摘要： A method and apparatus for vehicle monitoring of infrastructure lighting, an example of which includes a vehicle having a camera, an inter-vehicle communication module and a controller. The controller is to identify a stationary infrastructure object within an image captured by the camera and identify, in response to determining that the stationary infrastructure object includes a lamp, whether the lamp is inoperable. The controller also is to send, via vehicle-to-infrastructure communication utilizing the inter-vehicle communication module, an alert to an infrastructure communication node indicating that the lamp is inoperable.

摘要： Systems, methods, and apparatuses are disclosed for predicting or estimating the value of a variable speed sign (VSS). Probe data is received from multiple vehicles associated with a road segment. Location values are derived from the probe data. Center distance values are calculated based on the location values and the road segment. Clusters are derived from the probe data. Center distance values are grouped according to the respective clusters and a lane is assigned to at least one cluster based on the center distance values. The speed of the cluster predicts or estimates the corresponding lane of the VSS.

摘要： A method and apparatus for classifying light detection and ranging sensor data are provided. The method includes transforming sensor data of the LIDAR into point cloud data, selecting a cell including a subset of the point cloud data, dividing the selected cell into a plurality of voxels, calculating a difference of gradients for the plurality of voxels, performing a first pass on the plurality of voxels to identify voxels that contain an object based the difference of gradients, performing a second pass on the plurality of voxels to identify voxels that contain the object by adjusting a voxel with at least one from among a jitter parameter and a rotation parameter, and outputting a centroid average of voxels identified as containing the object.

摘要： An in-vehicle system for identifying exit-only lanes and shared exit lanes on a roadway having a first camera for obtaining image data regarding lane markings on the roadway, a second camera for obtaining image data regarding exit signs, a lane marking detection module for detecting lane markings on the roadway, an exit sign detection module for detecting exit signs, and an exit sign analyzer for detecting arrows on the detected exit signs. The in-vehicle system categorizes detected lane markings as one of standard frequency dashed lane markings, high frequency dashed lane markings, and solid lane markings, and identifies an exit-only lane and a shared exit lane in response to the categorizations of the detected lane markings and characteristics of the detected arrows.

摘要： A three-dimensional imaging system for imaging an object of interest present in an area about a vehicle. The system includes a camera and a control module. The camera is configured to capture an image of the area about the vehicle including the object of interest. A control module of the system compares the captured image to previously captured model images including examples of the object of interest. The control module also identifies the object of interest in the captured image based on the comparison, and builds a three-dimensional reconstruction of the object of interest.

摘要： A vehicle and a method of controlling the vehicle are provided. The vehicle includes an image capture unit that is configured to acquire image information by imaging a forward view of the vehicle and an imaging device controller that is configured to determine whether a traffic sign that indicates speed limit information of a road is recognized abnormally based on the acquired image information. A navigation controller is configured to display either speed limit information stored in an imaging device database or speed limit information of the road stored in a map database in response to determining that the traffic sign is recognized abnormally.

摘要： A traffic sign recognition system includes a display for displaying caution information regarding a traffic sign ahead of a vehicle, and a processor configured to execute a viewing direction detecting module for detecting a viewing direction of a driver, a traffic sign detecting module for detecting the traffic sign, and a road surface condition detecting module for detecting a slippery road surface condition. The processor controls the display to display the caution information regarding the detected traffic sign when the detected viewing direction of the driver is different from a direction of the detected traffic sign, and controlling the display to refrain from displaying the caution information when the detected viewing direction of the driver matches the direction of the detected traffic sign. When the slippery road surface condition is detected, the processor controls the display to display the caution information regardless of the viewing direction of the driver.

摘要： An autonomous vehicle includes both a LIDAR sensor and a camera. A point cloud from the LIDAR sensor is processed to remove points corresponding to a ground plane and points having a reflectivity below a reflectivity threshold. The remaining points are grouped into clusters. Clusters having points satisfying a flatness threshold are then converted into 2D pixel positions in the output of the camera. Regions of interest including these 2D pixel positions are then analyzed to detect and interpret any road signs present.

摘要： Embodiments relate to methods for efficiently encoding sensor data captured by an autonomous vehicle and building a high definition map using the encoded sensor data. The sensor data can be LiDAR data which is expressed as multiple image representations. Image representations that include important LiDAR data undergo a lossless compression while image representations that include LiDAR data that is more error-tolerant undergo a lossy compression. Therefore, the compressed sensor data can be transmitted to an online system for building a high definition map. When building a high definition map, entities, such as road signs and road lines, are constructed such that when encoded and compressed, the high definition map consumes less storage space. The positions of entities are expressed in relation to a reference centerline in the high definition map. Therefore, each position of an entity can be expressed in fewer numerical digits in comparison to conventional methods.
