Abstract: A tracking and ranging system includes a thermal sensor device, a controller, a ranging device and a transmission device. The thermal sensor device is configured to capture a thermal image. The controller analyzes the thermal image to identify the main heat source from among the heat sources displayed in the thermal image, and obtain an offset distance between the center points of the main heat source and the thermal image. The ranging device is coupled to the controller. The transmission device loads the ranging device and is coupled to the controller. The controller controls the motion of the transmission device in accordance with the offset distance to correct the offset angle between the ranging device and the object corresponding to the main heat source. After correcting the offset angle, the ranging device detects a first distance to the object by transmitting energy and receiving reflected energy.
