Abstract

PROBLEM TO BE SOLVED: To solve the problem that a person can not directly view stereoscopically the stereoscopic state of a three-dimensional space in an environment having poor visibility. SOLUTION: This device comprises a distance measuring instrument such as a millimeter wave radar capable of measuring the distance in at least one three-dimensional space, at least one instrument for detecting an object emitting characteristic energy such as an infrared camera, and a device capable of stereoscopic vision by giving to person's right and left eyes right and left images having different parallaxes computable by using distance information acquired from the three-dimensional distance measuring instrument. The subject is the device for generating the images to be presented to the right and left eyes, for displaying the distance information acquired from the three-dimensional distance measuring instrument as different parallaxes carried by each object. In addition, the three-dimensional position of the object is displayed by projecting a detection result from the device for detecting the object emitting the characteristic energy onto the right and left images.

Description

Description: BACKGROUND OF THE INVENTION [0001] This device is used in a fire site where smoke is generated, a site where visibility is poor due to water vapor such as a nuclear reactor explosion, or a gas where visibility is poor. It is used as vision for remote-controlled machines and robots operating in a three-dimensional space environment at the accident site. 2. Description of the Related Art Although a device capable of measuring a distance in a three-dimensional space with a visual field has already been realized, there is no device capable of directly viewing a three-dimensional space in stereoscopic vision when a visual field is poor. [0003] The development of a device that allows a human to directly view a three-dimensional space and the position of an object that emits characteristic energy when the visibility is poor, as stereoscopic vision. [Means for Solving the Problems] In order to solve the above-mentioned problems, a human being is used by using distance information obtained from a distance measuring device such as a millimeter-wave radar capable of measuring a distance in a three-dimensional space. It is only necessary to generate left and right image information having different parallaxes to be given to the left and right eyes, and it is sufficient to project an image of an object that emits characteristic energy onto the left and right image information. [Embodiment] A schematic diagram of the above-described invention apparatus is shown in FIG. The subject of the present invention is a parallax image creating device G. This device creates two images (I and J in FIG. 1) to be given to the left and right eyes from information of a distance image (E in FIG. 1) detected from a three-dimensional distance measuring device such as a millimeter wave radar. . The detection result E is the distance between each part of the object (A and B in FIG. 1) in the detection area and the detector. The detection result of the distance is displayed as an example as a distance image (E in FIG. 1) to be displayed by converting the detected distance into brightness. When the distance to the object is obtained, a parallax value corresponding to the distance is calculated. Next, two images (the distance image may be used as the reference image) in which the parallax value is shifted in the horizontal direction with respect to each detected object are created. When the two images are observed as a left-eye image and a right-eye image, respectively, with a stereoscopic endoscope or the like, the three-dimensional space looks three-dimensional. [Effects of the Invention] According to the present invention, stereoscopic viewing is possible even in a work environment where visibility is poor, which has been difficult in the past.
