摘要： A processing system for cross-sensor calibration is configured to perform a first edge detection process on a camera image to generate an edge detected camera image, and perform a second edge detection process on a point cloud frame to generate an edge detected point cloud frame. The processing system projects the edge detected point cloud frame onto the edge detected camera image using an initial calibration matrix, determines an objective function representing an overlap of points in the edge detected point cloud frame and corresponding edge pixel values in the edge detected camera image, and determines a final calibration matrix based on the objective function.

摘要： There is provided a signal processing device and a signal processing method capable of accurately acquiring distance information in a case where a transparent subject is present. The signal processing device includes an acquisition unit that acquires histogram data of a flight time of irradiation light to a subject, a transparent subject determination unit that determines whether or not the subject is a transparent subject on the basis of peak information indicated by the histogram data and three-dimensional coordinates of the subject calculated on the basis of the histogram data, and an output unit that outputs the three-dimensional coordinates of the subject in which color information or three-dimensional coordinates of the subject is corrected on the basis of a transparent subject determination result of the transparent subject determination unit. The technology of the present disclosure can be applied to, for example, a signal processing device and the like that corrects distance information acquired by a ToF sensor of a direct ToF system.

摘要： A virtual wave creation system comprises an eyewear device that includes a frame, a temple connected to a lateral side of the frame, and a depth-capturing camera. Execution of programming by a processor configures the virtual wave creation system to generate, for each of multiple initial depth images, a respective wave image by applying a transformation function that is responsive to a selected input parameter to the initial three-dimensional coordinates. The virtual wave creation system creates a warped wave video including a sequence of the generated warped wave images. The virtual wave creation system presents, via an image display, the warped wave video.

摘要： The disclosure reduces an object shape estimation error even if an abnormality occurs in a device for obtaining a distance to the object. An information processing apparatus according to the disclosure obtains foreground information indicating regions corresponding to a foreground object in images captured by multiple image capturing devices that capture images of an image capturing region from varying directions, and distance information indicating a distance from a reference point to the foreground object, and obtains three-dimensional shape data indicating a foreground object three-dimensional shape based on the foreground information and the distance information. If the distance information is unobtainable by a first obtaining method, the information processing apparatus obtains the distance information by a second obtaining method, and at least one of the first and second obtaining methods uses at least part of the multiple image capturing devices as a stereo camera to obtain the distance information.

The image descattering method based on the iterative optimization of the atmospheric transmission matrix provided by the present application is based on the atmospheric transmission matrix.
