For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0026] Please refer to the attached Figure 1 To the attached Figure 3 The present invention describes a target for high-precision measurement of a catheter frame.

[0027] like Figure 1 As shown, the target for high-precision measurement of the catheter frame in the utility model includes a black background support plate 101, a crosshair 102 is arranged on the black background support plate 101, a white ring 103 is arranged on the outside of the crosshair 102, a white ring 103 is arranged on the side of the white ring 103 away from the crosshair 102, the crosshair 102 is arranged at the center of the circle, the white ring 103 and the white ring coding belt 104 are both arranged with the crosshair 102 as the center of the circle, and the black background support plate 101 is placed on the catheter frame to accurately measure the catheter frame.

[0028] By providing a crosshair 102, a white ring 103, a white ring coding band 104, and a white arc 105 on a black base support plate 101, the influence of ambient light, weather, and other environmental conditions is reduced, enabling the dual-use of drone photogrammetry and a total station, ensuring the scientific nature of the surveying project. The front and back of this application are made of different materials. The front side uses reflective film, which has the advantages of long distance measurement, large angle measurement, and long service life. The back side uses double-sided adhesive material with adhesive properties, which allows for easy attachment to any position on the catheter rack, enabling precise measurement of the catheter rack.

[0029] Further, if Figure 1 and Figure 2 As shown, a crosshair 102 is drawn at the center of the circle, and a white ring 103 and a white ring coding band 104 are arranged at intervals along the center of the circle; a white arc 105 is arranged on the side of the white ring coding band 104 away from the white ring 103; the white arc 105 is symmetrical with the crosshair 102 as the center of the circle and is arranged at intervals on the outside of the white ring coding band 104.

[0030] In this embodiment, preferably, a crosshair 102 is drawn at the center of the circle for aiming the total station. The width of the crosshair 102 should be 0.5 mm, which can provide sufficient clarity and observation accuracy. In order to adapt to different observation conditions, the contrast between the crosshair 102 and its surrounding background is ensured to be 1:21, ensuring that the crosshair can still be clearly seen in a dimly lit environment.

[0031] The innermost ring is designed as a complete circle, and the outermost ring is designed as two non-intersecting ring belts. The two white ring arcs 105 each occupy 1 / 4 of the ring and are diagonally distributed. The short sides can be extended; the center of the circle can be positioned through the center of the circle.

[0032] Preferably, the white circular coding tape 104 adopts the binary coding principle, dividing the coding tape into 8 parts, with a total of 8 coding elements. The grayscale of each coding element can be assigned a value of 0 (black) or 1 (white). The coding tape information is read in a clockwise (or counterclockwise) direction to form an 8-bit binary number. Due to the different starting points of the code reading, there are a total of 8 binary values. Similarly, the decimal value corresponding to the smallest binary value is selected from these 8 possible values ​​as the decoding value.

[0036] In this embodiment, the reverse side is made of a double-sided adhesive material with an adhesive function, which is convenient for attachment to any position of the catheter rack, thereby achieving precise measurement of the catheter rack.

[0037] In a preferred embodiment 1, a coding mark having a size of 50 mm*50 mm is attached to the center of the catheter and is mainly used for identification in locations with space limitations. In a preferred embodiment 2, a coding mark having a size of 200 mm*200 mm can be attached to any position of the object to be measured for photogrammetry.

[0038] Based on the target of high-precision measurement of the jacket, this utility model adopts a black base support plate 101 with a crosshair 102, a white ring 103, a white ring coding band 104, and a white arc 105. This reduces the influence of ambient light, weather, and other environmental conditions, and can achieve the dual functions of drone photogrammetry and total station, ensuring the scientific nature of the measurement project. The front and back of this application are made of different materials. The front side uses reflective film, which has the advantages of long distance measurement, large angle measurement, and long service life.
