It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation. Therefore, it cannot be understood as a limitation to the present utility model
[0038] In the present utility model, unless otherwise clearly defined and limited, the terms "connection", "installation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a direct connection, or a connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances
[0039] Secondly, the "one embodiment" or "embodiment" referred to in the present utility model means specific features, structures or characteristics that can be included in at least one implementation manner of the present utility model. The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it an independent or selective embodiment that excludes other embodiments.
[0040] The following further describes in detail the specific implementation manners of the present utility model with reference to the accompanying drawings. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.
[0041] See Figure 1 and Figure 2 The present utility model provides a surveying and mapping device for an irregular spatial curved surface based on a special-shaped ruler, including a special-shaped ruler 1, a metal probe 2, a level 3, and an adjustable-height support structure 4.
[0042] This device can be used individually or in combination. When used in combination, the special-shaped rulers are connected pairwise, and the angle between two special-shaped rulers can be adjusted as needed.
[0043] Specifically, the special-shaped ruler 1 is fixed on the adjustable-height support structure 4 by bolts. The surface of the special-shaped ruler has millimeter-scale graduations, and its length can be adjusted. The special-shaped ruler is used to mark the position coordinates of the measurement points on the measured curved surface.
[0044] The side surface of the special-shaped ruler 1 is evenly distributed with probe holes 17 for installing the metal probe 2.
[0045] The metal probes 2 are equally spaced on the surface of the special-shaped ruler 1. The metal probe 2 is composed of a metal probe tip 22 and a measurement position clamp 21. Among them, the metal probe tip 22 is inserted into the probe hole 17 on the side surface of the special-shaped ruler 1, and the measurement position clamp 21 is used to fix the metal probe tip 22.
[0046] It should be noted that the diameter of the metal probe tip 22 is 0.1 mm less than that of the probe hole 17. For example, if the general probe hole is 2 mm, then the metal probe is 1.9 mm. Generally, multiple metal probes are arranged on one special-shaped ruler, the spacing between the probe holes is 5 mm, and the metal probe tips 22 can have the same length or different lengths.
[0047] The level 3 is fixed on the upper surface of the special-shaped ruler 1 for leveling the surveying and mapping device.
[0048] The adjustable-height support structure 4 is used to support the special-shaped ruler 1 and adjust the height of the special-shaped ruler 1 to be on the same plane as the measured spatial curved surface.
[0049] When the measuring device is used, a measuring plane is determined according to the measured irregular three-dimensional surface. According to the height and perimeter of the surface, several measuring devices of the present utility model are determined. According to the distance between the measuring points of the special-shaped ruler and the measured surface, metal probes 22 of different lengths are inserted into the special-shaped ruler 1, so that the metal probes contact the measuring surface, and the position is fixed with the measuring position card 21. According to the scale on the special-shaped ruler, the positions and coordinates of the discrete measuring points of the measured surface are determined. The measured curve is drawn through continuous points, and then the surface is formed according to the curves at different heights.
[0050] See Figure 3 , the special-shaped ruler 1 is a rectangular metal bar, which includes a connecting round hole 11, a connecting column 13, a bracket connecting hole 12, an outer shell ruler 14 and an inner ruler 15.
[0051] The outer shell ruler 14 and the inner ruler 15 are connected by a special-shaped ruler length adjustment fixing buckle 16. The length of the metal bar is changed by adjusting the overlapping length of the outer shell ruler 14 and the inner ruler 15, and it is fixed by the special-shaped ruler length adjustment fixing buckle 16. As Figure 2 the state one and state two in
[0052] At one end of the rectangular metal bar, there is a connecting round hole 11, and at the other end, there is a connecting column 13. The connecting column of the special-shaped ruler of one surveying and mapping device is inserted into the connecting round hole of the special-shaped ruler of another surveying and mapping device, and then tightened by a bolt 5, so that multiple devices can be connected and used jointly. The angle between the two special-shaped rulers can be adjusted according to the shape of the measured curve. For details, see Figure 4 .
