Abstract: The present disclosure relates to an information processing apparatus capable of detecting a plane constituting a movement-enabling region, as well as to an information processing method, a program, and a mobile object.A normal direction of a plane constituting a road surface is detected on the basis of polarized images in multiple polarizing directions acquired by a polarization camera. A laser ranging sensor measures a distance to a point on the road surface so as to measure a position of the point. The plane constituting the road surface is identified on the basis of information regarding the normal direction of the plane constituting the road surface and information regarding the position of the point on the road surface. This disclosure may be applied to vehicle-mounted systems.

Abstract: This technology relates to a signal processing apparatus and a signal processing method for obtaining the relative positional relations between sensors with higher accuracy. A positional relation estimating part of the signal processing apparatus estimates positional relations between a first coordinate system and a second coordinate system, on the basis of corresponding relations between multiple planes in the first coordinate system obtained by a first sensor on the one hand and multiple planes in the second coordinate system obtained by a second sensor on the other hand. This technology may be applied, for example, to the signal processing apparatus that estimates the positional relations between the first and the second sensors having significantly different levels of spatial resolution.

Abstract: A recognition processing section performs subject recognition in a processing area of an image obtained by an imaging section. The recognition processing section determines an image characteristic of the processing area on the basis of a characteristic map indicating an image characteristic of the image obtained by the imaging section and uses a recognizer corresponding to the image characteristic of the processing area. The characteristic map includes a map based on an optical characteristic of an imaging lens used in the imaging section and is stored in a characteristic information storage section. An imaging lens has a winder angle of view in all directions or in a predetermined direction than a standard lens, and the optical characteristic thereof differs depending on a position on the lens. The recognition processing section performs the subject recognition using a recognizer corresponding to resolution or skewness of the processing area, for example.

Abstract: On the basis of semantic labeling information in an image captured by a camera an area in which a boundary of a movable area of a mobile body exists in the image is estimated as an image movable area boundary, on the basis of a distance image detected by a depth sensor an area in which the boundary of the movable area of the mobile body exists in the distance image is estimated as a distance image movable area boundary, the boundary of the movable area is determined on the basis of the image movable area boundary and of the distance image movable area boundary, and an environment map is generated on the basis of the determined boundary of the movable area. The present disclosure can be applied to an in-vehicle system.

Abstract: The present disclosure relates to a signal processing apparatus and system. In calibration, a sensor section is used to acquire a time of day when a stereo camera image capturing a target is acquired and a time of day when a radar image capturing the target is acquired. The target has a radar reflector and a marker. The image acquisition times of day are acquired while at the same time changing a distance between the sensor section and the target so as to find an amount of time-of-day discrepancy, a difference in time of day between the stereo camera image and the radar image at the same distance. At the time of object detection, the radar image acquired first is buffered and then output together with the stereo camera image acquired by the time-of-day discrepancy later, thus combining the stereo camera image and the radar image.

Abstract: A laser range finder projects light while changing a direction in a horizontal direction at a predetermined angle with respect to a vertical direction to also receive reflected light of the light, and detects a direction and a distance in which the light is reflected from an obstacle or the like, according to a difference time between a time of light projection and a time of light reception. A normal direction of a flat plane forming a road surface is detected on the basis of a polarized image. The laser range finder projects light such that the light has a predetermined angle with respect to the vertical direction so as to be orthogonal to the normal direction of the flat plane forming the road surface. The laser range finder can be applied to in-vehicle systems.
