[0055] refer to figure 1 , an overview of a calibration system to which the technology of the present disclosure is applied will be described.
[0056] figure 1 A configuration example of the calibration system of the present disclosure is shown. figure 1 The illustrated calibration system 11 is a system composed of a head-mounted display (HMD) 31, an information processor 32, and a display device 33 including a display, wherein camera parameters of a camera 31a provided in the HMD 31 are estimated by calibration (Measurement).
[0057] figure 1 The calibration system 11 is used, for example, in normal operation as a device for displaying content, such as a gaming machine. More specifically, the information processor 32 outputs content including a virtual reality (VR) image or an augmented reality (AR) image to the HMD 31 worn by the user 21 for display.

Abstract
The present disclosure relates to a head mount display and a control method of the head mount display, an information processing device, a display device, and a program that enable estimation of camera parameters of a camera mounted in an HMD without making a user mounted with the HMD aware. At a timing when the HMD is displaying contents constituted by VR images and AR images, the camera mountedin the HMD images calibration patterns displayed on an outside display, executes calibration on the basis of the images of the imaged calibration patterns, and estimates the camera parameters. At thistime, the calibration patterns displayed on the outside display are displayed in a size according to a positional relation between the HMD and the outside display. The present disclosure is applicable to an HMD.
Description
technical field [0001] The present disclosure relates to a head-mounted display, a control method of the head-mounted display, an information processor, a display device, and a program, and relates to making it possible to perform calibration without the user's knowledge and to properly make it possible, especially in a home environment, to A head-mounted display for estimating camera parameters, a control method for the head-mounted display, an information processor, a display device, and a program. Background technique [0002] In a setup including an imaging device, distortion of the optical system, deviation in the imaging direction, etc. occurs, and parameters for dealing with the distortion and deviation are measured (estimated) in advance, so that an appropriate image can be obtained by applying the parameters of the captured image . [0003] In this setting, existing parameter estimation methods usually assume only one initial measurement. Here, a known pattern on ...
