[0022] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0023] Example 1.

[0024] This embodiment provides a device for performing multi-point and multi-angle photography of wild plants. The device for performing multi-point and multi-angle photography of wild plants includes: a traction system, an image acquisition system and a control system.

[0025] The traction system is used to adjust the position of the image acquisition system. The traction system includes a plurality of traction modules, each of which includes a length adjustment component and a traction component, the length adjustment component is fixedly mounted on a fixed rod, the fixed end of the traction component is connected to the length adjustment component, and the length adjustment component is used to adjust the length of the traction component. The length adjustment components of different traction modules are fixedly mounted on fixed rods at different positions, and the wild plants are located within the range surrounded by the fixed rods at different positions.

[0026] The image acquisition system is used to photograph wild plants. The image acquisition system includes a pan-tilt and a shooting component. The pan-tilt is fixedly connected to the free end of the traction component of each traction module. The shooting component is mounted on the pan-tilt. The pan-tilt is used to adjust the shooting angle of the shooting component. The shooting component is located above the wild plants.

[0027] The control system is respectively connected to the length adjustment component, the pan / tilt head and the shooting component for communication.

[0028] The control system is used to generate multiple first control instructions according to preset shooting position points, each first control instruction corresponds to a length adjustment component, and the length adjustment component is used to adjust the length of the traction component based on the first control instruction so that the shooting component is at the preset shooting position point.

[0029] The control system is also used to generate a second control instruction according to a preset shooting angle after the shooting component is at a preset shooting position point, and the pan / tilt head is used to adjust the shooting angle of the shooting component based on the second control instruction so that the shooting angle of the shooting component is the preset shooting angle.

[0030] The control system is also used to generate a shooting instruction after the shooting angle of the shooting component is a preset shooting angle. The shooting component is used to shoot wild plants at a preset shooting position point and a preset shooting angle based on the shooting instruction to obtain a shot image.

[0031] In this embodiment, there may be three traction modules, that is, the traction system includes three traction modules, which can not only adjust the position of the image acquisition system, but also stably adjust the position of the image acquisition system due to the stability of the triangle.

[0032] In this embodiment, each traction module includes a length adjustment component and a traction component. The traction component can be a traction rope or a traction rod. The traction rope can be any flexible rope such as a zipline, a wire rope, etc. The traction rod can be any retractable rigid rod such as an electric telescopic rod. When the traction component is a traction rope, the length adjustment component can be an electric winding machine. At this time, the electric winding machine adjusts the length of the traction rope by winding; when the traction component is a traction rod, the length adjustment component can be a motor. At this time, the motor drives the traction rod to retract and retract, thereby adjusting the length of the traction rod.

[0033] The length adjustment component is fixedly mounted on a fixing rod, and the fixing rod may be a trunk of a tree growing in the wild or a rod artificially erected in the wild.

[0034] In this embodiment, the installation heights of all length adjustment components can be the same. In this case, the image acquisition system is horizontally arranged without tilting, which is conducive to the subsequent adjustment of the shooting angle of the shooting component.

[0035] The length adjustment component can change the position of the free end of each traction component by adjusting the length of the traction component, so that the pan / tilt head can be moved to different positions, thereby achieving the purpose of adjusting the position of the image acquisition system, and enabling the shooting component to shoot wild plants at different shooting positions to achieve multi-point shooting.

[0036] In this embodiment, the pan / tilt head may be an electric pan / tilt head, the shooting component may be a video camera or a still camera, and the camera may be a high-resolution camera.

[0037] The pan / tilt head can adjust the shooting angle of the shooting component so that the shooting component can shoot wild plants at different shooting angles to achieve multi-angle shooting.

[0038] In this embodiment, the traction module further includes: a first wireless control unit, the first wireless control unit is communicatively connected with the length adjustment component, and the first wireless control unit is used to receive a first control instruction and send the first control instruction to the length adjustment component.

[0039] The image acquisition system also includes: a second wireless control unit, which is respectively connected to the pan-tilt head and the shooting component for communication, and is used to receive a second control instruction and a shooting instruction, and send the second control instruction to the pan-tilt head and send the shooting instruction to the shooting component.

[0040] The first wireless control unit and the second wireless control unit can both be wireless remote control units.

[0041] The control system includes a control component and an instruction sending unit, the control component is communicatively connected with the instruction sending unit, the instruction sending unit is communicatively connected with the first wireless control unit and the second wireless control unit respectively, the control component is used to generate a first control instruction, a second control instruction and a shooting instruction, and complete the shooting position point, shooting angle and shooting control process of the shooting component, and the instruction sending unit is used to send the first control instruction to the first wireless control unit, and send the second control instruction and the shooting instruction to the second wireless control unit.

[0042] The instruction sending unit can adopt any signal transmitter.

[0043] In view of the problem that it is difficult to continuously track and monitor orchid plants at multiple points and angles for a long time, and with the advancement of software technology in recent years, the synthesis of panoramic images based on images at multiple shooting positions and angles, and the synthesis of three-dimensional models based on images at multiple shooting positions and angles through three-dimensional reconstruction technology are becoming increasingly mature. For the orchid plants being photographed and their surrounding environment, how to improve the efficiency and effect of multi-point and multi-angle shooting has become an urgent problem to be solved. Below, this embodiment takes the wild plants as orchid plants and the traction component as a zipline as an example to further explain the device for multi-point and multi-angle shooting of wild plants in this embodiment.

