Abstract: A method for stitching images captured by multiple vehicular cameras includes disposing a plurality of cameras at the vehicle so as to have respective fields of view exterior the vehicle. Image data captured by first and second cameras of the plurality of cameras is processed to detect an object present in an overlapping portion of the fields of view of the first and second cameras. Image data captured by the first and second cameras is stitched, via processing provided captured image data, to form stitched images. Stitching of captured image data is adjusted responsive to determination of a difference between a characteristic of a feature of a detected object as captured by the first camera and the characteristic of the feature of the detected object as captured by the second camera in order to mitigate misalignment of stitched images.

Abstract: A monitoring system monitors a monitoring object apparatus sufficiently for practical use while suppressing battery power consumption. The monitoring system is provided a sensor terminal that is driven by a battery and acquires a measured value(s) of a measuring apparatus mounted in the monitoring object apparatus by executing image analysis processing on a captured image(s) obtained by photographing the measuring apparatus. A manager terminal monitors the measured value(s) of the measuring apparatus which is reported from the sensor terminal. When the measured value is out of a normal range, the manager terminal requests transmission of image data of an image area, which is necessary to check whether the measured value of the measuring apparatus is actually out of the normal range or not. The sensor terminal transmits the requested image data with the requested resolution to the manger terminal in response to the request from the manager terminal.

Abstract: A depth sensing system receives an image pair showing objects in a scene. The system generates binary hashes for pixels in the image pair by performing a random walk. The system matches pixels in the first image to pixels in the second image that depict the same point in the scene by generating cost values representing differences between the binary hashes for pairs of pixels in the images. The system generates a disparity map containing disparity vectors representing coordinate differences between matched pixels in the first and second images. The system generates and outputs a depth map based on the disparity map. The depth map represents the distances between an image acquisition system that acquired the image pair and the objects in the scene.
