Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of agricultural pest detection, and particularly relates to a crop pest detection device with multi-angle image recognition. BACKGROUND

[0002] In agricultural production, regular patrol of crop farmland is an important link for monitoring the crop pest situation. Regular pest monitoring can timely find the crop pest problems and rapidly take targeted treatment measures to avoid large-scale spread of the pests, so as to reduce the loss of crop yield. However, in traditional agricultural production, the crop pest detection is often performed by manual patrol. This method is particularly insufficient in large-scale agricultural production, because the crop planting area is wide, manual patrol not only consumes a large amount of manpower and time resources, but also is low in efficiency, and is difficult to meet the needs of modern agricultural production.

[0003] A patent with application number 202323278458.7 discloses a plant pest detection tool with adjustment function, which comprises a mounting box, a support plate, a base, a sleeve, a support rod and a detection tool body.

The plant pest detection tool with adjustment function drives the threaded rod to rotate by the driving action of the motor, so as to drive the base and the support plate to move upward, and at the same time, the detection tool body is moved upward, so that the height of the detection tool body can be adjusted.

[0004] Through the applicant's search, it is found that the above patent still has some deficiencies, for example, the above patent adjusts the angle of the camera by separating the right end of the separation bolt from the insertion rod, then unfolding the rotating rod, and rotating the rotating rod according to the required angle. This process needs manual operation, so that the device needs manual cooperation of workers during use, which reduces the practicability and efficiency of the device. CONTENT OF THE UTILITY MODEL

Rather, these embodiments are provided so that the present application will be thorough and complete, and will fully convey the scope of the present application to those skilled in the art.

[0028] It should be understood that, although the terms "first", "second", "third", etc. can be used in this application to describe various information, these information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, the first information can also be referred to as the second information, and similarly, the second information can also be referred to as the first information without departing from the scope of the application. Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise explicitly specified.

[0029] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like is based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0030] Unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting", "fixing" and the like should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0031] Referring to Figures 1-4 A crop disease and pest detection device with multi-angle image recognition, comprising:

[0032] A rack 1 is provided with a moving mechanism 2 at the bottom, which comprises a driving wheel 21, a driven wheel 22, a track 23 and a driving motor 24. Referring to Figure 4 The driving wheel 21 and the driven wheel 22 are rotatably installed on the left and right sides of the bottom of the rack 1, and the driving wheel 21 and the driven wheel 22 are connected by the track 23. The track type movement can better adapt to the rough and uneven roads in the field, and ensure the good passability of the device. A driving motor 24 for driving the driving wheel 21 to rotate is also installed on the rack 1. Two driving motors 24 can drive the left and right tracks 23 respectively, which facilitates the steering of the device and ensures its flexibility.

[0033] Further, the arrangement order of the driving wheel 21 and the driven wheel 22 on the left and right sides of the rack 1 is opposite, and the reason for such arrangement is that the driving motor 24 has a certain volume, if two driving motors 24 are installed on the front side or the rear side at the same time, then the interval between the left and right tracks 23 needs to be greater than the sum of the lengths of the two driving motors 24, so it will cause the width of the device to increase, which is not conducive to field travel; by changing the arrangement order of the driving wheel 21 and the driven wheel 22 on the left and right sides, only the interval between the left and right tracks 23 needs to be greater than the length of one driving motor 24, which can effectively shorten the width of the device and improve the passability of the device in narrow places.

[0034] Further, the front and rear sides of the rack 1 are both provided with anti-collision radars 7, and the anti-collision radars 7 and the driving motor 24 are connected with the controller, and the connection method and the control mode are both prior art in the field, which will not be repeated here. The anti-collision radar 7 can provide an anti-collision warning effect for the device, when the device is too close to the crops in the farmland and has the risk of colliding and damaging the crops, or there is an obstacle in front, a signal can be transmitted to the controller to provide early warning, and the controller can make corresponding adjustments to the steering or speed of the driving motor 24, so that the device can be timely turned to avoid crushing and damaging the crops, or prevent the device from rolling over, etc., and cause unnecessary losses.

