[0002] Image control points are the basis of photogrammetry control encryption and mapping. The quality of image control point target setting and the accuracy of the indicated points in the field directly affect the accuracy of the measurement results. Image control points should be able to surround the edge of the survey area to control the position accuracy within the survey area. The specific function of image control points is, on the one hand, to correct the position offset and low coordinate accuracy of the aircraft caused by limited positioning or electromagnetic interference; on the other hand, to correct other factors such as excessive high-level differences caused by the pressure needle of the aircraft.

In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0036] See also Figure 1-10 The utility model discloses a temporary image control point layout device, including a first connecting seat 1, a second connecting seat 2, a first image control point frame 3 and a second image control point frame 4, the second connecting seat 2 is rotatably connected to the first connecting seat 1; the first image control point frame 3 is detachably connected to the middle part of the first connecting seat 1, and is used to set the first image control point; the second image control point frame 4 is detachably connected to the outer side of the second connecting seat 2, and is used to set the second image control point.

[0037] In this embodiment, the first connection seat 1 is rotatably connected to the second connection seat 2, and the first image control point frame 3 is detachably connected to the middle of the first connection seat 1, and the second image control point frame 4 is detachably connected to the outer side of the second connection seat 2. During transportation, they can be completely disassembled and reasonably stored, thereby saving storage space.

[0038] Secondly, the first image control point frame 3 can be installed on the first connection seat 1 in advance, the second image control point frame 4 can be installed on the second connection seat 2, and the first image control point frame 3 can be rotated to overlap with the second image control point frame 4. When temporary image control points need to be quickly arranged outdoors, the first image control point frame 3 can be rotated to a state where it forms a certain angle with the second image control point frame 4, so that temporary image control points can be quickly arranged. This is conducive to improving the efficiency of arranging temporary image control points.

[0039] In some embodiments, a bearing 5 is further included, wherein the outer ring of the bearing 5 is connected to the first connecting seat 1 , and the inner ring of the bearing 5 is connected to the second connecting seat 2 .

[0040] In this embodiment, by providing the bearing 5, the friction between the first connecting seat 1 and the second connecting seat 2 during rotation can be effectively reduced, so that the rotation action is smoother and the labor intensity of the operator is reduced.

[0041] In some embodiments, at least two clamping holes 11 are formed on the first connection seat 1 , and a clamping piece is connected to the second connection seat 2 , and the clamping piece is connected to the clamping holes 11 .

[0042] In some embodiments, the clamping member includes a clamping rod 21, an elastic member 22 and a toggle handle 23, the clamping rod 21 is slidably connected to the inner cavity of the second connecting seat 2, and the clamping rod 21 is connected to the clamping hole 11 when extended; one end of the elastic member 22 is connected to the clamping rod 21, and the other end is abutted against the second connecting seat 2; one end of the toggle handle 23 is connected to the clamping rod 21, and the other end is arranged on the outside of the second connecting seat 2.

[0043] In this embodiment, since the first connection seat 1 and the second connection seat 2 are rotatably connected, in order to be able to rotate the first image control point frame 3 fixed on the first connection seat 1 and the second image control point frame 4 fixed on the second connection seat 2 to a preset position during subsequent use, it is necessary to pre-open a clamping hole 11 on the first connection seat 1 and correspondingly set a clamping piece on the second connection seat 2. Therefore, when the clamping piece is connected to the clamping hole 11, the first image control point frame 3 and the second image control point frame 4 can be fixed at the preset position. Thereby, the accuracy of the image control point layout is improved.

[0044] Secondly, by providing a toggle handle 23, the clamping rod 21 is toggled by the toggle handle 23, and the elastic member 22 is used to store elastic potential energy when the toggle handle 23 is pressed, and release the elastic potential energy when the toggle handle 23 is released. The clamping rod 21 can be better pressed against the clamping hole 11, preventing the first image control point frame 3 and the second image control point frame 4 from rotating by themselves after the arrangement is completed, thereby affecting the accuracy of subsequent image control point detection.

