Abstract
An object detection system of a vehicle includes a time-of-flight (TOF) sensor that receives a reflected object detection signal at a second time based on an object detection signal transmitted at a first time. An image sensor generates an image signal including an image of a detected object. The image sensor is distinct from and adjacent to the TOF sensor. A TOF control module generates distance data based on the first time and the second time and determines whether at least a portion of a detected object is within a predetermined distance of the vehicle. An image control module generates image data based on the image signal. A detection control module correlates the distance data with the image data to generate a warning indicator when at least a portion of the detected object is within the predetermined distance of the vehicle.
