Abstract: A laser pointing device having a thermal detection function is applied in a garage to guide a driver to park a car. The laser pointing device has a thermal detector, a laser diode, and a drive module. The thermal detector is used to detect the temperature of the ambient environment. The drive module is electrically connected between the thermal detector and the laser diode. When the thermal detector detects that the temperature of the ambient environment exceeds a threshold temperature, the drive module will drive the laser diode to emit a laser light beam. Thereby, when a driver parks his car in a garage, the laser light beam will be emitted to guide him to park the car after the thermal detector detects that the temperature of the car's engine exceeds the threshold temperature.
