<p>combined imager and rangefinder includes an imaging sensor and an illuminator. The sensor acquires images of objects in a FOV. The illuminator directs a beam of light via the FOV. In a first mode, the sensor acquires full images of the whole FOV. In a second mode, the sensor acquires partial images, of only part of the FOV, that include a reflection of the light from one of the objects. The range to the object is determined from the location of the reflection in the partial images. Successive range measurements are used to determine whether a collision with the object is imminent.</p> |
