RingDing Model A
optical measurement and display of arrow positions upon arrival of the arrow at the target
saves all detected arrows for later analysis and evaluation
statistical analysis and graphical evaluation of the arrow position patterns
simultaneous operation for up to 4 target faces on a target
operation idependent of the main supply using USB power packs
very easy installation and calibration within a few minutes
Training support functions
all relevant parameters such as bow adjustments, sight parameters, arrow configurations etc. can be stored in the system
each single detected hit will be linked with these parameters
focussed analysis of how changes in parameters influence the arrow position patterns (such as grouping, shifts, etc.)
supports the standard bow tuning exercises such as blank shaft testing, Berger tests, etc.
all recorded training data can be shared with the coaches via the Archery Electronics cloud server
Tournament support functions
all required RingDing units can be meshed using the WiFi network into a single and centrally operated tournament system
autonomous recognition of all standard target faces according to WA and their various layouts on the target
participants can be assigned to individual target faces
automatic measurement of arrow positions and ring number valuation
possibility to overwrite valued rings by referees using mobile devices
live display of all detected arrows in real time on central displays, on the internet or, on mobile devices of spectators
all participants in the tounament can access and analyse their recorded shots later (ends, timeline, rings, groupings, etc.)
length 97 cm, width 27 cm, height: 13 cm
(not yet finalized, but will be < 5kg)
USB-C charger with 20W, or, USB-C power pack
3 special and calibrated 5 MP cameras with a fixed optical lense
embedded multiprocessor system with WLAN interface; temperature controlled active cooling
high-tech image processing software with a parallel control flow; database for persistent storage of arrow positions and other parameters; updates and upgrades via secured internet connection; remote controlled using other devices over WLAN
the measurement accuracy depends on the quality of the target faces and the accuracy of the calibration. If conditions are good, the position measurement accuracy is < 1mm
RingDing observes incoming arrows until they have a stable position. In foam, arrows stand still after about 1 s. On harder grounds such as compressed straw or wood, in will take longer. After the arrow is stable, the position is calculated in a very short time. On a foam target, the typical overall time between arrow impact and ready result is < 1.5 s.
all data transmissions are encrypted and authorized using certificates. Accessing personal data such as recorded arrows, training parameters requires strong password authentication.
chessboards printed on Makrolon® (polycarbonate) stripes for optical calibration of RingDing
wireless LAN router with a special configuration supporting the parallel operation of up to 100 RingDing systems. Automatic discovery of connected RingDing systems. Operation over distances > 100m in the open field.
operation independent of the main supply requires a USB-C power pack. Likewise, the WLAN router FunkDing can be powered by USB power packs. Archery Electronics recommends power packs with about 20.000 mAh in order to have enough capacity for a whole day.
