Description

Technical Field

[0001] The utility model relates to the field of educational robots, in particular to a visual recognition mechanism of an educational robot. Background Art

[0002] Educational robots are robots designed and applied in the field of education that combine advanced technologies from multiple fields such as artificial intelligence, computer science, and mechanical engineering. They can not only provide students with a more vivid and interesting learning experience, but also assist in the conduct of education and teaching in many aspects. The visual recognition mechanism of educational robots is a vital component of the educational robot system. It is responsible for simulating the human visual system and realizing the perception and understanding of the environment through image processing and analysis.

[0003] During the use of the existing educational robot's visual recognition mechanism, since the visual recognition mechanism of the educational robot is a prerequisite for the use of the educational robot, the visual recognition mechanism will be affected by the light and darkness of the surrounding environment and the angle of the recognized image. If the pattern is simply scanned and recognized by the camera, when the light is dark or the pattern is not aligned with the camera, it will cause fuzzy recognition. In this way, the educational robot cannot recognize and respond to the current pattern, which not only delays the normal use of the educational robot, but also reduces the scope of application of the educational robot.

[0004] Therefore, it is necessary to invent a visual recognition mechanism for an educational robot to solve the above problems. Utility Model Content

In particular, in a dark environment, the fill light can significantly improve the image quality, so that the educational robot can more accurately identify objects and environments, thereby ensuring the normal use of the educational robot and expanding the scope of application of the educational robot, so as to solve the problem that during the use of the visual recognition mechanism of the educational robot in the prior art, since the visual recognition mechanism of the educational robot is a prerequisite for the use of the educational robot, the visual recognition mechanism will be affected by the light and darkness of the surrounding environment and the angle of the recognized image, and if the pattern is simply scanned and recognized by the camera, when the light is dark or the pattern is not flush with the camera, it will cause recognition fuzziness, so that the educational robot cannot recognize the current pattern, which not only delays the normal use of the educational robot, but also reduces the scope of application of the educational robot.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a visual recognition mechanism of an educational robot, comprising a visual recognition mechanism body, which is used to carry a body for mounting a visual recognition component;

A fill light is fixedly installed inside the front recognition cavity. A fixing bolt passes through the outside of the front recognition cavity, and one end of the fixing bolt is movably connected to a photosensitive sensor.

[0008] A fine-tuning frame is arranged inside the front recognition cavity, and is used to fine-tune the camera up and down, and a rotating shaft is movably connected inside the fine-tuning frame, an image recognition camera is fixedly installed outside the rotating shaft, a movable frame is fixedly installed at the bottom of the image recognition camera, a fixed block is arranged below the image recognition camera, and a telescopic cylinder is fixedly installed above the fixed block;

A drive control module is fixedly installed inside the visual recognition mechanism body, a connecting line is fixedly connected to the outside of the drive control module, and an image recognition processing module is arranged on one side of the drive control module.

[0010] Preferably, the number of the fill-in lights is set to be multiple, and the multiple fill-in lights are distributed at equal intervals on the front identification cavity.

[0011] Preferably, the photosensor is threadedly connected to the front recognition cavity, and the image recognition camera is movably connected to the fine-tuning frame.

[0013] Preferably, a heat dissipation port is provided above the closing cover, and an adjusting fan blade is arranged inside the heat dissipation port.

[0014] Preferably, an upper insert block is fixedly installed above the closing cover, an inner slot is provided on one side of the upper insert block, and a heat dissipation filter is movably connected inside the inner slot.

[0015] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0016] The utility model is provided with a front recognition cavity, a fill light, a photosensitive sensor, a fine-tuning frame, an image recognition camera and a drive control module. When the visual recognition mechanism is used on the educational robot, after the main body angle of the visual recognition mechanism has been adjusted by the educational robot, the image recognition camera can be driven to perform up and down angle fine-tuning on the fine-tuning frame by the extension and contraction of the telescopic cylinder according to the pattern to be recognized and the angle of the image recognition camera, so that the image recognition camera can better visually recognize the pattern, and then the photosensitive sensor outside the front recognition cavity will transmit the surrounding light brightness to the drive control module through the connecting line, and the drive control module can turn on the fill light on the front recognition cavity to light up the surrounding space of the image recognition camera, so that the image recognition camera can recognize the pattern more clearly, and in this way, the brightness of the image captured by the camera can be enhanced, and the image blur and noise caused by insufficient light can be reduced, so as to improve the accuracy of visual recognition, especially in a dark environment, the fill light can significantly improve the image quality, so that the educational robot can more accurately recognize objects and environments, thus ensuring the normal use of the educational robot and expanding the scope of application of the educational robot;

[0017] The utility model is provided with a fixed card slot, a fixed card block, a closed cover, a heat dissipation port, an adjustment fan blade, an upper plug-in block, an inner slot and a heat dissipation filter. When a visual recognition mechanism is used on the educational robot, since the drive control module and the image recognition processing module need to operate at a high load when performing visual recognition, the angle of the adjustment fan blade at the heat dissipation port can be adjusted on the closed cover, so that the visual recognition mechanism can dissipate heat better and reduce the high-temperature overload situation. At the same time, during the normal heat dissipation of the closed cover, the heat dissipation filter can be inserted into the upper plug-in block, which can not only ensure the normal heat dissipation of the visual recognition mechanism, but also reduce the entry of external dust into the interior of the visual recognition mechanism, thereby ensuring the normal operation of the visual recognition mechanism.

