Embodiment Construction

[0044] Such as figure 1 , figure 2 , image 3 shown. The large-space visual tracking 6D measurement system includes a self-zooming tracking camera 1, which is installed on a three-dimensional rotating pan-tilt 2, and an angle code wheel 3 and an angle code wheel 4 are installed on the pan-tilt 2. It also includes an independent six-degree-of-freedom probe 5. The top of the six-degree-of-freedom probe 5 is a target ball 6. Cylindrical holes 7 are evenly arranged on the target ball 6 at the intersecting positions of the longitude and latitude at a certain angle. Three kinds of color markings 8 are placed in the hole according to the arrangement rules of the pseudo-random array code, and the three kinds of color markings 8 can be realized by three kinds of light-emitting diodes of red, yellow and blue, and three kinds of non-luminous red, yellow and blue can also be used. The object realizes. The position of the center of the cylindrical hole 7 on the surface of the target b...

Abstract

The invention discloses a large-space visual tracking six-dimensional measurement system and method. The system mainly comprises a self-zooming visual tracking camera and a color paseudorandom coding six-freedom degree measuring head. The gesture and space position coordinates of the measuring head are confirmed by utilizing the position change of a hole center with color paseudorandom coding expression on a target ball so as to realize the measurement of large-size space six-freedom degree. The system can be combined with a joint arm coordinate measuring machine to realize local high-precision measurement and positioning and can be also combined with assembly equipment of electric drilling, and the like to realize the precise assembly of large equipment.

Description

technical field [0001] The invention relates to an industrial dimension measurement system, in particular to a large-scale space precision measurement applied to an industrial site, in particular to a large-space visual tracking 6D measurement system and a measurement method. Background technique [0002] At present, with the development of my country's large-scale equipment manufacturing industry, higher and higher requirements are put forward for large-scale precision measurement technology in space. The existing space large-scale measurement system is mainly composed of the following types: (1) theodolite measurement system; (2) laser tracking measurement system; (3) digital close-range industrial photogrammetry system; (4) laser scanning measurement system; (5) ) Joint arm coordinate measuring system; (6) Indoor GPS. Most of the above measurement systems are single-point measurement, which cannot realize the measurement of six degrees of freedom. Although the laser tra...
