Title:
POSITION MEASURING DEVICE AND METHOD FOR FLYING OBJECT
Document Type and Number:
Japanese Patent JP3183820
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To sense the position of a flying object accurately and simply.
SOLUTION: Light L in screen form is cast from a light projecting means 1, and the reflection light generated when a flying object 2 passes this light L is taken in as an image by an image taken-in means 3. On the basis of the image obtained, the angle of the flying object direction to a specified direction is calculated by an angle calculating means. The position of the object 2 passing the screen light L is calculated by a position calculating means from the positional relation of the screen light 1 with the image taken-in position of the object 2 and the calculated angle given by the angle calculating means.
