<p>PROBLEM TO BE SOLVED: To provide a position detection apparatus capable of highly accurately detecting a position of a moving object in a specific space while achieving cost reduction.SOLUTION: A position detection apparatus includes: first and second color information bodies 1, 3; a camera device; and a host computer 7. Each of the first and second color information bodies 1, 3 includes a main gradation image 13 and sub-gradation images 15a-15j. A rate of change of RGB values of each of the sub-gradation images 15a-15j is 10 times that of the main gradation image 13. The camera device acquires image data of the first and second color information bodies 1, 3. The host computer 7 extracts first position information RGB values by extracting first RGB values and second RGB values from the image data of the first color information body 1. Further the host computer 7 extracts second position information RGB values by extracting first RGB values and second RGB values from the image data of the second color information body 3.</p> |
