Accipitral eyeHigh speed is used to photograph in sports match what come true like the technology is auxiliary decide equipment, be called again " answer immediately put a system " , it analyses systematic He Dabing by the fast and black and white camera with 8-10 ministry higher resolution,wholesale cell phones, computer act composition. The first pace, computation of computer of have the aid of becomes the stereo space space of field measure an unit with millimeter calculative (graphic representation 1) ; The 2nd pace, use high speed to photograph the data that catchs ball flight contrail at the same time from different point of view like the head (graphic representation 2) ; The 3rd pace, pass computer computation, create these data three-dimensional image; The 4th pace, use become immediately like the technology, the athletic route that presents a ball by big screen and point of fall (graphic representation 3) . Collect a result to demonstrate from data, the time that bad news of this process place uses does not exceed 10 seconds, the error does not exceed 3 millimeter. [Advantage] the moving route that presents rubber ball well and truly and point of fall. [Defect] to field establishment asks taller, match of need break down undertakes examining. Intelligent ball - door line technologyThe company is in charge of Adidasi development,wow gold, call door line monitoring system again. Core is miniature sensor inside embedded match ball, when the ball crosses door line, sensor can transmit signal ref. This intelligence technology used magnetic field principle to give priority to control computer, offer the match to use a ball attendant the information of real time azimuth that go up, help computer transmit relevant data directly to the judgment. Adopt technology of magnetic field principle and sphere aggrandizement package, monitoring system is opposite door line to determine than what contest uses ball position precision major, efficient, can not suffer situation of movements of any such as human body, weather and appliance to disturb the interference of substandard bound element. [Advantage] can get below the condition that does not know for audience place high-tech hints, the accurate information that gets the ball crosses door line whether completely quickly. [Defect] the requirement that uses a ball to the match rises greatly,unlocked cell phones, and the assures a system very hard consistent stability below the case that suffers outside pressure ceaselessly in rubber ball.
