Description

Technical Field

[0001] The invention belongs to the technical field of data sampling, and in particular relates to a sampling device for three-dimensional motion data. Background Art

[0002] Three-dimensional motion video analysis is a commonly used method in the field of sports biomechanics to obtain three-dimensional kinematic data. The three-dimensional motion analysis system can be used to record the technical movements of insects, and then present them in digital form through subsequent processing and analysis.

[0003] As for sampling of the three-dimensional motion data of insects, there is currently a device for collecting the three-dimensional motion data of insects based on a high-speed camera, as mentioned in the patent publication number "CN102865443B", which specifically uses a high-speed camera to collect the three-dimensional motion data of insects.

[0004] The bottom of the high-speed camera that collects the three-dimensional motion data of insects must be equipped with a support platform to support the high-speed camera to ensure the stability and legal use of the high-speed camera. The support platform contains several supporting parts, the number of which is the same as the number of high-speed cameras, such as Figure 1 and Figure 2 As shown, each support member includes a pair of strip members 1 22 and a pair of strip members 2 23, strip member 1 is longer than strip member 2, and here, strip member 2 23 is connected in parallel between strip members 1 22, and the section of strip member 1 22 extending vertically to strip member 2 23 constitutes a connecting member 222, and a plurality of support members are connected via the connecting member 222 to form the support platform.

[0005] Because the connecting member 222 extends vertically to a pair of opposite sides of the support member (i.e., the strip member 23), the support platform can only form a strip-shaped structure during assembly. In actual use, due to the constraints of the specific environment, the support member must be rotated an arc (usually an arc of π / 2 or π / 4) to avoid interference between the high-speed camera support arm on the support member and other devices on site. However, because the support platform can only form a strip-shaped structure, the arc of the support member cannot be changed, which is not suitable for the diversified presentation of high-speed cameras. Summary of the invention

[0006] In order to solve the defects in the prior art, the present invention provides a sampling device for three-dimensional motion data, which includes a high-speed camera for collecting three-dimensional motion data of insects; a support platform is arranged at the bottom of the high-speed camera to support the high-speed camera; the support platform of the high-speed camera is connected by a plurality of support members through a connecting body, and the two ends of each strip-shaped member 1 of the support member extend outside the strip-shaped member 1 connected thereto to form a connecting member for connecting another support member.

[0041] A control method for a sampling device of three-dimensional motion data according to the present invention comprises:

[0042] The two ends of each strip-shaped member 1 of the support member extend outside the strip-shaped member 1 connected thereto to form a connecting member for connecting another support member, thereby increasing the arrangement orientation of the support member.

[0043] like Figures 3 to 11 As shown, a three-dimensional motion data sampling device according to the present invention comprises:

[0044] High-speed cameras that collect data on the insects’ three-dimensional movements;

[0045] The support platform is disposed at the bottom of the high-speed camera to support the high-speed camera; the support platform of the high-speed camera is connected via a plurality of support members 211 through a connecting body.

[0046] In a preferred but non-limiting embodiment of the present invention, the support member 211 includes a strip-shaped member 3.

[0047] In a preferred but non-limiting embodiment of the present invention, the number of the strips 3 is several.

[0048] In a preferred but non-limiting embodiment of the present invention, when the number of strips 3 is a pair, the strips 3 are connected in sequence, and each strip 3 extends outside the strip 3 connected thereto to form a connecting member 31 for expanding the connection.

[0049] In a preferred but non-limiting embodiment of the present invention, when the number of strips 3 is a certain number, the strips 3 are sequentially connected to form a rack, and the rack contains an annular structure, such as a triangular annular structure, a rectangular annular structure, etc.

[0050] In a preferred but non-limiting embodiment of the present invention, the strips 3 are connected by welding; the two ends of each strip 3 extend outside the strip 3 connected thereto to form a connecting piece 31. The connecting piece 31 is used to connect with the connecting piece 31 of another support member 211 to form a support platform.

[0051] In a preferred but non-limiting embodiment of the present invention, an opening 32 is formed on the side wall of the strip-shaped member 3, and a connection opening 33 is formed on the head wall of the connection member 31, and the connection opening 33 is communicated with the opening 32. The opening 32 is convenient for the connection body to be inserted into the connection opening 33 and to be assembled with the connection body, so as to connect a pair of strip-shaped members 3 (i.e., a pair of supporting members).

