Abstract

[0002] In the past, due to limitations in equipment development, data on the movement of skipping stones on the water surface was limited to staff estimating the relative distance from the throwing point to the sinking point using marker lines. Furthermore, the number of splashes the stones made as they hit the water was also visually counted. In recent years, skipping stones has shown a trend towards becoming a competitive sport. To address this trend, it is necessary to introduce professional motion capture systems to collect dynamic information about the skipping stones on the water surface, facilitating real-time analysis of their trajectories.

[0017] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.
[0018] The specific embodiments of this utility model are described below with reference to the accompanying drawings.
[0019] Example 1
[0020] In this embodiment, a dynamic capture system for boulders is proposed. Figure 1 For reference and reference Figure 2 The dynamic capture system for water-skimming stones includes lidar, millimeter-wave radar, and camera modules.
[0021] In this embodiment, the area for skipping stones is an open water area with a embankment. LiDAR, millimeter-wave radar, and camera modules are arranged on the embankment, and the detection range covers the open water area.
[0022] To further explain, the lidar, millimeter-wave radar, and camera module are purchased from the market. The models can be selectively purchased based on the area of the open water and the technical requirements such as the acquisition accuracy. Of course, in this embodiment, the camera module is a conventional camera. In addition, it is best to use a high-speed camera to capture the movement data of the water-skimming stones on the water surface.
[0023] Furthermore, this embodiment also provides a host computer, which establishes data communication with the lidar, millimeter-wave radar, and camera module via network equipment such as a PoE switch and a router.
[0024] Specifically, the lidar, millimeter-wave radar, and camera module are connected to the PoE switch, the PoE switch is connected to the router, and the router is connected to the host.
[0025] In this embodiment, the host can generate corresponding motion data based on the collected data information. The motion data includes the trajectory of the boulders on the water surface, the number of water splashes caused by the boulders rubbing against the water surface, the size of the water splashes caused by the boulders rubbing against the water surface, and the distance from the point of release to the final sinking point of the boulders.
[0026] This embodiment is also equipped with a display module, which is connected to the host. The display module displays the motion data generated by the host and displays the motion data in a visual manner to help the stone thrower improve the stone throwing action based on the stone motion data.
[0027] This embodiment also includes a camera module that monitors the angle between the trajectory of the stone and the default horizontal line in the area where people throw stones.
[0028] It should be noted that the default horizontal line is a baseline perpendicular to the embankment. This helps the thrower observe the angle at which the stone leaves their hand and standardizes their throwing posture.
[0029] In this embodiment, the lidar and millimeter-wave radar are positioned diagonally opposite each other on the bank of an open waterway.
[0030] In this embodiment, the working mechanism of the lidar is to detect the target's position, velocity and other characteristics by emitting a laser beam towards the target, and to obtain relevant information about the target by comparing the received signal reflected back from the target (target echo) with the emitted signal and processing it appropriately.
[0031] In this embodiment, the working mechanism of the millimeter-wave radar is that the transmitter emits a millimeter-wave signal, which is reflected after encountering the target. The millimeter-wave signal is reflected back after encountering the target and is received by the radar receiver. By measuring and comparing the frequency, phase, amplitude and other information of the reflected signal, information such as the target's distance, speed and azimuth can be obtained.
[0032] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
