Localization and velocity tracking of human via 3 IMU sensors. 2006. The study in [43] used local position tracking on ice hockey athletes across five international games to determine differences in dynamics between forwards and defenders. Our research provides fundamental insight into greyhound motion behaviours and sets the foundation for further work in this field to be explored.

The high magnitudes of velocity, acceleration and jerk posed significant technical challenges, as the greyhounds pushed the human tracking system beyond its original design limits.
Before Maximum, minimum and average jerk of greyhound running paths versus race time and race distance for 600 m distance race starts with a black plot showing the jerk as predicted from the shape of the lure rail. Tracking systems have been widely researched and have been used to monitor both animals and humans [22,23,24,25,26,27]. But accurate track models alone arent enough.

Greyhound racing track lure systemsAcoustical measurements within and adjacent to the starting boxes. However, fixed vision-based trackers are not so suitable for outdoor use. For instance, railway tracks and highway road designs utilise transition curves such as spiral easements between the straight and bend sections to optimise efficiency and minimise unwanted force profiles. As evident from the greyhound trajectory plots, the average running path of the greyhounds approached a round path throughout the races where the curvature was greater than zero for the distance of the race. It is especially intended to be compatible with low-cost hardware. This is feasible when the animals are restricted within an enclosed area. Authentically modeled tracks are identical to their real-life counterparts thanks to laser-scanning, from the cracks and pockmarks within the roads surface, to the defining camber and undulations that give each track its identity.

915 November 2018; Hayati H., Eager D., Brown T., Jusufi A. Even slight shifts in track temperature, humidity, overcast and other weather factors require expert decision-making on everything from your tire setup to braking approach. This gives us insight into their racing behaviours and allows us to pinpoint areas on the track that may be of high risk.

However, it also faces the same limitations as the previous vision-based trackers. Concrete gets rubbered-in along the established racing lines and grooves. A negative average yaw rate was observed as the greyhounds came out from the boxes for the 525 m starts between 3.0 s and 4.8 s into the race indicating the clockwise direction of greyhound heading. https://dl.acm.org/doi/10.1145/3347318.3355518.

This study also verified that the maximum jerk levels greyhounds experienced while racing were lower than the jerk levels that had been predicted with simulations and modelling for the track path. For medium length race distances (525 m and 600 m) the greyhounds speed gradually reduced until the end of a race where it was approximately 16.1 m/s. By gaining a deeper understanding of greyhound motion and behaviour we may be able to further minimise the number of injuries in greyhound racing and support healthier lives for the greyhounds. The IsoLynx system recorded the X and Y coordinates and clock time for each greyhound from the time they leave the starting boxes to the finish line. Carving out a new line requires expert precision and recognition of the current track conditions. Journal of Visual Communication and Image Representation 15, 3 (2004), 393--424.

The 1-turn and 2-turn races are generally conducted on oval-shaped tracks with a mechanical lure system that the greyhounds chase [3]. It is enjoyed by people of all ages from all around the country. This translates to approximately 50.8 m and 250 m greyhound turning radii at the bend and the straight, respectively. Hayati H., Eager D., Jusufi A., Brown T.

As evident from the greyhound trajectory plot, the average running path of the greyhounds approached a round path throughout the races where the curvature was greater than zero for the distance of the race. The greyhound heading yaw rate was found from the greyhound instantaneous speed and turning radius, where the average yaw rate of greyhound heading was calculated and indicated how quickly greyhounds were changing their direction on the track.

This study investigated the application of location tracking data in the context of finding racing greyhound path dynamics. The sun heats up concrete based on its position overhead. The results from this study show the possibility of such a systems deployment in data gathering in similar settings to greyhound racing such as thoroughbred and harness horse racing for understanding biomechanical kinematic performance. Furthermore, average curvature plots show for all race distance starts that there was a rapid decrease in the curvature while exiting the first bend at around 190 m and 265 m distances for the 525 m and 600 m starts, respectively. 2016. The results presented in the following sections can be broken down based on where they occurred at the track. From the average forward acceleration plot, it can be seen that greyhounds accelerated rapidly out of the boxes reaching a maximum forward acceleration beyond 4.0 m/s2 at approximately 2 s after the race start. The plan on the left shows the location of the three starts at 525 m, 600 m and 725 m. The plan on the right is a plan showing key dimensions with the track path curvature combs shown in blue.

A systematic review of 36 papers presented in [41] highlights the key differences between inertial tracking systems for performance monitoring in combat sports. However, the same cannot be said for the second track bends.
