Spatial position regulation method

The invention discloses a spatial position regulation method, comprising the following steps: regulating levelness, i.e., regulating a radiation source body, a workpiece body and a detector body to be level, and keep the heights of the radiation source body, the workpiece body and the detector body to be the same; regulating parallelism, i.e., regulating the radiation source body and the detector body so that both keep parallel with the workpiece body; focusing, i.e., aligning focuses of a radiation source and a detector body; the step of regulating levelness comprises: respectively detecting the levelness of each of the radiation source body, the workpiece body and the detector body by means of an inclinometer, and transmitting levelness detection signals to a controller; receiving the levelness detection signals by the controller, processing the received levelness detection signals, and sending corresponding commands to drivers; driving a plurality of rise and fall execution mechanisms on the radiation source body, the workpiece body and the detector body by the drivers according to the received commands, and regulating the rise and fall of the respective bodies. The spatial position regulation method effectively solves the problems that equipment cannot be automatically regulated during industrial CT detection, and the like.