[0044] like Figure 1As shown, this example uses a zipline system to perform multi-point and multi-angle photography of orchid plants 2 to monitor the orchid plants 2. Specifically, the zipline system is used to automatically photograph the orchid plants 2 at multiple points and angles in the wild. By setting multiple shooting positions and shooting angles, it automatically performs overhead and side photography to obtain images with multiple shooting positions and angles. The growth area of ​​the orchid plants 2 can be fully covered, and high-quality image data can be collected for subsequent panoramic image synthesis and three-dimensional model construction. Subsequently, the panoramic images and three-dimensional models are synthesized based on all the captured images. This example proposes a method for automatically manipulating the position of the camera 5 based on the deployed zipline system to solve the problem that the orchid plants 2 cannot be photographed at multiple points and angles for a long time.

[0045] The system composition of this example includes a zipline system (i.e., a traction system), an image acquisition system, and a control system. The zipline system consists of three independent zipline modules with adjustable lengths (i.e., traction modules). Each zipline module includes an electric winding machine and a zipline with a low telescopic rate 3. The image acquisition system consists of a pan / tilt head 4 and a high-resolution camera 5.

[0046] In a typical growth area of ​​orchid plants 2, such as a mountain forest, a zipline system is set up to span a forest area of ​​several meters. A camera 5 is installed on the zipline 3 through a pan / tilt head 4. According to a preset program, it automatically shoots at any shooting position and angle in different time periods to collect the growth status of the orchid plants 2.

[0047] like Figure 2 As shown, the working principle is as follows: the electric winding machine is fixed on a tree trunk 1 above the ground or an artificially erected pole by anchoring, the free end of the zip line 3 in the three zip line modules is fixed on the upper part of the pan-tilt head 4 of the image acquisition system, and the control system uniformly sends control instructions to control the movement of the zip line 3 and the pan-tilt head 4 to realize the multi-position and multi-angle camera arrangement of the target to be photographed. After the camera 5 is moved into place, the control system sends a shooting instruction, and through the setting of multiple shooting points, multi-point and multi-angle repeatable shooting of the target to be photographed is realized.

[0048] The position control principle is: Assuming that the spatial coordinates of the anchor point (i.e., the installation location of the electric winding machine) are A(x1, y1, z1), B(x2, y2, z2), and C(x3, y3, z3), the ideal movable range of the camera 5 is the three-dimensional triangular prism formed by the triangle ABC and the ground projection of the triangle ABC. Assuming that it is necessary to move to the point P(x, y, z) in the triangular prism, it is only necessary to control the lengths of the three zip lines 3 as follows: ; ; ; In the above formula, is the length of the zipline 3 corresponding to the anchor point A; is the length of the zipline 3 corresponding to the anchor point B; is the length of the zip line 3 corresponding to the anchor point C.

[0049] Under the action of gravity, the camera 5 can move to the corresponding position. For the straight-line movement between any two points, n transition points can be linearly interpolated between the two points through the above formula, thereby achieving smooth movement.

[0050] The device of this embodiment has the following advantages.

[0051] (1) Simple layout: Only three anchor points higher than the plants to be photographed are required to fix the traction system.

[0052] (2) High operating efficiency: After the device is set up once, shooting can be completed automatically without the need for additional operations, thus reducing the cost of long-term monitoring.

[0053] (3) Environmental adaptability: Since the device has only three zip lines 3 and one camera 5 as moving parts, as long as there is a movable space of about 1 meter above the plant to be photographed, the installation requirements can be met.

[0054] Example 2.

[0055] like Figure 3 As shown, this embodiment provides a working method of a device for performing multi-point and multi-angle photographing of wild plants, which is applied to the device for performing multi-point and multi-angle photographing of wild plants described in Example 1.

[0056] S1: Generate multiple first control instructions according to a preset shooting position point, each of the first control instructions corresponds to a length adjustment component, and send the first control instructions to the corresponding length adjustment component respectively; the length adjustment component is used to adjust the length of the traction component based on the first control instruction so that the shooting component is at the preset shooting position point.

[0057] S2: After the shooting component is at a preset shooting position, a second control instruction is generated according to a preset shooting angle, and the second control instruction is sent to the gimbal; the gimbal is used to adjust the shooting angle of the shooting component based on the second control instruction so that the shooting angle of the shooting component is the preset shooting angle.

[0058] S3: After the shooting angle of the shooting component is a preset shooting angle, a shooting instruction is generated and sent to the shooting component; the shooting component is used to shoot wild plants at a preset shooting position and a preset shooting angle based on the shooting instruction to obtain a shot image.

[0059] As an optional implementation, in S1, multiple first control instructions are generated according to a preset shooting position point, specifically including: for each length adjustment component, the adjustment length corresponding to the length adjustment component is calculated according to the spatial coordinates of the installation position point of the length adjustment component and the spatial coordinates of the preset shooting position point, and the first control instruction corresponding to the length adjustment component is generated based on the adjustment length.

[0060] As another optional implementation, in S1, a plurality of first control instructions are generated according to preset shooting positions, which specifically includes the following steps.

[0061] (1) Perform linear interpolation between the current position of the shooting component and the preset shooting position to obtain several intermediate position points.

[0062] (2) For each length adjustment component, perform the following steps: For each position point, the adjustment length corresponding to the length adjustment component is calculated according to the spatial coordinates of the installation position point of the length adjustment component and the spatial coordinates of the position point, and the control instruction corresponding to the length adjustment component is generated based on the adjustment length. The position point is an intermediate position point or a preset shooting position point, and all the control instructions constitute a first control instruction corresponding to the length adjustment component.

[0063] Among them, according to the spatial coordinates of the installation position point of the length adjustment component and the spatial coordinates of the preset shooting position point, the adjustment length corresponding to the length adjustment component is calculated, which specifically includes: taking the spatial coordinates of the installation position point of the length adjustment component and the spatial coordinates of the preset shooting position point as input, and using the adjustment length calculation formula to calculate the adjustment length corresponding to the length adjustment component.

To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
