Description

Technical Field

[0001] Embodiments of the present invention relate to information devices, and more specifically, to information devices that simultaneously acquire information about input or output regions of interest along multiple optical axes. Background Technology

[0002] Technologies are being developed for acquiring three-dimensional (3D) images using imaging devices. To acquire 3D images, depth information (depth maps) is required. Depth information represents distance in space and shows perspective information of one point relative to another in a two-dimensional (2D) image. Recently, there has been a growing trend in mobile devices and vehicles to use depth information for augmented reality (AR) content or for the main control of autonomous vehicles through the application of 3D depth-sensing cameras. Specifically, in AR / virtual reality (VR) or autonomous mobility, technologies using multiple cameras or increasing the field of view are being developed to acquire a wide range of regions of interest.

[0003] Typically, devices such as camera units used to acquire images or videos of regions of interest consist of a combination of optical transmission lenses (relay optics) aligned along the same optical axis and a sensor. Devices composed of such combinations can only acquire information about the angle of view of light incident along the same optical axis. When optical elements such as fisheye lenses are used to acquire information about a wider region of interest, the quality of the acquired information is degraded due to distortions in the acquired image. In depth information devices, sensors used in robots and autonomous vehicles need to acquire information not only about the front but also about the left and right sides. This requires the installation of multiple devices, necessitating significant space requirements and increasing unit costs. Summary of the Invention

[0103] Light source 600 can emit light signals of different wavelengths. Multiple light sources 600 can be arranged adjacent to sensor unit 300 to emit light signals. Light source 600 can emit light signals, thereby causing the light signals to reach transmission / reflection unit 200. Light source 600 can emit light signals along a first direction. Light source 600 can emit light signals toward transmission / reflection unit 200, thereby causing transmission / reflection unit 200 to transmit or reflect the light signals, thus emitting light signals along the first direction to a third direction. Light signals can be emitted in the opposite direction to the first direction to a third direction from which the external light signals are incident. Light signals emitted by light source 600 can be reflected by objects within the viewing angle of the first direction to a third direction. Light signals reflected by objects can be re-intruded onto the information device and reach sensor unit 300 through transmission / reflection unit 200.

The multiple light sources 600 can be arranged parallel to the sensor unit 300 and positioned at the same distance from the transmission / reflection unit 200 as the sensor unit 300, to emit light signals onto the first surface to the third surface 210, 220, and 230 of the transmission / reflection unit 200.

In this case, the light signals emitted by the light sources 600 can be emitted directly outward without being transmitted or reflected by the transmission / reflection unit 200. The multiple light sources 600 may include three light sources 600. The three light sources 600 can be arranged at a certain distance from the first to third surfaces 210, 220, and 230 of the transmission / reflection unit 200. When the multiple light sources 600 directly emit light signals along the first to third incident light signals, the multiple light sources 600 may not be arranged adjacent to the sensor unit 300 or parallel to the sensor unit 300.
