Description

[0001] The present invention relates to the technical field of image acquisition, and in particular to an information acquisition device. Background Art

[0002] Tobacco phenotypic information refers to various information presented by tobacco plants during their growth process through external morphological characteristics and internal physiological characteristics. External morphology covers plant height, stem thickness, number of leaves, leaf size, leaf shape and color, number and distribution of branches, and shape, color, number and fruit characteristics of flowers. For example, the shape of the leaves may be oblong or lanceolate, and the color is a gradient from light green to dark green. In terms of physiological characteristics, tobacco phenotypic information includes photosynthesis efficiency, chlorophyll content, water use efficiency, nutrient absorption and metabolic capacity, etc. These phenotypic information is determined by the genetic factors of tobacco itself, and is also affected by the growth environment such as light, temperature, soil fertility and moisture.

[0033] This embodiment provides an information acquisition device, which can automatically complete the cleaning process of the camera structure, eliminating the need for manual labor to waste time cleaning the camera structure, thus saving time and effort.

[0034] like Figures 1 to 6 As shown, the information collection device includes a vehicle body 100 and an image recording device 400. A mechanical arm 200 is fixedly installed at the center of the top surface of the vehicle body 100, and a three-dimensional scanner 300 is installed at the end of the mechanical arm 200 away from the vehicle body 100, and a crawler structure 700 is provided on both sides of the vehicle body 100. The mechanical arm 200, the three-dimensional scanner 300 and the crawler structure 700 are all prior art and are not described here. There are several image recording devices 400, and the image recording device 400 includes an electric telescopic rod 410 slidably installed on the edge of the top surface of the vehicle body 100, and a camera structure rotatably installed on the movable end of the electric telescopic rod 410. The fixed end of the electric telescopic rod 410 is provided with a stopper 420, and the stopper 420 extends to the outer peripheral side of the movable end. A circular cleaning sponge is installed on the inner surface of the stopper 420. When the movable end is retracted, it can drive the camera structure to be stored in the stopper 420, so that the cleaning sponge cleans and seals the camera structure.

[0035] The above-mentioned information acquisition equipment installs a circular cleaning sponge on the inner surface of the block 420. After the information acquisition is completed, when the movable end is retracted, it can drive the camera structure to be stored in the block 420, so that the circular cleaning sponge cleans and seals the outer peripheral side of the camera structure to prevent the dust on the camera structure from affecting the recognition accuracy of the image recognition process during the next use; or the movable end can be controlled to retract during the information acquisition process to automatically clean the camera structure, without the need for manual labor to spend time cleaning the camera structure, thus saving time and effort; by setting the camera structure at the movable end, the camera structure can be freely moved in the vertical direction, and the camera structure can be accurately adjusted to the required acquisition position; by setting the mechanical arm 200, the mechanical arm 200 can drive the three-dimensional scanner 300 to change position to obtain information within a larger range; by setting the crawler structure 700 on both sides of the vehicle body 100, the stability of the vehicle body 100 when moving forward is guaranteed.

[0036] Preferably, the end of the cleaning sponge away from the fixed end is provided with an inclined surface structure 431, and the inclined surface structure 431 is exposed to the stopper 420. When the camera structure contacts the cleaning sponge, the cleaning sponge can remove dust and impurities on the surface of the camera structure, and the removed impurities and dust fall to the outside along the inclined surface structure 431.

[0037] Optionally, the camera structure includes a mounting block 441 and a rotating motor 442. The outer peripheral surface of the mounting block 441 is concavely provided with a plurality of grooves 4411 for fixing the first camera 443. The rotating motor 442 is fixed in the receiving groove at the movable end, and the output end of the rotating motor 442 is connected to the mounting block 441 in a transmission manner. The receiving groove receives the rotating motor 442 therein to protect it from the influence of the external environment; the first camera 443 is received in the groove 4411 of the mounting block 441 to protect the first camera 443 from damage by the external environment; the rotating motor 442 drives the mounting block 441 to rotate, thereby expanding the image acquisition range of the first camera 443 installed therein, and improving the comprehensiveness and efficiency of image acquisition.

