Abstract
A locating method, a locator, and a locating system for head-mounted display (HMD) are proposed. The method includes the following steps. A locator is provided and disposed on the HMD, where the locator includes an image capturing device and a communication interface, and the locator is connected to the HMD via the communication interface. An image of a reference object is captured by the locator through the image capturing device in an operating space to generate a first reference object image. A relative position of the HMD and the reference object is calculated by the locator according to the first reference object image so as to obtain locating information of the HMD in the operating space, and the locating information is transmitted to the HMD by the locator.
