Abstract: Among other things, techniques are described for calibrating a sensor of a vehicle. One technique involves identifying a trigger for calibrating at least one sensor of a vehicle. In response to identifying the trigger, the technique then involves initiating a calibration path planning mode for the vehicle. In the calibration path planning mode, the technique involves: generating a plurality of calibration-aware paths that each include at least one calibration trajectory along at least one road; and selecting, from the plurality of paths, a first calibration-aware path for the vehicle, where the at least one sensor is calibrated while the vehicle travels along the selected path.

Abstract: An automatic calibration and validation pipeline is disclosed to estimate and evaluate the accuracy of extrinsic parameters of a camera-to-LiDAR coordinate transformation. In an embodiment, an automated and unsupervised calibration procedure is employed where the computed rotational and translational parameters (“extrinsic parameters”) of the camera-to-LiDAR coordinate transformation are automatically estimated and validated, and upper bounds on the accuracy of the extrinsic parameters are set. The calibration procedure combines three-dimensional (3D) plane, vector and point correspondences to determine the extrinsic parameters, and the resulting coordinate transformation is validated by analyzing the projection of a filtered point cloud including a validation target in the image space. A single camera image and LiDAR scan (a “single shot”) are used to calibrate and validate the extrinsic parameters.

Abstract: The invention provides a device, embedded in an electronic equipment, for assisting in processing a media content based on a subscribed syndication feed. The invention utilizes a widget engine module to perform a widget application to parse the subscribed syndication feed to obtain link tags, to download media data based on the link tags, and to generate the media content based on the parsed subscribed syndication feed, the media data and a user interface provided by the widget engine module. Thereby, a user can use the electronic equipment to, over the internet, subscribe and download information of interest, shared media content or other specific services or tools.

Abstract: A plant water absorbing container is disclosed. A water tank is filled with water. At least one supporting frame is disposed in the water tank. A net frame slight smaller than the opening of the water tank is installed above the supporting frame. A plurality of water absorbing cottons are disposed above the net frame. Two distal ends of each water absorbing cotton are sunk in the water. Each position on the net frame for disposing the water absorbing cotton is installed with a flat culture disk. Each culture disk has a bottom which is drilled with a plurality of via holes. Each culture disk is filled with nourish material and plant. The water absorbing cotton generates a siphonage so that water permeates into the water absorbing cotton from the center portion thereof. The air for the root of a plant can flow through the hole at the lateral hole of the water tank. Therefore, plant will acquire sufficient nutriment and water.
