| Summary: | For problems of large size of existing panoramic image acquisition devices which did not apply to coal mine underground and collected image with uneven illumination caused by pointolite in the devices, a panoramic image acquisition system in coal mine underground was designed. Synchronous control process of image acquisition of the system was introduced in detail as well as design schemes of key hardware including intrinsically safe type LED lighting device, intrinsically safe type panoramic image acquisition device, intelligent vehicle loaded mileage recorder and image acquisition synchronization controller, etc. The test result shows that the system can quickly and conveniently acquire panoramic image of coal mine underground with good image quality.