[0052] In a preferred but non-limiting embodiment of the present invention, there are two pairs of strips 3, and the rectangular ring-shaped support member 211 formed by the two pairs of strips 3 can increase the stability of the high-speed camera placed thereon. Because the connecting member 31 extends on one side of the two pairs of strips 3, two pairs of supporting members 211 with the same structure can be connected at the two pairs of strips 3. Figures 3 to 5 As shown, this type of structure allows the support members 211 to be arranged into a strip structure in addition to the current support members, and can also be arranged into a support platform with a vertical structure, thereby increasing the arrangement orientation of the support members 211, which is suitable for the diversified presentation of high-speed cameras.

[0053] In a preferred but non-limiting embodiment of the present invention, Figures 4 to 7 As shown, in order to achieve a larger arc connection of the support member 211, the support member 211 also includes an expansion body 6, and the expansion body 6 can be detachably arranged on the strip member 1 3 to change the connection arc of another support member 211, thereby facilitating the diversified presentation of high-speed cameras.

[0054] In a preferred but non-limiting embodiment of the present invention, the expansion body 6 includes a main bar 62 and an attached bar 63 connected to the main bar 62, and the curvature between the attached bar 63 and the main bar 62 is β greater than zero; each expansion body 6 includes a pair of attached bars 63, and the pair of attached bars 63 are connected to the main bar 62 in a mirror image, and the technical effect is that the pair of support members 211 connected to the attached bar 63 can be set in a mirror image, so that the arrangement of the support members 211 is compact and reasonable;

In addition, the connection structure of the expansion body 6 and the supporting member can be diversified, such as the main bar 62 of the expansion body 6 can be connected to the head wall of the connecting member 31, and the attached bar 63 of the expansion body can be connected to the side wall of the strip-shaped member 3 of another supporting member, that is, the main bar 62 and the attached bar 63 of the expansion body can be integrated and connected with the side wall of the strip-shaped member 3 of the supporting member 211 and the connecting member 31 at will.

[0056] In a preferred but non-limiting embodiment of the present invention, a relief opening 64 is provided on the side walls of the main bar 62 and the attachment bar 63, and a third connection opening 65 is provided on one end of the main bar 62 and the head wall of the outer end of the attachment bar 63, and the third connection opening 65 is communicated with the relief opening 64.

[0058] In a preferred but non-limiting embodiment of the present invention, since each support member 211 is not small in size and is not suitable for transportation, the support member 211 can be constructed as a detachable structure, and the strip member 3 in the support member 211 includes a plurality of connecting strips 36 connected in sequence, and the plurality of connecting strips 36 are connected via a connecting body and constitute the strip member 3;

[0059] The side wall of the connecting strip 36 is provided with an opening 32, and the head wall of the connecting strip 36 is provided with a second connecting port, which is communicated with the opening 32. The opening 32 is convenient for the connecting body to be inserted into the second connecting port to connect the connecting strip 36 and form the strip-shaped member 1 3.

[0060] In a preferred but non-limiting embodiment of the present invention, in order to improve the anti-bending function and the supporting effect, the supporting member 211 further includes an additional strip 35, and the two ends of the additional strip 35 are connected to a pair of strip members 3.

[0061] In a preferred but non-limiting embodiment of the present invention, in order to improve the anti-bending function of the opening 32, a rib 34 is provided in the opening 32;

The high-speed camera support arm is connected to the support member 211 through the threaded connection between the tensioning screw and the threaded opening.

[0064] The beneficial effect of the present invention is that, compared with the prior art, the two ends of each strip-shaped member 1 of the support member of the present invention extend outside the strip-shaped member 1 connected thereto to form a connecting member for connecting another support member. Because connecting members are provided at the locations of each strip-shaped member 1, the arrangement orientation of the support members can be increased, thereby facilitating diversified presentation by high-speed cameras.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents, and any modifications or equivalent replacements that do not deviate from the spirit and scope of the present invention should be covered within the protection space of the claims of the present invention.
