The invention provides a method for extracting an elevation control point through assistance of satellite laser altimetry data. The method is characterized in that an actual measurement waveform and a simulation observation waveform are taken as data processing objects; and by grouping the actual measurement waveform and the simulation observation waveform and considering the distance between two waveforms in the direction of the time axis and the similarity between the waveforms, through the combination of a remote sensing geometric model, registration of light spots and the topography and extraction of the elevation control point are achieved. The method comprises following steps of (1) initially refining a high-mark stereo image or an InSAR orientation parameter; (2) generating the high-mark stereo image or an InSAR DSM; (3) dividing actual measurement laser altimetry data groups; (4) extracting waveforms of the actual measurement groups; (5) searching targets and designing simulation observation; (6) carrying out simulation observation on the DSM to acquire the waveform of each simulation observation group; (7) matching the actual measurement group with the whole waveform of each simulation observation group; (8) carrying out registration on the light spot positions and the DSM plane positions; (9) matching the actual measurement group with corresponding waveform of each measurement station of the optimal simulation observation group; (10) extracting the DSM elevation system difference and the elevation control point of each light spot region; (11) extracting the elevation control point of an image; and (12) carrying out DSM elevation refinement, sensor calibration, laser altimetry and combined processing of image remote sensing data. According to the invention, registration of spatial targets of satellite laser altimetry data and satellite remote sensing data of different topographies, and extraction of the elevation control point can be achieved and spatial association can be established for combined processing of the satellite laser altimetry data and the remote sensing data.

The invention relates to a torsion experiment testing device under hot vacuum environment. The torsion experiment testing device under the hot vacuum environment comprises an adjusting machine base, an observation group, a poking rod device, a connection spline and a hot vacuum box. The adjusting machine base and the poking rod device are installed in the hot vacuum box. A part to be tested is installed on the adjusting machine base. The output shaft of the part to be tested is connected with a sealed transmission shaft of a magnetofluid through the connection spline. The sealed transmission shaft of the magnetofluid penetrates through the hot vacuum box and is led out of the box. The connection spline is connected with the poking rod device. The observation group is arranged on a box wall of the hot vacuum box. According to the torsion experiment testing device under the hot vacuum environment, the observation group is used for observing and recording the position of the output shaft of the part to be tested. In the temperature variation process of the hot vacuum box, the poking rod device is controlled to disconnect the output shaft of the part to be tested and the sealed transmission shaft of the magnetofluid. After the temperature is stable, the adjusting machine base is used for adjusting the spatial position of the part to be tested in a hot vacuum tank, the output shaft of the part to be tested is connected with the sealed transmission shaft of the magnetofluid again and a follow-up test is carried out. Affection on the test by deformation of the part to be tested in the hot vacuum test is effectively avoided, the operation is easy and the testing precision is high.
