IMAGE DETECTION SYSTEM OF VEHICLE
First Claim
1. An image detection system of a vehicle for detecting at least one target object around the vehicle and further detecting a distance between the at least one target object and the vehicle, comprising:
- a light source unit externally provided on the vehicle and configured to comprise at least one light source for emitting a light beam used to show at least one optical pattern on the target object, the optical pattern varying according to the distance between the target object and the vehicle;
an image capturing unit externally provided on the vehicle corresponding to the light source unit, and comprising a lens, an image sensor connected to the lens, and a microprocessor connected to the image sensor, the lens capturing and transmitting an image of the target object and the optical pattern thereon to the image sensor, the microprocessor calculating the distance between the target object and the vehicle based on the varying optical pattern on the target object by combining a motion object detection (MOD) according to the varying image of the target object; and
an alarm unit electrically connected to the microprocessor and internally provided in the vehicle, wherein the microprocessor transmits a message to the alarm unit when the distance between the target object and the vehicle is smaller than a threshold value, and the alarm unit generates an alarm signal based on the received message.

Abstract
The present invention discloses an image detection system of a vehicle for detecting at least one target object around a vehicle, and further detecting a distance between the at least one target object and the vehicle. The image detection system of the vehicle at least includes a light source unit, an image capturing unit and an alarm unit. The present invention primarily employs a laser beam incident onto the target object to form at least one optical pattern, and variation of the optical pattern and a motion object detection are collocated to effectively calculate the distance between the target object and the vehicle, thereby achieving an advantage of alarming and alerting a driver to safety of driving.
