Description

Technical Field

[0001] The utility model relates to the field of three-dimensional laser scanning devices, in particular to a portable throwing type ground laser scanner target. Background Art

[0002] With its significant advantages such as non-contact, high resolution and high precision, terrestrial laser scanners have been widely used in many fields such as slope monitoring, civil engineering, mining and geological surveys. By pre-deploying ground targets, global three-dimensional coordinate information with consistent coordinate systems can be obtained, which plays a vital role in the acquisition and analysis of high-precision data.

[0003] Currently, scanning target balls are usually used for coordinate joint measurement. These target balls can provide extremely precise reference points, which makes the scanned data have high splicing accuracy. However, this method is difficult to apply in areas with soft soil slopes. The reason is that the target balls are often difficult to be stably fixed on the soft soil through manual operation, which leads to unreliable measurement results. Another way is to use marker boards or marker stakes for coordinate joint measurement. Although this method has good stability in certain specific environments, it also has shortcomings and is easily affected by terrain and environmental changes. In particular, on soft soil slopes, marker boards or marker stakes are prone to tilt or movement, which leads to a decrease in coordinate accuracy.

[0004] Therefore, how to develop a portable throwing-type ground laser scanner target with a simple structure, easy assembly, and the ability to adapt to the terrain environment of soft soil slopes, thereby ensuring that the ground laser scanner can achieve high-precision data collection, has become a technical problem that needs to be urgently solved by people in this field.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] The utility model discloses a portable throwing-type ground laser scanner target, comprising a circular plate assembly, a positioning rod seat assembly and a lifting support tip, wherein the circular plate assembly comprises a circular plate body, a first buffer shock-absorbing ring and a first cloth-based tape layer, wherein the first cloth-based tape layer is adhered to the upper surface of the circular plate body, the first buffer shock-absorbing ring is sleeved on the outer edge of the circular plate body, a plurality of lifting support tips are evenly distributed in a circular shape at the bottom of the circular plate body, the positioning rod seat assembly passes through the circular plate body and is threadedly fastened to the center position of the circular plate body.

[0008] Preferably, the positioning rod seat assembly includes a first threaded rod, a gasket and a fastening nut. The top end of the first threaded rod passes through the circular plate body and is connected to the gasket sleeve. The fastening nut is threadedly connected to the bottom end of the first threaded rod and fits tightly with the circular plate body.

[0009] Preferably, a second cloth-based tape layer is adhered to the top of the gasket.

[0010] Preferably, a cross-shaped groove is provided on the top of the first threaded rod, and the upper end of the first threaded rod is used to install a prism for laser scanner calibration.

[0011] Preferably, the lifting support tip includes a tip body, a second threaded rod and a connecting foot pad, and a plurality of the connecting foot pads are evenly distributed in a circular shape at the bottom of the circular plate body. One end of the second threaded rod is fastened to the connecting foot pad by a thread, and the tip body is slidably threadedly sleeved on the other end of the second threaded rod.

[0012] Preferably, the lifting support tip further includes a second buffer and shock-absorbing ring, and the second buffer and shock-absorbing ring is sleeved in the positioning groove of the tip body.

[0013] Compared with the prior art, the beneficial technical effects of the present invention are:

[0014] 1) Both the first and second cloth-based tape layers are designed with high-contrast black and white patterns and are attached to the upper surfaces of the circular plate body and the gasket, respectively, to facilitate identification in scanned data and improve the accuracy and efficiency of data processing;

[0015] 2) The first threaded rod is not only used to mount the prism for scanner calibration, but the cross-shaped groove design also provides a clear reference point and stable contact surface for the centering rod, making the centering process more intuitive and convenient. The surveyor only needs to gently place the bottom of the centering rod into the groove and make slight adjustments to achieve quick and accurate centering and complete the calibration work.

[0016] 3) Both the first and second buffer shock-absorbing rings are made of flexible buffer materials, which can effectively absorb the impact force generated during the throwing process, thereby protecting the entire device from damage and extending the service life of the device;

[0017] 4) The tip body adopts a conical design to ensure that the target remains stable in soft soil. In addition, the user can adjust the height and angle of the target by rotating the tip body, so that it can adapt to different terrain conditions, greatly improving the practicality and flexibility of the target.

The base is tightly fitted with the circular plate body 11 through the gasket 22, and the prism can be accurately leveled through the base. At the same time, in RTK measurement, accurate centering of the centering rod is a prerequisite for achieving high-precision measurement.
