Abstract

The invention discloses a front and rear binocular position and attitude optical measurement structure. The structure comprises a collimation light beam (1) and a frame (9), wherein a front optical sensor (3) and a rear optical sensor (7) are arranged in the frame (9) along the incident direction of the collimation light beam (1), the frame (9) is further internally provided with a beam splitter (2), a first reflector (4), a second reflector (5) perpendicular to the first reflector (4) and a third reflector (6) which is parallel to the second reflector (5) and is between the front optical sensor (3) and the rear optical sensor (7), and photosensitive surfaces of the front optical sensor (3) and the rear optical sensor (7) are parallel to the axis of a to-be-measured object. The invention further discloses a front and rear binocular position and attitude optical measurement method. The front and rear binocular position and attitude optical measurement structure is advantaged in that narrow long hole position and attitude measurement is achieved.

Description

technical field [0001] The invention belongs to the technical field of optical image measurement for shape and position measurement of manufactured parts, and more specifically relates to a structure and method for optical measurement of position and posture with front and rear dual purposes. Background technique [0002] Optical image measurement technology, that is, visual measurement and positioning technology, uses the image captured by the camera as the information carrier, extracts the useful information in the image through computer technology, and then analyzes and summarizes the information to obtain the measurement result, which has all-round rapid measurement and positioning , high precision and strong real-time characteristics, so it is widely used in various measurement tasks. [0003] Existing studies have shown that when the relative inclination angle between the journal and the bushing of a hydraulic radial bearing increases from 0 to 0.0002 radians, the perf...
