Problems solved by technology

However, there is no generally known method for accurately calibrating these, and in general there is no other way but to use inaccurate positions or positions and orientations by hand measurements as known values
Therefore, there is still room for improvement in the above method of detecting the position and orientation of an object by measuring the image coordinates of the projected image of the marker in the bird's-eye view image, because from a practical point of view, the position and orientation of the object can only be Take low-precision measurements

Embodiment Construction

[0021] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] first embodiment

[0023] The marker calibration apparatus according to the present embodiment acquires, for each marker, the position of the marker set on the imaging device with respect to the imaging device. A marker calibration device and a marker calibration method according to the present embodiment will be described below.

[0024] figure 1 is a schematic diagram showing an example configuration of the marker calibration apparatus 100 according to the first embodiment of the present invention. like figure 1 As shown, the marker calibration device 100 includes: a first-person perspective marker detection unit 110, a position and orientation calculation unit 120, a top-down perspective marker detection unit 150, an indication unit 160, a data management unit 170, and a calibration information calculation unit 180, and the marker c...

Abstract

The disclosed information processing device for a camera includes: an image acquisition device for the first image shot by the camera, an image acquisition device for the second image shot at a vertical angle, a first / second detection unit for the target coordinate information from the first / second image, and a calculation unit for regulation information from both two former units.

Description

technical field [0001] The invention relates to the calibration of markings provided on a camera device with respect to the camera's placement information. Background technique [0002] In recent years, active research activities have been conducted on mixed reality, which aims to seamlessly connect real space and virtual space. An image display device for expressing such mixed reality is realized by a video method for overlaying and drawing an image in a virtual space (drawn by a computer) on an image captured in a real space using, for example, a video camera. A drawn virtual object, characteristic information, or the like) is generated based on the position and orientation of the imaging device which will be described later. [0003] It is hoped that this image display device can be applied to various fields different from conventional virtual reality, such as surgical assistance for superimposing and displaying the state of the patient's body on the surface of the patie...
