  • Publication number: 20210088441
    Abstract: A deposit detection device according to an embodiment includes a calculation module, a detection module, an interpolation module, and a state management module. The calculation module calculates a region feature amount based on an edge vector of each pixel, for each unit region composed of a predetermined number of pixels included in a captured image. The detection module detects the unit region corresponding to a partial covering location and the unit region corresponding to a diffuse reflection location based on a detection condition and a second detection condition, respectively, the first detection condition and the second detection condition being based on the region feature amount. The interpolation module interpolates the area ratio of the partial covering location reduced due to the diffuse reflection location. The state management module controls state transitions of states related to interpolation of the area ratio, based on increase and decrease of the diffuse reflection location.

  • Publication number: 20210090297
    Abstract: An adhered substance detection apparatus of an embodiment includes a calculator and a determiner. The calculator calculates an edge feature for each cell based on edge vectors of pixels within the cell in a captured image, and further calculates a region feature for each unit region based on the calculated edge features of the cells within the unit region. The determiner determines an adherence state of an adhered substance on a lens of a camera based on the region feature. The calculator calculates, as the region feature, number of the cells having an edge strength of zero. When the number of the cells having the zero edge strength is equal to or greater than a predetermined number in a predetermined attention area in the captured image, the determiner determines not to perform a determination for detecting whether the lens of the camera is entirely covered by the adhered substance.

  • Publication number: 20210089809
    Abstract: A deposit detection device according to an embodiment includes a detection module, a determination module, and an identification module. The detection module detects a deposit region corresponding to a deposit adhering to an imaging device, based on brightness information of an image captured by the imaging device. The determination module determines whether variation in brightness information in a predetermined region of the image is within a predetermined range, in a period after a vehicle is stopped in a state in which the deposit region is detected by the detection module. The identification module identifies brightness information serving as a determination criterion of the deposit region when the determination module determines that the variation in brightness information is within a predetermined range.

  • Publication number: 20210090236
    Abstract: A deposit detection device according to an embodiment includes a detection module and a storage processing module. The detection module detects a deposit region corresponding to a deposit adhering to an imaging device, based on brightness information of an image captured by the imaging device. The storage processing module stores deposit information on the deposit region in a storage unit that is nonvolatile, when an ignition power of a vehicle is turned off in a state in which the deposit region is detected. For an initial detection process after the ignition power is turned on, the detection module detects the deposit region based on the deposit information stored in the storage unit.

  • Publication number: 20210089818
    Abstract: A deposit detection device according to an embodiment includes a detection module, an extraction module, and an identification module. The detection module detects a candidate region for a deposit region corresponding to a deposit adhering to an imaging device, based on brightness information for each of small regions into which a predetermined region in an image captured by the imaging device is divided. The extraction module extracts, as a boundary region, the small region in which a brightness difference value from the small region adjacent to the small region is equal to or larger than a predetermined threshold value, from among the small regions included in the candidate region detected by the detection module. The identification module identifies the candidate region as the deposit region when the number of boundary regions extracted by the extraction module satisfies a predetermined identification condition.
