Abstract: An information processing device includes a VSLAM processing unit as an acquisition unit, a difference calculation unit and an offset processing unit as alignment processing units, and an integration unit as an integration processing unit. The VSLAM processing unit acquires first point cloud information based on first image data obtained from a first image capturing unit provided at a first position of a moving body, and acquires second point cloud information based on second image data obtained from a second image capturing unit provided at a second position different from the first position of the moving body. The difference calculation unit and offset processing unit perform alignment processing on the first and second point cloud information. The integration unit generates integrated point cloud information by using the first point cloud information and the second point cloud information on both of which the alignment processing has been performed.

Abstract: In one aspect, an image processing apparatus includes a determination unit and a deformation unit. The determination unit executes first distance stabilization processing of converting a measurement distance between a three-dimensional object around a moving object and the moving object into a first distance or a second distance smaller than the first distance as a stabilization distance based on the magnitude relation between the measurement distance and the first threshold. The deformation unit deforms a projection surface of a peripheral image of the moving object based on the stabilization distance.

Abstract: An information processing device includes a memory and a processor configured to obtain first point group information that represents three-dimensional positional information, by using image data captured by a first camera; output second point group information obtained by reducing noise of the first point group information, by using one or more filters; and set filter coefficients of the one or more filters, by using (i) a filter coefficient estimation model trained in advance by using (a) test data for learning that includes image data captured by a second camera and (b) training data based on third point group information that represents three-dimensional positional information obtained by a position sensor, and (ii) observation data that includes the image data captured by the first camera.

Abstract: In an aspect, an image processing device includes a hardware processor configured to function as a determination unit and an image generation unit. The determination unit determines a boundary region in a region where spatially adjacent peripheral images of a plurality of peripheral images of a moving body overlap with each other, using position information including a plurality of detection points around the moving body and self-position information of the moving body. The image generation unit generates a combined image, using the spatially adjacent peripheral images, using the boundary region.

Abstract: An image processing apparatus is disclosed. The image processing apparatus includes a processor connected to a memory. The processor functions as a deformation unit. The deformation unit serves to deform a reference projection screen that is a projection screen of a surrounding image of a moving object. The reference projection screen is deformed by using position information in which detection points around the moving object are accumulated and using self-location information of the moving object.

Abstract: A distance measurement system includes a pair of cameras and is arranged on a roof of a mobile object or an upper edge portion of a door of the mobile object. One of the cameras is arranged at a first portion on an upper surface of the roof or on the upper edge portion of the door, includes an optical axis oriented upward from the upper surface, and has a field of view in all directions around the optical axis. The other camera is arranged at a second portion different from the first portion on the upper surface of the roof or the upper edge portion of the door, includes an optical axis oriented upward from the upper surface, and has a field of view in all directions around the optical axis. Distance measurement in all directions from the mobile object is performed by using this pair of cameras.

Abstract: The phase offset circuit of the present invention realizes a phase offset of a multiple of 90° by inverting the sign of signed binary data first, and then adjusts the amplitude of the signal. Finally, the phase offset calculator realizes a phase offset with a rotation angle smaller than 90° (for example, a fixed 45° offset).