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] The utility model provides Figure 1-5 The visual recognition mechanism of an educational robot shown includes a visual recognition mechanism body 1, which is used to carry a body for mounting a visual recognition component;

[0028] The front recognition cavity 2 is arranged outside the visual recognition mechanism body 1 and is used to protect the camera. A fill light 3 is fixedly installed inside the front recognition cavity 2. A fixing bolt 4 penetrates the outside of the front recognition cavity 2. One end of the fixing bolt 4 is movably connected to a photosensitive sensor 5.

[0029] A fine-tuning frame 6 is arranged inside the front recognition cavity 2, and is used to fine-tune the camera up and down, and the fine-tuning frame 6 is movably connected with a rotating shaft 7 inside, an image recognition camera 8 is fixedly installed outside the rotating shaft 7, a movable frame 9 is fixedly installed at the bottom of the image recognition camera 8, a fixed block 10 is arranged below the image recognition camera 8, and a telescopic cylinder 11 is fixedly installed above the fixed block 10;

[0030] An adjustment disk 12 is arranged at the bottom of the visual recognition mechanism body 1, and is used in conjunction with the adjustment structure of the educational robot. A drive control module 13 is fixedly installed inside the visual recognition mechanism body 1, and a connecting line 14 is fixedly connected to the outside of the drive control module 13. An image recognition processing module 15 is arranged on one side of the drive control module 13. The light-sensitive sensor 5 outside the front recognition cavity 2 transmits the surrounding light conditions to the drive control module 13 through the connecting line 14. The drive control module 13 can turn on the fill light 3 on the front recognition cavity 2 to illuminate the surrounding space of the image recognition camera 8, so that the image recognition camera 8 can recognize the pattern more clearly.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, the number of fill lights 3 is set to be multiple, and the multiple fill lights 3 are evenly spaced on the front recognition cavity 2. The fill lights 3 can enhance the brightness of the image captured by the camera and reduce image blur and noise caused by insufficient light. The photosensitive sensor 5 is threadedly connected to the front recognition cavity 2, and the image recognition camera 8 is movably connected to the fine-tuning frame 6. The photosensitive sensor 5 will transmit the surrounding light brightness to the drive control module 13 through the connecting line 14, thereby facilitating the adjustment of the fill lights 3.

[0032] like Figure 1 , Figure 4 and Figure 5 As shown, a fixed card slot 16 is provided above the main body 1 of the visual recognition mechanism, and a fixed card block 17 is movably connected inside the fixed card slot 16. A closed cover 18 is fixedly installed at one end of the fixed card block 17. The structure of the fixed card block 17 and the fixed card slot 16 is simple and easy to operate. If a fault occurs, the closed cover 18 can be quickly removed to repair the internal components of the main body 1 of the visual recognition mechanism. A heat dissipation port 19 is provided above the closed cover 18, and an adjustment fan blade 20 is provided inside the heat dissipation port 19. The angle of the adjustment fan blade 20 at the heat dissipation port 19 can be adjusted on the closed cover 18, so that the visual recognition mechanism can dissipate heat better and reduce the high temperature overload. An upper plug block 21 is fixedly installed above the closed cover 18, and an inner slot 22 is provided on one side of the upper plug block 21. A heat dissipation filter 23 is movably connected inside the inner slot 22. During the normal heat dissipation of the closed cover 18, the heat dissipation filter 23 is inserted into the upper plug block 21, which can not only ensure the normal heat dissipation of the visual recognition mechanism, but also reduce the entry of external dust into the interior of the visual recognition mechanism, thereby ensuring the normal operation of the visual recognition mechanism.

[0033] The practical working principle of the present invention is as follows: first, the visual recognition mechanism is docked and installed with the educational robot, and then the external power supply is turned on after the installation is completed. Then, before use, since the driving control module 13 and the image recognition processing module 15 need to operate at high load during visual recognition, the angle of the fan blade 20 at the heat dissipation port 19 can be adjusted on the closed cover 18, so that the visual recognition mechanism can dissipate heat better and reduce the high temperature overload. Then, during the normal heat dissipation of the closed cover 18, the heat dissipation filter 23 can be inserted into the upper plug-in block 21. This can not only ensure the normal heat dissipation of the visual recognition mechanism, but also reduce the external dust from entering the visual recognition mechanism, thereby ensuring the normal operation of the visual recognition mechanism. After the preparation work is completed, the educational robot can be started to perform visual recognition. When the educational robot performs visual recognition, first let the educational robot drive the adjustment disk 12 to adjust the angle position of the visual recognition mechanism body 1, and then the switch of the telescopic cylinder 11 can be turned on according to the pattern to be recognized and the angle of the image recognition camera 8. The extension and retraction of the telescopic cylinder 11 drives the image recognition camera 8 to perform fine adjustment of the up and down angles on the fine-tuning frame 6, so that the image recognition camera 8 can better visually recognize the pattern. Then the light sensor 5 outside the front recognition cavity 2 will transmit the surrounding light brightness to the drive control module 13 through the connecting line 14. The drive control module 13 can turn on the fill light 3 on the front recognition cavity 2 to illuminate the space around the image recognition camera 8, so that the image recognition camera 8 can recognize the pattern more clearly. This can enhance the brightness of the image captured by the camera and reduce image blur and noise caused by insufficient light, thereby improving the accuracy of visual recognition. At this time, the educational robot can proceed to the next step after completing the visual recognition work. Finally, after completing the installation and use of the visual recognition mechanism of the entire educational robot according to the above operations, turn off the switch of the fill light 3, turn off the switch of the telescopic cylinder 11, and cut off the external power supply if it is not used for a long time. In this way, the use process of the visual recognition mechanism of the educational robot is completed.

[0034] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