[0038] See also Figure 3 and Figure 4In this embodiment, the information collection device further includes an auxiliary recording device 500, which includes a shielding plate 510 and an auxiliary plate 520 connected to the shielding plate 510 in an upward and downward sliding manner. The shielding plate 510 is hinged to the side of the vehicle body 100 through a connecting shaft 530. A plurality of second cameras 540 are installed on the side of the auxiliary plate 520 close to the vehicle body 100, and a magnetic block 550 is arranged on the side of the shielding plate 510 away from the vehicle body 100. The auxiliary recording device 500 can effectively avoid image acquisition errors caused by direct sunlight or wind, and improve the clarity and accuracy of image acquisition; the shielding plate 510 drives the auxiliary plate 520 and the second camera 540 on the auxiliary plate 520 to rotate, and the auxiliary plate 520 drives the second camera 540 to move up and down, so that the second camera 540 can obtain images at different positions in all directions. The cooperation between the auxiliary plate 520 and the shielding plate 510 can realize multi-angle image acquisition, further ensuring the comprehensiveness and accuracy of the collected information. Optionally, a first electric drive device for driving the shielding plate 510 to rotate may be provided in the mounting cavity of the vehicle body 100, a mounting groove may be provided in the shielding plate 510, and a second electric drive device for pushing the auxiliary plate 520 to slide up and down may be provided in the mounting groove. Both the first electric drive device and the second electric drive device are prior art and will not be described in detail here.

[0039] Specifically, two auxiliary recording devices 500 are provided, and the two auxiliary recording devices 500 are symmetrically installed on the same side of the vehicle body 100. The shielding plate 510 and the auxiliary plate 520 are both set to an L-shaped structure. The end of the first branch plate of the shielding plate 510 is fixedly connected to the connecting shaft 530. The two auxiliary recording devices 500 rotate in the direction of approaching each other, so that the two auxiliary recording devices 500 are adsorbed to each other through the magnetic blocks 550 corresponding to the two auxiliary recording devices 500. The provision of the magnetic block 550 facilitates the fixing of the shielding plate 510 to prevent it from swinging at will in a non-working state, thereby improving the stability and safety of the device. In this embodiment, a wire 560 for connecting to the second electric drive device is provided in the auxiliary plate 520, and the second electric drive device is electrically connected to the electric control drive device provided in the installation cavity of the vehicle body 100 through the wire 560.

[0040] See also Figure 5 and Figure 6The information acquisition device also includes an image stabilizing device 600, which includes two support plates 610 respectively installed on the two side walls of the installation cavity of the vehicle body 100 for sliding up and down, a wavy metal spring 620 respectively hinged to the two support plates 610 at both ends, and a damping structure 630. There are several damping structures 630, and a damping structure 630 is provided between two adjacent protrusions of the wavy metal spring 620. There are two electric telescopic rods 410, and the two electric telescopic rods 410 correspond to the two support plates 610 one by one. The bottom end of the electric telescopic rod 410 is connected to the top surface of the support plate 610. The image stabilizing device 600 can effectively buffer the vibration of the image recording device 400 during the movement and improve the stability of image acquisition; the wavy metal spring 620 not only has high elasticity, but also can better disperse and absorb impact force and improve the buffering effect.

[0041] Furthermore, the damping structure 630 includes a damping chamber 631 and two damping blocks 632. The two ends of the damping chamber 631 are respectively slidably sealed and connected to the two damping blocks 632. The damping chamber 631 is filled with damping fluid. The ends of the two damping blocks 632 that are close to each other are both convexly provided with anti-blocking rings 6321. The anti-blocking rings 6321 are provided with a plurality of through holes 63211. The ends of the two damping blocks 632 that are far from each other are respectively fixedly connected to two adjacent protrusions of the wavy metal spring 620. The damping fluid can effectively reduce shock, thereby reducing the impact of vibration on image acquisition; by providing a plurality of through holes 63211 on the anti-blocking rings 6321, the damping blocks 632 will not be completely blocked by the damping fluid when moving, and the damping fluid will only hinder the movement of the damping blocks 632.

