The present disclosure provides a system and method for a vehicle radar inspection. A system for inspecting an assembled state of a radar sensor mounted in a vehicle may include a center portion configured to align the vehicle to a reference inspection position; a mobile terminal configured to connect with an external source of communication; a scan portion configured to photograph the radar sensor at a plurality of scan positions using a terahertz wave; and a server configured to match a plurality of scan images photographed by the scan portion, to detect a three-dimensional coordinate of the radar sensor, to transmit a sensor correction value through the mobile terminal, wherein the sensor correction value is determined based on an assembly tolerance that compares with a design plan of the vehicle, and to correct a sensor angle value of the radar sensor.

The invention relates to a method for determining the quality of an imaging plate, comprising the steps of carrying out an exposure of the imaging plate, carrying out a scan of the imaging plate in order to determine an image, determining a signal-to-noise ratio of the image or/and carrying out edge recognition on the image and calculating a quality value of the imaging plate on the basis of the signal-to-noise ratio of the image or/and on the basis of the recognized edge structure. Furthermore, the invention relates to an imaging plate scanner for carrying out such a method.

Scenes can be imaged under low-light conditions using flash photography. However, the flash can be irritating to individuals being photographed, especially when those individuals' eyes have adapted to the dark. Additionally, portions of images generated using a flash can appear washed-out or otherwise negatively affected by the flash. These issues can be addressed by using a flash at an invisible wavelength, e.g., an infrared and/or ultraviolet flash. At the same time a scene is being imaged, at the invisible wavelength of the invisible flash, the scene can also be imaged at visible wavelengths. This can include simultaneously using both a standard RGB camera and a modified visible-plus-invisible-wavelengths camera (e.g., an IR-G-UV camera). The visible and invisible image data can then be combined to generate an improved visible-light image of the scene, e.g., that approximates a visible light image of the scene, had the scene been illuminated during daytime light conditions.

The present technology relates to an imaging apparatus, an imaging method, and a program capable of obtaining a color image even in a case where photographing is performed in a dark place. The apparatus includes: an infrared light emission unit that emits infrared light; a sensor array in which a plurality of pixels is arranged, the plurality of pixels including a first pixel that includes a period during which the infrared light is emitted by the infrared light emission unit as an exposure duration, a second pixel that does not include a period during which the infrared light is emitted as the exposure duration, and an infrared light pixel that receives infrared light contained in ambient light; an acquisition unit that obtains an infrared light image captured by the first pixel, a visible image captured by the second pixel, and an ambient infrared light image captured by the infrared light pixel; and an image generation unit that generates an image as a result of removing the infrared light contained in the ambient light from the infrared light image and the visible image using the ambient infrared light image. The present technology is applicable to a surveillance camera, for example.

Methods and systems for single beam scanning capable of imaging the surface of a spherical body of arbitrary radius of curvature are provided. The spherical imaging methods and systems utilize one or more off-axis parabolic (OAP) mirror to perform a geometrical transformation of the spherical surface to a flat rectilinear imaging coordinate grid such that the single scanning beam maintains a normal incidence across the curved field of view of the spherical body. The imaging methods and systems project the spherical surface to a Cartesian plane and then the remapped surface is rapidly imaged by raster-scanning an illumination beam in the rectangular coordinate such that the OAP mirror produces a rectilinear image of the target. The imaging of the spherical surface is accomplished while maintaining the target, illumination source, and detector in a stationary position. The imaging systems and methods may utilize a single source and a single detector, and may incorporate a THz illumination source. The beam scanning imaging systems and methods may be applied to corneal tissue imaging.

Disclosed herein is system for providing simultaneous machine vision illumination control and human vision illumination control. The system includes a first illumination control output that is configured to provide first illumination timing information for a first illumination source. The system also includes a second illumination control output configured to provide second illumination timing information for a second illumination source. The first illumination source is configured to provide a first frequency band of illumination for machine vision. The second illumination source is configured to provide a second frequency band of illumination for human vision. The first and second frequency bands are mutually exclusive. A related system is also disclosed herein.
