3D-NIR enlarged creation image system and method,MX/a/2022/016091

The invention corresponds to the field of electronics and systems engineering applied to optics and presents a solution to the problem of taking 2D/3D images in conditions of low or no illumination, dust, fog, rain, snow or smoke. It is a vision system that operates on the principle of a single pixel with active illumination in the 1550 nm wavelength in combination with an indirect time-of-flight (ITOF) system in the 850 nm wavelength. The generation of 2D images is performed by the system that controls the data management and processing. For the imaging process, a series of light patterns are projected onto the scene to detect relevant objects. The reflected light is captured through the use of an InGaAs photodiode to be processed and generate the 2D image. This, together with the signals from the ITOF system, determines the depth map that will be used to determine the third dimension of the object and obtain the 3D image.

 

Hybrid 3D imaging system,MX/a/2020/012197

The invention corresponds to the field of electronics and systems engineering applied to optics and represents a solution to the problem of taking 2D/3D images in conditions of limited vision due to rain, fog, or other situations that limit visibility. This hybrid vision system operates on the principle of a single-pixel with active wavelength illumination active illumination in the 1550 nm wavelength in combination with a laser array working on the principle of indirect time-of-flight (iToF) and millimeter radar. The generation of 2D images is carried out by the system that controls the data management and processing. A series of light patterns are projected onto the scene for the generation process to detect objects. The reflected light is captured using an InGaAs photodiode and processed to generate the 2D image. In conjunction with the laser signals and the electromagnetic signals from the radar, radar electromagnetic signals determine the depth map used to determine the object's third dimension and obtain the 3D image.
