Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of surveying and mapping, in particular to a prism and target integrated measuring reflection device. Background Art
[0002] In the field of surveying and mapping technology, total stations and laser scanners are often used in combination. First, coordinate measurement is performed using a total station and a reflective prism, and then a laser scanner is used to scan the target to collect point cloud data. At the same time, the measured three-dimensional coordinates are attached to the target for point cloud data processing. However, since the measurements of the total station and the laser scanner cannot be performed at the same time, it is usually necessary to replace the reflective device at the point to be measured, which increases the complexity of the measurement work. At present, some devices have combined prisms and targets together, but these devices have failed to achieve the centering of the prism and the target, resulting in poor applicability and cumbersome operation and calculation.

During use, the prism and the target can be switched for use only by rotating the target plate, thereby significantly improving the measurement efficiency and accuracy.

[0006] The base is provided with a horizontally extending blind hole, a horizontally extending connecting pin is fixed in the blind hole, and the outer end of the connecting pin extends out of the blind hole.
[0007] The rotating pin is a T-shaped pin, one end of the rotating pin with a large diameter is fixedly connected to the target plate, the horizontal height of the two rotating pin axes is consistent with the horizontal height of the center of the target plate, and the small diameter part of the rotating pin is inserted into the positioning hole of the U-shaped frame.
[0008] The target centering pattern includes four areas divided by two diagonal lines intersecting at 90 degrees, two opposite areas are filled with white patterns, and the other two opposite areas are filled with black patterns.
[0009] A circle of fluorescent indicator stickers is arranged on the reverse side of the target plate and in the area located on the periphery of the prism positioning seat. The circle of fluorescent indicator stickers includes a plurality of fluorescent indicator stickers evenly distributed along the circumference of the target plate and in the form of isosceles triangles, and the vertex angle of each fluorescent indicator sticker points to the center of the prism.

[0011] Advantages of the utility model:
[0012] (1) The utility model directly mounts the prism on the reverse side of the target plate, and the center of the prism overlaps with the center point of the target centering pattern of the target plate, so there is no need to use a complex algorithm to calculate the deviation of the prism coordinates relative to the target coordinates, thereby reducing the error caused by calculating the center coordinate position and improving the operation accuracy;
