The embodiment of the invention provides a spatial position measurement method. The method comprises the steps: measuring the horizontal angles and vertical angles of at least known points at at least two measurement places and the horizontal angle and the vertical angle of at least one unknown point, and calculating the coordinates of the unknown point according to the coordinates of the known points and the measured values. For the unknown point, can the method finally calculate the coordinates of the unknown points only if the angle of the unknown point relative to a measurement device is measured. Therefore, a low-cost spatial positioning device which just meets the angle measurement requirements can be used for measurement at the unknown point, thereby greatly reducing the cost. Moreover, the method can achieve a scheme of perpetually installing the spatial positioning device on to-be-measured equipment at low cost, so there is no need to carry out the manual placement and adjustment of the spatial positioning device on the to-be-measured equipment, and the to-be-measured equipment is prevented from damaging a person.
