Cave detection device based on binocular stereo omnidirectional vision sensor

Abstract

The invention relates to a cave detection device based on a binocular stereo omnidirectional vision sensor, which comprises a cave detector immersed in a cave to be detected and a portable microprocessor arranged in the edge of a cave entrance; geological feature video information, temperature and humidity information and oxygen concentration information inside the cave are transmitted to the portable microprocessor through a wireless transmission mode; the cave detector comprises two omnidirectional vision sensors with same imaging parameters and a microprocessor for compressing and transmitting images of the two omnidirectional vision sensors to form the binocular stereo omnidirectional vision sensor; and the portable microprocessor obtains the oxygen content, the temperature and humidity and other environment data of the cave by the wireless video mode and integrates the detection of the geological feature environment and the biological living environment of the cave together. The cave detection device can transmit the ambient panoramic shape image, the oxygen concentration, the temperature and humidity and other environmental information of the cave to an observer in the cave entrance by the video mode and has good reliability.

Description

technical field [0001] The invention belongs to the application of optical technology, computer vision technology, wireless communication technology and embedded system in cave detection. Background technique [0002] According to the definition of the International Association of Speleology, a cave is a natural underground space that people can enter and exit. According to the surrounding rocks of caves, they can be divided into carbonate caves, gypsum caves, conglomerate caves, basalt caves, sandstone caves, glacier caves, etc., but the caves formed by karstification are the most widely distributed, largest in number and largest in scale on the earth. . [0003] Cave exploration refers to sports or scientific research activities such as the discovery, exploration, travel, and investigation of caves by cavers. Caving is not only a challenging and exciting sport, it is also a scientific activity. It requires participants not only to have abundant physical strength and sen...
