Abstract

The invention belongs to the technical field of photoelectric measurement, and provides a measuring device and a measuring method for a distance and an attitude angle. The measuring device includes a measuring device and a target board; the measuring device includes a connecting frame, and an image sensor arranged on the connecting frame , a projection laser and an optical lens; the target plate is fixed on the object to be measured; the projection laser is used to send a laser beam to the target plate, and the target plate forms a target point measurement point after being irradiated by the laser beam; the optical lens The target point measurement point is imaged on the image sensor, and the image sensor detects the image of the target point measurement point and sends it to the processor; the processor calculates the measured object according to the detection data and sends it to the measurement device The distance and the attitude angle of the measured object. The application realizes the simultaneous and synchronous measurement of the distance and the attitude angle in the same opto-mechanical system, so that the measuring equipment has a simple structure and a small volume, and can realize long-distance non-contact measurement.

Description

technical field [0001] The invention relates to the technical field of photoelectric measurement, in particular to a measuring device and a measuring method for a distance and an attitude angle. Background technique [0002] Distance and attitude measurement is an important part of metrology science, and it has extremely important significance and functions in many fields such as aerospace, automobile manufacturing, industrial measurement, precision machining and instrument manufacturing. Due to its wide application, various research units at home and abroad have conducted a lot of research and developed a variety of measurement methods. The methods used in distance measurement mainly include: pulsed laser ranging technology, phase laser ranging technology, and binocular intersection ranging technology. Usually, when measuring distance and attitude angle at the same time, according to the measurement requirements in different environments, one or more technologies are selec...
