Abstract: A method for testing a vehicular camera for a vehicular vision system includes providing a vehicular camera suitable for use on a vehicle, with the vehicular camera having a field of view. A collimator assembly is provided that includes an optic and a target fixedly disposed within the collimator assembly. The collimator assembly is positioned in the field of view of the vehicular camera such that the camera images light that reflects off the target and passes through the optic. The target has a stepped surface. Image data is captured with the vehicular camera, with the captured image data being representative of the stepped surface of the target. The captured image data is processed, via an image processor, and a defocus of the vehicular camera is estimated based on processing by the processor of the captured image data of the stepped surface of the target.

Abstract: A method for assembling an imager assembly for a vehicular camera includes providing a lens barrel that accommodates a lens, providing a lens holder, and providing a PCB with an imager disposed thereat. A cylindrical portion of the lens barrel is disposed in a cylindrical passageway of the lens holder and the PCB is disposed at the lens holder. An adhesive is dispensed to hold the lens optically aligned with the imager. After the lens is optically aligned with the imager, the adhesive is initially cured to an initially-cured state in an initial curing process for an initial-cure time period. The adhesive is further cured to a further-cured state in a secondary curing process for a longer further-cure time period. As further cured, the further-cured adhesive maintains optical alignment of the lens with the imager for use of the imager assembly in a vehicular camera in a vehicle.

A collimator is provided that includes an optic and a target. The collimator is positioned in the field of view of the vehicular camera such that the camera images light that reflects off the target and passes through the optic. The target is angled or stepped relative to an image plane of the vehicular camera. Image data is captured with the vehicular camera, with the captured image data being representative of the angled or stepped target. The captured image data is processed, via an image processor, and a defocus of the vehicular camera is estimated based on processing by the processor of the captured image data of the angled or stepped target.

Abstract: A method for assembling a vehicular camera module includes providing an imager circuit board and a lens holder. The lens holder includes a lens holding portion and an attaching portion, with the lens holding portion accommodating a lens. The attaching portion of the lens holder includes pins that, when the attaching portion is located at the imager circuit board, are received at least partially through apertures of the imager circuit board. With the pins received at least partially through the apertures, the lens holder is laterally adjusted relative to the imager circuit board and the pins are soldered at the imager circuit board so as to attach the lens holder at the imager circuit board to form an imager assembly. The imager assembly is attached at a camera housing, and a processing circuit board is accommodated at the camera housing and electrically connected to the imager circuit board.

Abstract: A method of assembling a vehicular camera includes providing a printed circuit board and dispensing an adhesive in an uncured state at the printed circuit board. A front camera housing is mated with the circuit board, and the lens optics are aligned with respect to the imaging array at the circuit board by utilizing a multi-axis positioning device operable to translate the circuit board or lens assembly relative to the other along one or more orthogonal translational axes and manipulate the circuit board or lens assembly relative to the other about one or more orthogonal rotational axes. After aligning the lens optics with respect to the imaging array, the adhesive is cured to a first cure level and the joined lens assembly and the front camera housing are moved to a further curing station, where the adhesive is further cured to a second cure level.

Abstract: A vehicular camera includes a lens, a printed circuit board and an imager. The lens has a plurality of optical element and is disposed at a lens holder. The imager is disposed at the printed circuit board. The adhesive is initially curable in an initial radiation curing process that comprises exposure to UV light, and initially-cured adhesive is further curable to a further cured strength in a secondary thermal curing process. The adhesive is initially cured via the initial radiation curing process after the lens is brought into focus with the imager and is optically center-aligned therewith. The initially-cured adhesive, as cured via the initial radiation curing process, holds the lens optically center-aligned and in focus with the imager. After the initial radiation curing process, the lens holder, adhesively attached to one of the printed circuit board and the holding element, is moved to the secondary thermal curing process.

Abstract: A method of assembling a vehicular camera includes providing a lens assembly having a base portion, a lens barrel and a plurality of optical elements in the lens barrel, and providing a circuit element having a circuit board and an imaging array. An adhesive bead is dispensed at the base portion and/or circuit element. The circuit element is placed at the base portion with the adhesive bead therebetween and the optical elements are aligned with the imaging array via a six axis robotic device when the circuit element is at the base portion and in contact with the adhesive bead. The adhesive bead is cured to a first cure level via exposure of the adhesive bead to ultraviolet light. The assembly is moved to a second curing stage and the adhesive bead is cured to a second cure level via heating the adhesive bead.