[0042] Optionally, the image stabilizing device 600 further includes a support rod 640, the two ends of which are respectively fixedly connected to the two side walls of the installation cavity, and the support rod 640 is inserted through the wavy metal dome 620, the damping block 632 and the damping chamber 631, and the damping block 632 is slidably and sealedly connected to the support rod 640. The support rod 640 can ensure that the wavy metal dome 620 contracts or stretches along the axial direction of the support rod 640, and the support rod 640 and the damping fluid cooperate to form a stable and effective shock absorption system.

[0043] Optionally, the damping structure 630 further includes a rubber pad 633, which is arranged on the inner chamber surface of the damping chamber 631 and between the anti-blocking rings 6321 of the two damping blocks 632. Preferably, the inner diameter of the rubber pad 633 gradually decreases from both ends to the middle. The rubber pad 633, the support rod 640 and the damping fluid cooperate to form a more effective shock absorption system, further reducing the impact of vibration on image acquisition; the inner diameter of the rubber pad 633 is the smallest in the middle, so that the inner diameter is as small as possible at the center line of the damping chamber 631, then the damping block 632 moves toward the damping chamber 631, and the greater the damping it receives.

[0044] The working principle of the information collection device in this embodiment is as follows:

[0045] When in use, the first camera 443 can be used to capture images of tobacco plants, the electric telescopic rod 410 can drive the camera structure to move in the vertical direction, and the rotating motor 442 can drive the mounting block 441 and the first camera 443 to rotate synchronously, thereby expanding the image capture range and improving image capture efficiency.

[0046] When a certain amount of dust adheres to the surface of the first camera 443, the movable end of the electric telescopic rod 410 is controlled to move downward so that the camera structure contacts the cleaning sponge during the downward movement. The cleaning sponge can clean the lens surface of the first camera 443. At the same time, the wiped impurities can be guided to the outside through the inclined structure 431 on the upper part of the cleaning sponge, so that the impurities can no longer remain on the lens surface of the first camera 443. When the device is not in use, the movement of the electric telescopic rod 410 can drive the mounting block 441 and the first camera 443 to always be located on the inside of the cleaning sponge, thereby preventing the lens of the first camera 443 from being exposed to the outside for a long time and causing dust to adhere to its lens surface, affecting the recognition accuracy during the image recognition process. At the same time, the cleaning sponge can prevent the trolley from being in a stopped state during the cleaning process, thereby saving a lot of time.

[0047] When the device moves to the side of the plant whose information is to be collected, the baffle plate 510 can be controlled to rotate. The rotated baffle plate 510 will block the other side of the plant to prevent direct sunlight from reflecting on the lens surface of the second camera 540 and affecting the image collection effect; when the wind in the external environment is strong, the plant will also sway continuously. At this time, the baffle plate 510 will block the plant by itself to reduce the swaying amplitude under the influence of wind, further improving the efficiency and accuracy of the device in collecting tobacco phenotypic information. At the same time, the auxiliary plate 520 is controlled to move in a straight line in the vertical direction, and the second camera 540 moves up and down synchronously, so that the phenotypic information of the plant can be collected from multiple angles, reducing the information error caused by unilateral collection.

[0048] When the device moves on the ground, since the ground in the tobacco planting area is not completely flat, the image recording device 400 will vibrate to a certain extent. At this time, the impact force generated by the vibration will be transmitted to the support plate 610, and the downward movement of the support plate 610 will squeeze the wavy metal spring 620, and the wavy metal spring 620 will shrink and buffer the impact force through its own elasticity. At the same time, during the deformation process of the wavy metal spring 620, it will synchronously drive the damping block 632 inside it to move. The damping block 632 During the movement, the damping liquid stored in the damping chamber 631 will be squeezed synchronously. After being squeezed, the damping liquid will produce a certain resistance to the movement of the damping block 632. The resistance will consume the energy generated by the vibration, further reduce the vibration amplitude of the image recording device 400, and thus improve the stability of image acquisition. At the same time, the setting of the rubber pad 633 will synchronously hinder the movement of the damping block 632 during the movement of the damping block 632, and form its motion damping, thereby making the image recording device 400 as a whole more stable during the process of recording images.

For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
