摘要： A system for quantitively determining quality for pavement markings disposed along pavement on a roadway includes one or more controllers in wireless communication with a plurality of vehicles. The one or more controllers receive image data represents the pavement markings disposed along the pavement collected by the plurality of vehicles. The one or more controllers execute instructions to determine at least one of a color distance measurement between a mean color space value of the pavement markings and an ideal marking color space value and a marking intensity contrast ratio between the pavement markings and the pavement.

摘要： A lane line recognition apparatus includes an imaging device, a lane-line-search-region setting section, a light-streak-search-region setting section, a light-streak determination section, a light-streak-reaching determination section, and a mask processing section. The imaging device is to be mounted on a vehicle and captures an image of a traveling environment in front of the vehicle. The lane-line-search-region setting section sets a lane-line search region on the image. The light-streak-search-region setting section sets a light-streak search region adjacently to the lane-line search region. The light-streak determination section determines whether a light streak that crosses, in a vertical direction of the image, the light-streak search region is found. The light-streak-reaching determination section determines, if the light streak is found, whether the light streak reaches the lane-line search region. The mask processing section performs, if the light streak reaches the lane-line search region, a mask process on the light streak.

摘要： A turbine blade or vane inspection apparatus comprising a controller, mounting for holding a turbine blade or vane, a source of illumination, and a camera. At least two of the source of illumination, the camera, and the mounting are moveable components. The controller is configured to control the moveable components to (a) position the turbine blade or vane mounted thereon relative to the illumination source so as to provide a contrast of illumination between a feature of the turbine blade or vane and an adjacent surface of the turbine blade or vane and (b), position the camera so that the optical axis of the camera is directed towards the feature. The controller is further configured to determine a dimension and/or shape of the feature based on an image obtained by the camera.

摘要： A method for encoding a point cloud feature includes: obtaining an original point cloud, generating point-wise hybrid scale voxel features by conducting hybrid scale voxelization on the original point cloud; generating voxel-wise attention features using spatial features and voxel features of points in a voxel at each voxel scale; aggregating the hybrid scale voxel features and the attention features to obtain voxel-wise projection scale information; and mapping the voxel-wise projection scale information to pseudo image features at projection scales. In this way, points can be retained during voxelization, and a feature encoding network is guided by the attention features to be more attentive to interrelationships between points in the voxels, thereby increasing accuracy of three-dimensional object detection.
