First Claim
1. An estimation system comprising:
- a fitting harness which a user wears and in which the user watches a video image;
an estimation device which estimates a position and a posture of the fitting harness within a predetermined space; and
an image capturing unit which captures an image of the predetermined space,wherein the fitting harness includesa plurality of marks which are provided on an external surface,a detection unit which sequentially detects posture information indicating the posture of the fitting harness, anda first transmission unit which sequentially transmits the posture information to the estimation device, andwherein the estimation device includesa storage unit which stores preset posture data of a case in which the fitting harness is present in each of a plurality of regions different from each other included in the predetermined space, for each of the regions,a first reception unit which receives the posture information,a second reception unit which receives a captured image from the image capturing unit, andan estimation unit which estimates a region having a possibility that the fitting harness is present among the plurality of regions using the captured image and the preset posture data, and estimates the region by narrowing the preset posture data to be used for a second captured image from the position and the posture in a first captured image based on posture information received after the first captured image is received, when the position and the posture of the fitting harness are estimated based on the second captured image following the first captured image among the sequentially transmitted captured images.

Abstract
To specify a position and a direction of a target having marks within a predetermined space from captured image.
There is provided an estimation system for estimating a position and a posture of a fitting harness, which includes a plurality of marks, which a user wears, and in which the user watches a video image, within a predetermined space. The estimation system stores preset posture data of a case in which the fitting harness is present in each of a plurality of regions different from each other included in the predetermined space, for each of the regions; receives a captured image of the predetermined space in which the fitting harness is included; receives posture information indicating the posture of the fitting harness from the fitting harness; and estimates a region having a possibility that the fitting harness is present among the plurality of regions using the captured image and the preset posture data, and estimates the region by narrowing the preset posture data to be used for a second captured image from the position and the posture in a first captured image based on posture information received after the first captured image is received, when the position and the posture of the fitting harness are estimated based on the second captured image following the first captured image among the sequentially transmitted captured images.

9. An estimation method of estimating a position and a posture of a fitting harness, which includes a plurality of marks, which a user wears, and in which the user watches a video image, within a predetermined space, the estimation method comprising:
-
a storing step of storing preset posture data of a case in which the fitting harness is present in each of a plurality of regions different from each other included in the predetermined space, for each of the regions; a first receiving step of receiving a captured image of the predetermined space in which the fitting harness is included; a second receiving step of receiving posture information indicating the posture of the fitting harness from the fitting harness; and an estimating step of estimating a region having a possibility that the fitting harness is present among the plurality of regions using the captured image and the preset posture data, and estimating the region by narrowing the preset posture data to be used for a second captured image from the position and the posture in a first captured image based on posture information received after the first captured image is received, when the position and the posture of the fitting harness are estimated based on the second captured image following the first captured image among the sequentially transmitted captured images.

10. An estimation program for causing a computer to estimate a position and a posture of a fitting harness, which includes a plurality of marks, which a user wears, and in which the user watches a video image, within a predetermined space, the estimation program realizing:
-
a storing function of storing preset posture data of a case in which the fitting harness is present in each of a plurality of regions different from each other included in the predetermined space, for each of the regions; a first receiving function of receiving a captured image of the predetermined space in which the fitting harness is included; a second receiving function of receiving posture information indicating the posture of the fitting harness from the fitting harness; and an estimating function of estimating a region having a possibility that the fitting harness is present among the plurality of regions using the captured image and the preset posture data, and estimating the region by narrowing the preset posture data to be used for a second captured image from the position and the posture in a first captured image based on posture information received after the first captured image is received, when the position and the posture of the fitting harness are estimated based on the second captured image following the first captured image among the sequentially transmitted captured images.
