Full Holewall Camera Portable Mapping 3D Imaging Easy Operation Underground Deep Search Mineral Detector
The full-hole wall imager is an efficient and accurate underground detection device, which is mainly used for panoramic imaging and video recording of rock formations in the borehole. Here is the relevant introduction:
1.Technical Feactres
The image resolution is high, and the video and full-hole wall information can be clearly seen on site, without shutter phenomenon and delay phenomenon;
The instrument has fast processing speed, and the fastest speed can reach 10m/min even in the case of on-site image splicing and video recording;
The illumination intensity of the probe tube is continuously adjustable, and clear imaging can be achieved for various detection objects;
The system is stable and reliable, and the all-solid-state design makes the instrument have good seismic resistance. The sealing technology based on the integrated logging system ensures the waterproof effect of the probe tube and the host;
The special fisheye image processing method repairs the nonlinear distortion of the fisheye lens and restores it to a plane columnar chart without loss;
