FIG. 1 is a schematic diagram of an application of a high-heat steel pipe length measuring device based on visual inspection.
Fig. 2 is a schematic view of a camera of a high-heat steel pipe length measuring device based on visual inspection.
Detailed Description
The length measuring device for the high heat steel pipe based on the visual inspection will be described in detail with reference to the accompanying drawings.
FIG. 1 is a schematic diagram of an application of a high-heat steel pipe length measuring device based on visual inspection. The laser scale system 100 is composed of 8 laser line emitters 110, the laser line emitters 110 are arranged at equal intervals of 1m, the arrangement direction is parallel to the furnace discharging direction of the steel pipe, the laser of the laser line emitters 110 is projected on the steel pipe, and light marks similar to scales are formed on the steel pipe. The camera 200 adjusts the focus to the position of the steel pipe in advance by manual focusing or software autofocus, and photographs the steel pipe. The camera 200 is connected with the industrial computer 300 through a network cable, the photo information is transmitted to the industrial computer 300 through the network cable, the photo is analyzed by the visual analysis software of the industrial computer 300, the scales of the area covered by the steel pipe are calculated, and the full integer is directly calculated. And for the length less than one unit, converting according to the resolution ratio and the occupied scale ratio, thereby obtaining the accurate length of the steel pipe.
The industrial computer 300 has various communication interfaces such as an industrial ethernet, a network cable, a WIFI, a cellular network, and the like, and can transmit the measured length information to a designated terminal, and in this embodiment, the measured length information is transmitted to a server of an intelligent production line, so that the subsequent process and the intelligent production allocation are facilitated.
It should be added that the number, arrangement, spacing, etc. of the laser line emitters 110 included in the laser scale system 100 in this embodiment are related to the length and measurement accuracy of the steel pipe to be measured, the arrangement of 8 laser line emitters with an equal spacing of 1m in the embodiment is only for illustration, and the arrangement and number of other laser line emitters are within the protection scope of this patent.
Fig. 2 is a schematic view of a camera of a hot steel pipe length measuring apparatus of a pipe mill based on visual inspection. Camera body 210 links to each other with high accuracy camera lens 220, realizes the shooting function to the outside scene, and light filter 230 accomplishes the filtration to the dazzling light of external hot metal at high accuracy camera lens 220 foremost, prevents to lead to length information unable analysis because overexposure, and camera lens protective sleeve 240 keeps apart camera lens and external high temperature environment in the high accuracy camera lens 220 outside, accomplishes the protection to the camera lens.
