A sensor calibration system for a vehicle includes one or more processors. The system also includes a memory communicably coupled to the one or more processors and storing a sensor calibration module including instructions that when executed by the one or more processors cause the one or more processors to, for an environment sensor of the vehicle, determine if the sensor can detect at least a predetermined number of viable reference features in an environment of the vehicle. The module also includes processor-executable instructions to, if the sensor cannot not detect at least a predetermined number of viable reference features, determine at least one suggested positional arrangement of viable reference features with respect to a current position the sensor. The module also includes processor-executable instructions to generate instructions to arrange viable reference features in the at least one suggested positional arrangement.

System and method to facilitate calibration of sensors in a vehicle

A system for determining the rigid-body transformation between 2D image data and 3D point cloud data includes a first sensor configured to capture image data of an environment, a second sensor configured to capture point cloud data of the environment; and a computing device communicatively coupled to the first sensor and the second sensor. The computing device is configured to receive image data from the first sensor and point cloud data from the second sensor, parameterize one or more 2D lines from image data, parameterize one or more 3D lines from point cloud data, align the one or more 2D lines with the one or more 3D lines by solving a registration problem formulated as a mixed integer linear program to simultaneously solve for a projection transform vector and a data association set, and generate a data mesh comprising the image data aligned with the point cloud data.

2D to 3D line-based registration with unknown associations

In one embodiment, a system for locating a mobile phone in a vehicle is provided. The system includes one or more processors and a memory communicably coupled to the one or more processors and storing a detection module and a safety module. The detection module including instructions that when executed by the one or more processors cause the one or more processors to: determine that a mobile phone is located in a vehicle. The safety module including instructions that when executed by the one or more processors cause the one or more processors to: in response to the determination, play a sound in the vehicle; record the sound played in the vehicle; based on the recorded sound and a sound model, determine if the mobile phone is in a driver seat of the vehicle; and if it is determined that the mobile phone is in the driver seat of the vehicle, disable at least some functionality of the mobile phone.
