Description
Technical field
The utility model relates to industrial technical field of imaging, and in particular to a kind of high-precision detection technique of high-speed rod.
Background technique
Due to high-speed rod to diameter, coordinate, curvature it is more demanding, in the detection of the line footpath of round stocking, cable,
Cable, optical fiber, rubber, plastics etc. are required to realize high-precision online dimension detection.And control dragger or extrusion can be passed through
The speed of machine controls the size of line footpath.Traditional measurement method realizes Measurement Algorithm using special FPGA chip, and specificity is strong
Flexibility is poor, and for different measurement demands, hardware is difficult to flexibly support.Therefore, although Traditional photovoltaic caliper can be to circle
The equipment that measured object in rolling carries out on-line real-time measuremen brings huge economic benefit for producer.But traditional photoelectricity
Calibrate that speed is slow, can not the materials such as circle to high speed measure.
Summary of the invention

Reception device includes CMOS module 3 and the telecentric lens 4 that use C interface is connect with the mainboard of CMOS module 3.Telecentricity
Optical filter is additionally provided between camera lens 4 and a word green LED light source 1.CMOS module 3 is powered by 5V circuit board.CMOS module 3
On be provided with image output interface.
One word green LED light source 1 issue perpendicular to wire rod outlet direction line-styled directional light, by optical filter by its
The removal of its light source, CMOS module 3 captures the hot spot of green LED light, after green spot passes through image signal process, by passing through image
Interface output, image extract green spot by centroid algorithm, and specific algorithm is：
As described above, although the utility model has been indicated and described referring to specific preferred embodiment, it must not
It is construed to the limitation to the utility model itself.In the spirit and scope for not departing from the utility model that appended claims define
Under the premise of, it can various changes can be made in the form and details to it.
