1. A ball launch analysis device comprising:
left and right infrared sensors being provided on left and right sides of the device respectively, and being capable of detecting a left detecting zone and a right detecting zone respectively, wherein the left detecting zone and the right detecting zone are adjacent to each other and do not overlap;
left and right cameras being provided on the left and right sides of the device respectively, and being capable of capturing a left capturing zone and a right capturing zone including the left detecting zone and the right detecting zone respectively, wherein the left capturing zone and the right capturing zone overlap each other;
a placement determination control part determining whether or not a ball was placed in either a left trigger zone that is preset within the left detecting zone in the left capturing zone or a right trigger zone that is preset within the right detecting zone in the right capturing zone by using the left and right cameras;
an appearance determination control part determining whether or not an object appeared in a placement detecting zone including a placement trigger zone by using the infrared sensor corresponding to the camera of the placement trigger zone where the ball was placed when it is determined that the ball was placed in either the left trigger zone or the right trigger zone by the placement determination control part;
a disappearance determination control part determining whether or not the ball disappeared from the placement detecting zone where the object appeared by using the infrared sensor corresponding to the placement detecting zone when it is determined that the object appeared in the placement detecting zone by the appearance determination control part;
a next appearance determination control part determining whether or not the ball appeared in a launch detecting zone by using the infrared sensor corresponding to the launch detecting zone adjacent to the placement detecting zone when it is determined that the ball disappeared from the placement detecting zone by the disappearance determination control part;
a signal transmission control part transmitting a trigger signal when it is determined that the ball appeared in the launch detecting zone by the next appearance determination control part;
a capture control part capturing the ball continuously in the left capturing zone and the right capturing zone by using the left and right cameras when the trigger signal is transmitted; and
a calculation control part calculating flight parameters of the ball based on ball images of the ball continuously captured by the left and right cameras.
