Title:
仮想物体制御方法および仮想物体制御装置および記録媒体
Document Type and Number:
Japanese Patent JP4282112
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To control an object in a virtual space created on a computer through more realistic operation by extracting information regarding the position, movement and direction of an object to be recognized from its picked-up image and controlling the controlled object in the virtual space corresponding to the recognized object according to the information. SOLUTION: An image capture part 1 captures a distance image by using a light emission part and a light reception part. Then an image process part 4 extracts outline information from the distance image data obtained by the image capture part 1 according to the reflection coefficient and distance value of a playing tool as the recognition object. Then the gravity center position, direction, and the moving speed of the gravity center position are calculated from the extracted outline information. A virtual space control part 3 makes the gravity center position, the direction, and the moving speed of the gravity center position, extracted from the distance image, correspond to the gravity center position, the direction, and the moving speed of the gravity center position of a corresponding CG model in the virtual space. For the correspondence, the coordinates, units and sizes are so converted to match them with the inside of the virtual space.
