[0003] When using various measurement methods to measure the trajectory of the object, it is difficult to capture the trajectory of the object in space, so when positioning and installing the measurement system, it is necessary to perform multiple tests to find the trajectory of the object For a high-speed moving object, because the object’s movement time is very short, its movement trajectory is difficult to determine the position with the naked eye, which makes it difficult to find the object’s movement trajectory when installing the measurement system. position, so multiple tests are required, which causes a lot of workload, and also has a certain loss to the measuring instrument

Embodiment Construction
[0025] Embodiments of the object movement trajectory simulation frame of the present invention will be described below with reference to the accompanying drawings. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims. In addition, in this specification, the drawings are not drawn to scale, and the same reference numerals denote the same or similar parts.
[0026] Such as figure 1 As shown, in the embodiment of the object movement trajectory simulation frame of the present invention, when the object moves at a high speed through the measurement area, its trajectory is close to a straight line within a small distance (for example: the bullet shot by the rifle in the sports competition shooting event, or A baseball hit at high spe...

The invention discloses an object motion track simulation rack which comprises at least two bracket parts, and at least one simulation part adjusted and supported by the bracket parts, wherein each bracket part comprises a base, a supporting part and a transition part; the supporting part is approximately vertically arranged on the base; the transition part is adjustably arranged on the supporting part and can be subjected to rotation adjusting and positioning by taking the supporting part as an axis; the simulation part comprises a simulation rod which is arranged on the adjacent transition part on the bracket part and is used for simulating the object motion track by adjusting the supporting part and the transition part in a matched mode. According to the object motion track simulation rack, a measurement device can be mounted and debugged before actual measurement of the object motion track is performed.
Description
technical field [0001] The invention relates to a device for simulating a motion track of an object, in particular to a simulation frame for a motion track of an object. Background technique [0002] The motion trajectory is one of the most important object motion information. Through the motion trajectory, the motion law of the object can be well analyzed, and other motion information, such as speed and acceleration, can also be calculated. At present, to measure the trajectory of an object, the camera can be used to observe the object and measure the trajectory of the object (human body), which is an important analysis method in the monitoring system and sports analysis system. [0003] When using various measurement methods to measure the trajectory of the object, it is difficult to capture the trajectory of the object in space, so when positioning and installing the measurement system, it is necessary to perform multiple tests to find the trajectory of the object For a ...
