[0014] In order to overcome the shortcomings of the existing CCD detectors in the field of target space position and attitude detection, the response speed is limited, the resolution is limited, the measurement circuit is complex, the requirements for the measured environment and the imaging system are high, and the PSD cannot achieve the target space position at the same time In addition to the lack of attitude measurement, the present invention provides a method for measuring the three-dimensional position of the target space, the detection distance, and the specific attitude angle of the pitch angle, yaw angle, and roll angle by using PSD, that is, the attitude can be completed while detecting the target space position Angle measurement has significant advantages such as fast detection response speed, high resolution, simple signal processing circuit, and lower requirements for the measured environment background and optical system. In addition, the present invention uses a s...
