Abstract: The present disclosure relates to an HMD, a control method for the head mounted display, an information processor, a display device, and a program that make it possible to estimate camera parameters of a camera mounted in the HMD without the awareness of a user wearing the HMD. At a timing when the HMD is displaying content including a VR image or an AR image, the camera mounted in the HMD captures an image of a calibration pattern displayed on an external display, executes calibration on the basis of the captured image of the calibration pattern, and estimates the camera parameters. At this time, the calibration pattern displayed on the external display is displayed with dimensions according to a positional relationship between the HMD and the external display. The present disclosure is applicable to the HMD.

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: A subject information acquisition unit 12 acquires imaged subject information indicative of attributes related to illumination for a subject from a taken image. A preset information selection unit 21 selects preset information as illumination setting information for setting an illumination environment according to a user operation. An illumination setting information adjustment unit adjusts the illumination setting information selected by the illumination setting information selection unit to illumination setting information corresponding to the subject on the basis of the imaged subject information acquired by the subject information acquisition unit. By simply selecting the preset information, it is possible to set easily an illumination environment for relighting, for example.

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.
