Test system for verification of front camera lighting features

A method of testing a vehicular camera for a vehicular vision system, the method comprising:

• providing a vehicular camera suitable for use on a vehicle, wherein the vehicular camera has a field of view;
• providing a display screen that displays video images;
• providing a light emitting diode (LED) matrix comprising a plurality of LEDs operable to emit patterns of light of different colors;
• providing a partially light reflecting and partially light transmitting mirror;
• positioning the vehicular camera at a structure;
• positioning the LED matrix in the field of view of the vehicular camera;
• positioning the mirror in the field of view of the vehicular camera between the vehicular camera and the LED matrix;
• positioning the display screen in the field of view of the vehicular camera as viewed as a reflection off the mirror;
• providing a simulator control that generates video control signals and LED control signals;
• responsive to video control signals, displaying video images via the display screen;
• responsive to LED control signals, emitting patterns of light via the LED matrix;
• wherein the emitted patterns of light are imaged by the vehicular camera through the mirror;
• wherein the displayed video images reflect off the mirror and are imaged by the vehicular camera;
• and
• capturing image data with the vehicular camera, wherein the captured image data is representative of the displayed video images and the emitted patterns of light imaged by the vehicular camera.

• positioning the LED matrix in the field of view of the vehicular camera as viewed as a reflection off the mirror;
• wherein the mirror is angled at 45 degrees relative to an image plane of the vehicular camera, and wherein a display plane of the display screen is parallel to the image plane, and wherein an LED plane of the LED matrix is perpendicular to the image plane;
• providing a simulator control that generates video control signals and LED control signals;
• responsive to video control signals, displaying video images via the display screen;
• responsive to LED control signals, emitting patterns of light via the LED matrix;
• wherein the patterns of light emitted by the LED matrix are representative of vehicle headlights and/or vehicle taillights;
• wherein the displayed video images are imaged by the vehicular camera through the mirror;
• wherein the emitted patterns of light reflect off the mirror and are imaged by the vehicular camera;
• and
• capturing image data with the vehicular camera, wherein the captured image data is representative of the displayed video images and the emitted patterns of light imaged by the vehicular camera.
