Description

technical field [0001] The invention belongs to the technical field of mine wireless monitoring and wireless mine rescue, and in particular relates to a high-definition video collection and processing system and a collection and processing method in an underground dark environment. Background technique [0002] At present, in the field of mine monitoring, low-illuminance high-definition cameras for mines are widely used, and the existing video acquisition and processing devices all adopt the combined technical scheme of CCD sensor + DSP controller. The combination of CCD sensor and DSP controller achieves different imaging effects, and at the same time, it is equipped with optical fiber and other wired methods to transmit the collected signals. Therefore, most of the existing video acquisition and processing devices have the following limitations: high power consumption, inconvenient portability, no audio communication, and most cameras cannot work in a completely dark envir...

AI Technical Summary

Problems solved by technology

Therefore, most of the existing video acquisition and processing devices have the following limitations: high power consumption, inconvenient portability, no audio communication, and most cameras cannot work in a completely dark environment, that is, 0Lx illuminance, even if they can reach 0Lx illuminance The product is also equipped with an infrared auxiliary lighting device, which further increases power consumption; at the same time, the existing video acquisition and processing device is only suitable for the mine monitoring field, not suitable for the mine rescue process

The ARM processor has powerful processing functions, fast processing speed, rich on-chip peripherals, and various interfaces, and is suitable for various embedded systems; while the existing DSP controller has relatively large power consumption compared with the ARM controller. On-chip peripherals are limited, and the peripheral circuits are relatively complex, which restricts the area of ​​the circuit board
