KBO refutes controversy over ABS deviation by stadium… “Accuracy within 4.5 mm on average”
Announcement of ABS accuracy test results… “System check 4 hours before each game”
The Korea Baseball Organization (KBO) refuted the claim that the Automatic Pitching System (ABS) strike zone is different for each stadium.
On the 9th, the KBO announced the results of an ABS accuracy test conducted at 9 KBO League stadiums from the 8th to the 30th of last month.
The test was conducted by using a pitching machine to fire balls onto a memory foam board and then comparing the actual measurement coordinates with the ABS tracking coordinates. 온라인카지노
As a result, the average difference between the 9 stadiums was 4.5 mm (4.5 mm left and right, 4.4 mm up and down).
The place with the largest left-right difference was Gocheok Sky Dome in Seoul (5.8 mm), and the smallest was Hanwha Life Eagles Park in Daejeon (3 mm).
Based on the top and bottom, Seoul Jamsil Stadium (6.7 mm) had the largest difference, while Gocheok Sky Dome and Daegu Samsung Lions Park (2.5 mm) had the smallest.
The KBO said, “We agreed that confirmation through testing was necessary regarding some opinions that there were differences in the ABS judgment coordinate standards for each stadium,” and added, “As a result of this test, we confirmed that the ABS in all stadiums in the KBO League is making consistent and consistent decisions. “he said.
ABS does not track the ball’s trajectory without any error, but at least there is no significant difference between stadiums.
The KBO emphasized, “A dedicated operating staff is checking the tracking system four hours before the start of each game,” adding, “This is to ensure that the same strike zone can be operated even if the location or angle of the tracking cameras in each stadium is different.”
In addition, it was revealed that out of 55,026 pitches in a total of 185 games as of the previous day, there were only 21 cases of tracking failure.
The KBO plans to provide teams with a page where they can view ABS records within this month.
Automatic Pitching System, which the KBO League is implementing in the first team this year, is a system in which a computer determines a strike or ball when a camera installed in the baseball field records the trajectory of the pitcher’s ball.
