Auto-calibration of vehicle sensors
A system for automatically calibrating sensors of a vehicle includes an electronic control unit, a projector communicatively coupled to the electronic control unit, a first sensor communicatively coupled to the electronic control unit, and a second sensor communicatively coupled to the electronic control unit. The electronic control unit is configured to project, with the projector, a calibration pattern onto a surface, capture, with the first sensor, a first portion of the calibration pattern, capture, with the second sensor, a second portion of the calibration pattern, and calibrate the first sensor and the second sensor based on at least one feature sensed within the first portion of the calibration pattern and the second portion of the calibration pattern.
Vehicular forward viewing image capture system
A vehicular forward viewing image capture system includes an accessory module configured for attachment at an in-cabin side of a windshield of a vehicle, whereby a CMOS image sensor views through the windshield forward of the vehicle. With the accessory module attached at the in-cabin side of the windshield, and while the vehicle is traveling along a road, captured image data is processed to determine movement of an object of interest viewed by the image sensor. Multiple frames of captured image data are processed in determining movement of the object of interest. The accessory module includes an electrical connector for electrically connecting to a vehicle wiring system of the vehicle. Image data captured by the image sensor may be processed for an automatic headlamp control system of the equipped vehicle. The vehicular forward viewing image capture system may compensate for misalignment of the image sensor.

SEARCHLIGHT CONTROL SYSTEMS AND METHODS FOR MOVING A BEAM OF LIGHT EMITTED BY A SEARCHLIGHT ON A MOBILE PLATFORM AT A CONSTANT GROUND SPEED
Systems and methods for moving an illumination spot of a searchlight beam at a constant groundspeed. The method includes receiving state data comprising an attitude for the mobile platform. The method computes an elevation angle, theta, of the beam as a function of the attitude, an elevation actuator angle and a known mounting orientation for the searchlight. Responsive to receiving a searchlight control command from a user input device, the method determines a respective rate of change of theta, dtheta/dt, and rate of change of Psi, dPsi/dt, required to maintain the constant groundspeed of the illumination spot, as a function of the state data. The method updates theta responsive to the determined dtheta/dt and generates actuator control commands for an elevation actuator based thereon. The method updates Psi responsive to the determined dPsi/dt, and generates actuator control commands for an azimuth actuator based thereon.
