to be vertical.

[0111] Step S154, obtaining the vertical image of the lifting rod 303.

[0112] In step S154 , it should be noted that a second dome camera is provided near the working area 50 for acquiring a vertical image of the lifting rod 303 .

[0113] Step S155, determining whether the overlap between the vertical image of the lifting bar 303 and the second reference image is greater than a second preset parameter.

[0114] In step S155, by determining whether the overlap between the vertical image of the lifting rod 303 and the second reference image is greater than a second preset parameter, it can be determined whether the lifting rod 303 is in the preset working position in the second reference image when it is vertical, and whether there is a problem of incomplete reset or excessive reset.

[0115] Step S156: if the overlap between the horizontal image of the lifting bar 303 and the second reference image is greater than a second set parameter, the camera 305 is controlled to standby.

[0116] In step S156, if the overlap between the horizontal image of the lifting bar 303 and the second reference image is greater than the second preset parameter, it means that the lifting bar 303 is in the preset working position in the second reference image when it is vertically placed, and the reset is good. Therefore, the camera 305 is controlled to standby to prepare for the next shooting.

[0117] In addition, if the repetition between the horizontal image of the lifting bar 303 and the second reference image is less than or equal to the second preset parameter, it means that when the lifting bar 303 is placed vertically, it is not in the preset working position in the first reference image, and there is an over-reset or under-reset situation, which may affect the unpacking of the unpacking machine or the subsequent shooting of the camera 305. At this time, an alarm is issued to remind the staff to repair.

[0118] Accordingly, if Figure 2 As shown, in order to improve the insufficiency or excessive problems that may exist in the above-mentioned resetting process, the gate 30 also includes a floating plate 309, a guide rod 310 and an elastic member 311. Among them, the elastic member 311 is sleeved on the guide rod 310, and its two ends are respectively connected to the ground and the floating plate 309. On the basis of the above, when the lifting rod 303 is turned from vertical to horizontal, the lifting rod 303 is pressed against the floating plate 309, so that the floating plate 309 moves downward, thereby controlling the lifting speed of the lifting rod 303, and avoiding the lifting speed of the lifting rod 303 being too high and causing the lifting rod 303 to be misplaced.

[0119] See also Figure 6 The scrap steel image acquisition device 20 provided in this embodiment may include an acquisition module 210 , a judgment module 220 and a control module 230 .

[0120] The acquisition module 210 is used to acquire the status of the unpacking machine when the scrap steel briquette is located in the working area 50. Optionally, the acquisition module 210 can be used to execute step S110 in the above control method to achieve the corresponding technical effect. Accordingly, the acquisition module 210 can also execute other acquisition steps in the above control method, such as steps S141, S310, S510, etc.

[0121] The judgment module 220 is used to judge whether the unpacking machine is in operation.
