Binocular vision measurement device for solar wing deployment locking depth detection

Abstract

The invention discloses a binocular vision measurement device for solar wing deployment locking depth detection. A laser emission device projects laser to a measurement object to form multiple light stripes on the surface of the measurement object; a visual module performs acquisition and imaging of multiline structural light to obtain two-dimensional images; a transmission module sends the two-dimensional images to a data processing module; after the data processing module finishes extraction and refinement, three-dimensional reconstruction is carried out according to calibrated CCD camera model selection, camera baseline, measurement distance, measurement range, pixel resolution, camera included angle and a relative position relation between the visual module and a projection module to obtain three-dimensional coordinates of each space point of the light stripes, the form-position relation of each element in the measurement object is calculated, and the locking depth of the measurement object is calculated and outputted.

Description

technical field [0001] The invention relates to a binocular vision measurement device, in particular to a binocular vision measurement device for detecting the deployment and locking depth of a solar wing, a ground measurement used to measure one of the key indicators of whether the solar wing can be reliably locked in orbit, The invention belongs to the technical field of precision assembly of a solar wing mechanism. Background technique [0002] In order to simulate the space environment and improve the equivalence between the ground assembly performance and on-orbit performance of the solar wing, the solar wing usually needs to be assembled and deployed under ground microgravity conditions. The key performance parameters of the solar wing deployment test are the most important references to measure the technical status of the solar wing. The accuracy and effectiveness of these parameter measurements are the basic conditions for determining whether the final technical indi...

Problems solved by technology

[0003] At present, the locking depth is directly measured with a vernier caliper. Due to the large size of the solar wing, the rigidity is weak after deployment. This contact measurement method will cause the solar wing to shake slightly, which not only affects the accuracy of the measurement, but may also damage the solar wing. Secondly, during the test, due to the small diameter of the locking column, and the measurement of the vernier caliper is a point contact, it is difficult to measure at the same point each time, resulting in different measurement results each time and a large error; at the same time, Due to the small reference plane, the vernier caliper cannot accurately measure in the direction perpendicular to the reference plane, which will also cause errors; in addition, the solar wing hinges are divided into upper and lower hinges. When measuring the upper hinge, the inspector needs to go back and forth on the lift truck Moving, working at heights for a long time, there are potential safety hazards of measuring tools slipping and bumping into the solar wing
