Abstract: A safety protection method for a laser projection apparatus is provided. The laser scanning apparatus includes a laser source, a laser source driver, a scanning mirror, and a light-outputting port. The laser source driver is configured to drive the laser source to emit a laser beam. The safety protection method includes the following steps. Firstly, after the laser projection apparatus is powered on, an optical path of the laser beam is adjusted, so that the laser beam is not ejected out from the light-outputting port. Then, the laser source driver is disabled. Then, a judging step is performed to judge whether an intensity of the laser beam is higher than a threshold level. If the intensity of the laser beam is higher than the threshold level, the laser source is turned off.