[0035] The adjusting mechanism 6, see Figures 1-3 The mounting platform 3 is provided on the top of the rack 1, the mounting platform 3 is wrapped by the shell, and the vulnerable components such as the controller, the circuit board, the battery, etc. are installed in the mounting platform 3, the telescopic rod 4 is fixedly installed on the top of the mounting platform 3 along the vertical direction, the telescopic rod 4 is selected to be an electric telescopic rod, the camera 8 is installed on the end of the telescopic rod 4 through the adjusting mechanism 6, the shooting angle of the camera 8 can be changed through the adjusting mechanism 6, and the shooting height of the camera 8 can be changed through the telescopic rod 4, so as to realize multi-angle image acquisition, ensure the quality of the pest inspection, and avoid missing the pest problem of the crops due to the shooting dead angle.

[0036] See Figure 2 , 3, the adjusting mechanism 6 comprises a rotating disc 51, a first cantilever 61, a second cantilever 62, a third cantilever 63, a fourth cantilever 64, a base 5 is fixedly connected at the end of the telescopic rod 4, the rotating disc 51 is rotatably installed on the base 5, and a first motor 611 for controlling the rotating angle of the rotating disc 51 is fixedly installed on the base 5, and the output shaft of the first motor 611 is fixedly connected with the rotating disc 51; the first cantilever 61 is fixedly installed on the rotating disc 51, the second cantilever 62 is rotatably installed at the end of the first cantilever 61, and a second motor 621 for controlling the rotating angle of the second cantilever 62 is fixedly connected with the first cantilever 61, and the output shaft of the second motor 621 is fixedly connected with the second cantilever 62; the third cantilever 63 is rotatably connected with the other end of the second cantilever 62, and a third motor 631 for controlling the rotating angle of the third cantilever 63 is fixedly connected with the second cantilever 62, and the output shaft of the third motor 631 is fixedly connected with the third cantilever 63; the fourth cantilever 64 is rotatably installed at the end of the third cantilever 63, and a fourth motor 641 for controlling the rotating angle of the fourth cantilever 64 is fixedly connected with the third cantilever 63, and the output shaft of the fourth motor 641 is fixedly connected with the fourth cantilever 64; the fifth motor 651 is fixedly installed on the side of the fourth cantilever 64, the output shaft of the fifth motor 651 is fixedly connected with a support 65, and the camera 8 is fixedly installed on the support 65.

[0037] The first motor 611, the second motor 621, the third motor 631, the fourth motor 641 and the fifth motor 651 are all connected with the controller through a driving module, and the connection circuit and the control method are all prior art, which will not be described herein.

[0038] In use, the fifth motor 651 is controlled to realize the lifting and lowering actions of the camera 8, i.e. to adjust the angle of the pitch axis of the camera 8; the second motor 621 and the third motor 631 are controlled to realize the left and right tilting movements of the camera 8, i.e. to adjust the angle of the roll axis of the camera 8; the first motor 611 and the fourth motor 641 are controlled to realize the left and right swinging actions of the camera 8, i.e. to adjust the angle of the yaw axis. Thus, the camera 8 can be shot at multiple angles.

[0039] On the basis of the above embodiment, in work, the video image signals are first collected by the sensor built in the camera 8, and then the signals are digitally coded and compressed to form data packets for transmission through the network. The coded data packets are sent to the upper computer through the network transmission protocol. After receiving the data packets, the upper computer decodes and restores them to display the image content of the camera 8. The upper computer can send control instructions to the controller through the wireless network. After receiving the control instructions, the controller controls the motors and the camera 8 to perform corresponding actions, such as adjusting the focal length, rotating angle and moving position, to realize the shooting and sampling of the growth and pest and disease conditions of crops at all directions and angles.

[0040] Further, by setting a positioning system, real-time positioning information can be recorded during crop shooting, and the photo taken each time is bound with the positioning information at the time of shooting, so that when pest information is found, the image shooting position can be quickly found through the positioning information, and manual secondary inspection and confirmation can be quickly positioned.

[0041] Further, a communication module can be used to connect to the control module of the upper computer through a signal, the control module is connected to the man-machine interaction interface, and the user can control it; the user inputs a control instruction to the control module through the man-machine interaction interface, the control module transmits the control instruction to the communication module through a signal, the communication module further transmits the control instruction to the control chip, and the control chip can control the work of each motor and element according to the control instruction, so as to realize real-time remote control of the user.
