Embodiment
Embodiment: as a kind of embodiment of the present utility model, a kind of tunnel cable clamping apparatus pick-up unit as shown in Figure 1 and Figure 2, comprise engineering truck, described engineering truck is provided with The Cloud Terrace, described The Cloud Terrace is provided with imaging device, LED light source and light source controller, on described engineering truck, also regulate the drive unit of The Cloud Terrace height and angle, logical adjustment The Cloud Terrace height and angle realize the adjustment of adjusting imaging device shooting angle, and connect the control system of imaging device, light source controller, drive unit; Described control system comprises drive control module, processing module, storage module, human-computer interaction module and power module, the processing module electrical connection respectively of described drive control module, storage module, human-computer interaction module, power module, described drive control module is electrically connected with light source controller, drive unit, and described imaging device signal output part is communicated with processing module signal input part.
Described imaging device comprises camera and camera lens, described camera adopts the line scan camera of resolution higher than 2K, the region that is approximately 1200mm fabric width according to the observed cable part of practical data, cable clamping apparatus is 120mmx120mm x120mm, can meet testing requirement according to accuracy of detection 0.6mm.Because operating distance is 3 meters～4 meters; so whole imaging system is mainly by the line scan camera of 2K resolution; the camera lens that coordinates focal length to grow obtains good optical resolution; windage during due to locomotive high-speed cruising; camera is provided with PC protection cabinet outward, the work of the stable guarantee of the built-in ups power of described cabinet control system.
Described camera lens is telephoto lens, when camera lens is selected, need, in conjunction with its MTF parameter, select the camera lens that throughput is high, optical distortion is little.Because measured object distance is 3～4 meters, should use the larger optical lens of the depth of field, the slight jitter of imaging device is had to good tolerance; Lens aperture is adjustable, and illumination system requirements is had to good adjustable degree.Not enough is to design, to process at the aspect such as mechanical adjustment, image distortion correction, the lens parameters maximum ring that the present embodiment is selected: F1.8, minimum aperture: F16, aperture blades number: 7, focusing are recently from 0.8m, maximum amplification times yield: 0.124 times, angular field of view: 28 30 points of degree (DX forms: 18 50 points of degree).
Described LED light source has two components to arrange up and down, and be electrically connected with light source controller respectively, because detected material place ambient light illumination is extremely low, background is concrete material, and that line is swept the time shutter of camera is very short, and high power light source cannot be realized stroboscopic, in order to meet the object of artificial observation and image algorithm automatic decision, the stereoscopic features of jig need be highlighted, and form sharp contrast with background, and do one's utmost to evade form shade (can cause erroneous judgement to algorithm), therefore need to adopt the high-power projection light source of two cover custom-mades, each a set of up and down, become low-angle to place with camera lens optical axis, and front light source is slightly stronger than side, in addition, due to the high power light source in the application of rolling stock outside, in outer package design, should consider water proof and dust proof and heat radiation, the singularity of simultaneously sweeping camera imaging in view of line, consider human assistance convenience, the auxiliary aiming of laser point light source should be set.
