A vehicle headlamp alignment system is provided that includes a headlamp located on a vehicle, an adjuster module for adjusting aim of the headlamp, and a camera located on the vehicle. Sensors may determine distance and orientation of the vehicle relative to a wall. A controller processes images of a beam on the wall acquired by the camera and determines the aim of the headlamp based on the images. The controller controls the adjuster module to align the headlamp based on the determined aim.

A vehicle may have lights such as headlights. The lights may be moved using a positioner. Control circuitry in the vehicle may use sensor circuitry to monitor the environment surrounding the vehicle. The sensor circuitry may include one or more sensors such as a lidar sensor, radar sensor, image sensor, and/or other sensors to measure the shape of a surface in front of the vehicle and the location of the surface relative to the vehicle. These sensors and/or other sensors in the sensor circuitry also measure headlight illumination on the surface. Based on the known shape of the surface in front of the vehicle and the distance of the surface from the vehicle, the control circuitry can predict where a headlight should be aimed on the surface. By comparing predictions of headlight illumination on the surface to measurements of headlight illumination on the surface, the vehicle can determine how to move the headlight with the positioner to align the headlight.

It is possible to cope with a deviation of a relative position between a headlight and an in-vehicle camera. An in-vehicle system includes: an irradiation unit that irradiates an area other than a set light-shielding range with light; an imaging unit that images a range including an irradiation range of the light emitted by the irradiation unit to acquire a captured image; an object detection unit that detects a non-target object which is not to be irradiated with the light from the captured image; a direct irradiation prevention unit that calculates the light-shielding range on the basis of a position of the non-target object in the captured image and correction information, and sets the light-shielding range in the irradiation unit; a correction-time light-shielding range setting unit that sets the predetermined light-shielding range in the irradiation unit; and a correction calculation unit that calculates the correction information on the basis of the captured image when the correction-time light-shielding range setting unit sets the light-shielding range in the irradiation unit.

A method for checking the plausibility of detected features of a light distribution of a headlamp of a motor vehicle includes irradiating, by the headlamp, a scene in surroundings of the motor vehicle; capturing, by a camera of the motor vehicle, the irradiated scene in an image; dynamically seeking and identifying at least one initial optical feature in the image, adaptively producing and analyzing local surroundings of the at least one initial optical feature; dynamically extracting at least one further optical feature from the local surroundings; and carrying out, using a learned algorithm and on the basis of the at least one initial optical feature and the at least one further optical feature, an adaptive check as to whether the at least one initial optical feature and the at least one further optical feature are plausibly arranged in the local surroundings.

A vehicle headlamp aiming system includes a displaceable aiming surface and an imaging system. The imaging system includes an indexing aim box having at least one imager oriented to capture images of a headlamp and/or one or more vehicle features adjacent to the headlamp and at least one fixed imager oriented to capture one images of the displaceable aiming surface to determine a headlamp cutoff height. The displaceable aiming surface is configured to selectively displace to allow passage of the vehicle. The indexing aim box is configured to translate between the headlamp and another headlamp. One or more computing devices are configured to perform methods for headlamp aim correction using the described system. The methods include providing image inputs from the imaging system and calculating therefrom an aim correction of the headlamps.

The invention relates to a method for calibrating a lighting apparatus, particularly lighting apparatus for a motor vehicle.

There is provided an aiming adjustment method for a vehicle headlamp which performs aiming adjustment based on a reference point on a light-dark boundary of a light distribution pattern, the method includes setting, as the reference point, an intersection between a vertical light-dark boundary of a part of multi-divided light distribution patterns which are to be synthesized to form a high-beam light distribution pattern and a horizontal light-dark boundary of a low-beam light distribution pattern.

The invention provides a method for correcting a first light pattern provided by a lighting device (1) with a matrix of light sources (2). This method comprising the steps of obtaining a map of the light pattern divided in pixels (4), associating a calibration power value to each pixel (4), depending on the light intensity of each pixel and assigning a new power value to each pixel. Finally, a corrected light pattern is projected with the new power values. The invention also provides an automotive lighting device with a calibrator to perform the steps of this method and an automotive lighting assembly with an external calibrator to perform the steps of this method.

The present disclosure relates to a method for calibrating a position of a matrix headlamp of a motor vehicle by means of a camera of the motor vehicle, wherein the matrix headlamp has a plurality of segments controllable independently of one another for light emission. At least one first image of a sign is recorded by means of the camera, a location area in which the sign is arranged is determined, illuminance of a first segment is changed, at least one second image is recorded and checked, whether a change in a glare effect detected on the basis of the at least one recorded second image has occurred, and if so, the position of the matrix headlamp is calibrated depending on the first segment and position information derived from the location area.
