In some implementations, this invention is used for 3D scanning, i.e., for detection of the 3D position of points in a scene.

Abstract: An apparatus for extending binocular camera positioning range includes: a rotatable base, a positioning module, a judging module, and a controlling module. The rotatable base is disposed on the binocular camera and drives a lens of the binocular camera to rotate.

Abstract: Dynamic resolution switching achieves a target bitrate for single-pass and two-pass encoding of a video stream. A single-pass encoder determines whether an encoding bitrate for a frame meets a target bitrate. If not, a quantization parameter used to encode the frame is compared against minimum and maximum threshold values to determine whether the video resolution needs to be adjusted. A two-pass encoder encodes an input frame using a quantization parameter and determines whether video resolution for encoding the frame during a second pass may be adjusted based on the bitrate at which the input frame is encoded. The resolution may be adjusted based on encoder limitations with respect to a motion search area used to code a frame.

The camera may be provided on or within a vehicle and the person is an operator of the vehicle. Alternatively, the camera may be mounted in a stationary location within a working site.

Abstract: In an in-vehicle camera, when an in-vehicle camera body is hooked on a hook portion of a bracket attached to a windshield, a leaf spring presses the in-vehicle camera body against the bracket to fix the in-vehicle camera body to the bracket. Therefore, the in-vehicle camera body can be attached to the windshield without permitting the windshield to come off from the vehicle by the bracket's being strongly pushed such as by a jig, or without permitting the jig to scratch the windshield. Since the in-vehicle camera body is fixed to the bracket by being pressed against the bracket by the leaf spring, there is no problem of causing backlash relative to the bracket.

Abstract: A context switching method for video encoders that enables higher priority video streams to interrupt lower priority video streams. A high priority frame may be received for processing while another frame is being processed. The pipeline may be signaled to perform a context stop for the current frame. The pipeline stops processing the current frame at an appropriate place, and propagates the stop through the stages of the pipeline and to a transcoder through DMA. The stopping location is recorded. The video encoder may then process the higher-priority frame. When done, a context restart is performed and the pipeline resumes processing the lower-priority frame beginning at the recorded location. The transcoder may process data for the interrupted frame while the higher-priority frame is being processed in the pipeline, and similarly the pipeline may begin processing the lower-priority frame after the context restart while the transcoder completes processing the higher-priority frame.