[0045] In some embodiments, the first image control point frame 3 includes a pin rod 31, a push handle 32, a first image control point plate 33 and a limit ring 34. The bottom of the pin rod 31 is in the shape of a spike for plugging into the ground; the push handle 32 is fixedly connected to the top of the pin rod 31; the first image control point plate 33 is sleeved on the pin rod 31 for setting an identifiable first image control point; the limit ring 34 is fixedly connected to the pin rod 31 and is located above the first image control point plate 33.

[0046] In this embodiment, by making the bottom of the pin rod 31 into a spike shape, the pin rod 31 can be more conveniently plugged into the ground by using the theory that the smaller the force-bearing area, the greater the pressure.

[0047] In addition, since the operator needs to press the device into the ground by hand, a push handle 32 is provided on the top of the pin rod 31, which effectively increases the force-bearing area of ​​the pin rod 31 and avoids the operator's hand pain after pressing multiple temporary image control point layout devices. To solve this problem, a rubber gasket can also be provided on the handle.

[0048] At the same time, the first image control point plate 33 is sleeved on the pin rod 31, and the first image control point plate 33 is pressed against the second connecting seat 2 by using the limit stop ring 34, so that the disassembly of the first image control point plate 33 is more convenient.

[0049] In some embodiments, a thread is provided in the middle of the pin rod 31 , and the thread is provided below the limit stop ring 34 , and the pin rod 31 is connected to the second connecting seat 2 via the thread.

[0050] In this embodiment, by providing a thread on the pin rod 31, the pin rod 31 is detachably connected to the second connecting seat 2, which can solve the problem of occupying too much space during storage.

[0051] In some embodiments, the second image control point frame 4 includes a fixed frame body 41 and a second image control point plate 42, the fixed frame body 41 is clamped with the first connecting seat 1; the second image control point plate 42 is fixedly connected to the fixed frame body 41 for setting an identifiable second image control point.

[0052] In some embodiments, a plurality of limiting slots 43 are disposed on the fixing frame 41 , and a limiting strip 12 is correspondingly disposed on the first connecting seat 1 , and the limiting strip 12 is engaged with the limiting slots 43 .

[0053] In some embodiments, the limit strip 12 is provided with a plurality of anti-slip parts, and the anti-slip parts include an anti-slip column 13 and a rebound component 14. The anti-slip column 13 is connected to the limit strip 12, and one end of the rebound component 14 is connected to the anti-slip column 13, and the other end is connected to the limit strip 12; the limit slot 43 is provided with an anti-slip groove 44, and when the anti-slip column 13 moves to the anti-slip groove 44, the anti-slip column 13 abuts against the anti-slip groove 44.

[0054] In this embodiment, since the fixing frame 41 is detachably connected to the first connection seat 1, a limit slot 43 is provided on the fixing frame 41, and a limit strip 12 is provided on the first connection seat 1 to achieve the connection between the fixing frame 41 and the first connection seat 1.

[0055] In addition, in order to ensure a more stable clamping connection between the fixed frame 41 and the first connecting seat 1, an anti-skid column 13 is arranged on the limit strip 12, the bottom of the anti-skid column 13 is in the inner cavity of the limit strip 12, and a limit component is arranged on the anti-skid column 13 to prevent the anti-skid column 13 from moving out of the limit strip 12. At the same time, a rebound member 14 is arranged at the bottom of the anti-skid column 13 to store elastic potential energy when the anti-skid column 13 is squeezed, and when the anti-skid column 13 moves to the position of the anti-skid groove 44, the rebound member 14 presses the anti-skid column 13 against the anti-skid groove 44.

[0056] Secondly, the rebound member 14 of the present application is a spring. However, it should be noted that the rebound member 14 can be made of other elastic materials, such as elastic plastics such as PC and PE materials, which are also within the protection scope of the present application.

[0057] The utility model detachably mounts the first image control point frame for setting the first image control point in the middle of the first connection seat, and detachably mounts the second image control point frame for setting the second image control point in the middle of the second connection seat, so that too much space is not occupied, which is conducive to the storage of the temporary image control point arrangement device. This overcomes the problem in the prior art that the image control point device cannot be disassembled, resulting in excessive space occupation and inconvenience in carrying.

[0058] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0059] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or suggesting their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.
