Object detection apparatus, especially for vehicles

摘要

An object detection apparatus has a laser radar and near infrared ray projector 1, an electronic control unit (3) and a near infrared camera (4). The laser radar and near infrared ray projector 1 has a near infrared ray projecting lens (11), a laser oscillator (21), a laser receiver (22) and a swivel actuator (23). The laser oscillator (21) emits a laser beam, while the swivel actuator (23) scans the laser beam in a laser scanning range (A). The laser receiver (22) receives the laser beam reflected on an object. The near infrared ray projecting lens (11) diverges the laser beam emitted from the laser oscillator (21) and projects a near infrared ray into a range including the laser scanning range (A) and a near infrared ray projecting range (C). The near infrared camera (4) obtains an infrared image by receiving a near infrared ray reflected on the object. The electronic control unit (3) calculates object information based on the received laser beam when detecting an object and causes the near infrared ray to be projected to obtain the infrared image when acquiring the infrared image.