[0053] A bracket connecting hole 12 is arranged in the middle of the special-shaped ruler.
[0054] See Figure 2 , in the present utility model, the adjustable height support structure 4 is a metal bracket, which is composed of a fixed base 43, an adjustable height structure 42 and a connecting component 41.
[0055] The connecting component 41 is connected and fixed to the bracket connecting hole 12 on the special-shaped ruler, so as to fix the special-shaped ruler on the adjustable height support structure 4.
[0056] Based on the surveying and mapping device provided by the present utility model, the surveying and mapping process is as follows:
[0057] (1) As Figure 5 is an irregular three-dimensional surface. In order to measure its surface, the curves at different elevations can be measured first, and then the surface is formed according to the curves at different heights.
[0058] (2) Determine a measuring plane. According to the height and perimeter of the surface, determine how many surveying and mapping devices of the present utility model are used. After the surveying and mapping devices are connected, the measured surface is surrounded therein. As Figure 6For the four surveying and mapping devices, a parallelogram outer frame is adopted. The adjustable length special-shaped ruler is adjusted to adjust the height according to the required position and ensure the levelness, so that the four surveying and mapping devices maintain the same height and the same horizontal plane, and the parallelogram frame formed is in the same plane as the measured curve.
[0059] Connect four surveying devices, one of which is an angle α. For example, if a rectangular outer frame is used, the plane angle α of the two surveying devices is 90 degrees. The coordinates of four fixed position coordinates A1, A2, A3 and A4 can be obtained based on the lengths and angles of the several surveying devices. For example, with A1 as the center point and based on the angle α between the special-shaped rulers, the four coordinates are A1 (0, 0, Z1), A2 (L2, 0, Z1), A3 (L1cosα, -L1sinα, Z1) and A4 (L2+L1cosα, L2sinα, Z1), where L1 and L2 are the lengths of two adjacent special-shaped rulers, respectively.
[0060] (3) If Figure 7 Insert metal probes of different lengths into different stylus holes (B1~Bn) of the special-shaped ruler, make the probe ends touch the measured surface, and fix the position with the measurement position card, and then determine the position of the measuring points C1~Cn on the measured surface, such as Figure 8 According to the position of C1~Cn, the measured curve is drawn through continuous points, such as Figure 9 .
[0061] Since the points on B1 to Bn are all standard positions, the coordinates of B1 to Bn can be obtained by geometric calculation based on the coordinates of A1, A2, A3 and A4 and the scale on the special-shaped ruler. Figure 7 Where B1 is the coordinate of A3 in the +X direction + M1, then the coordinate of B1 is (L1cosα+M1, -L1sinα, Z1), and M1 is the scale on the special-shaped ruler at point B1.
[0062] Obtain the length M2 of each probe, and perform geometric calculations based on the coordinates of A1, A2, A3, and A4 to obtain the coordinates of C1 to Cn. The position of C1 is the position of B1 in the +Y direction + M2, so the coordinates of C1 are (L1cosα+M1, -L1sinα+M2, Z1). Figure 10 When α is 90 degrees, the coordinates of B1 are (M1, -L1, Z1), and the coordinates of C1 are (M1, -L1 +M2, Z1), and the relative geometric calculation is relatively simple.
[0063] (4) Select curves at different elevations, draw multiple curves at different heights using the methods of steps (2) and (3), and finally form a surface by fitting the curves at different heights.
[0064] It should be noted that when the space around the object to be measured is relatively loose, the positions where the four special-shaped rulers are connected and fixed can be arranged vertically, such as Figure 10 , so that the coordinates of the subsequent measurement points can be obtained more easily. When it is not easy to arrange, the angles and lengths of several special-shaped rulers that may be used may be different, but they can all be obtained through corresponding geometric calculations.
[0065] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and deformations can still be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
