Embodiment Construction
[0059] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0060] Such as figure 1 As shown, the present invention proposes a method for detection and positioning of strip-shaped underground targets, and the specific steps are as follows:
[0061] (1) The thermal radiation field of the simulated mountain background is established on the mountain where the strip-shaped underground target is located. This experiment established a mountain model and a strip-shaped target model. According to thermophysics, the temperature of the mountain is relatively constant, and the temperature of the strip-shaped underground target is higher or lower than the relativel...

The invention discloses a detecting and positioning method for a strip-shaped underground object. The detecting and positioning method comprises the steps of (1), establishing a simulated mountain background heat radiation field in which the strip-shaped underground object exists; (2) performing linear mapping between the simulated mountain background heat radiation field and a mountain infrared remote sensing image in which the object exists, thereby obtaining a mountain background heat radiation model; and (3) by means of the mountain background heat radiation model obtained in the step (2), filtering the simulated mountain background heat radiation from the mountain infrared remote sensing image in which the object exists, and obtaining a strip-shaped underground object information field. The detecting and positioning method settles problems of only shallow-layer object detection and positioning and low identification rate for the strip-shaped underground object in prior art. In a distorted ultra-weak signal of the strip-shaped underground target after interferences of the mountain and environment heat radiation, the mountain background information field is filtered and the strip-shaped underground object is obtained. The detecting and positioning method has advantages of overcoming difficulty in obtaining multi-temporal infrared image and remarkably improving identification accuracy in strip-shaped underground object detection.
Description
technical field [0001] The invention belongs to the intersection field of thermophysics, physical geography, pattern recognition, remote sensing and information processing, and more specifically relates to a method for detecting and locating strip-shaped underground targets. Background technique [0002] The strip-shaped underground target is a strip-shaped three-dimensional target, including civil defense fortifications, underground rivers, underground tunnels, natural underground caverns, and so on. Tunnels in mountains play a pivotal role in civilian use, especially road tunnels and railway tunnels can pass through mountains, which not only greatly shortens the length of roads, saves the time people spend on travel, but also reduces the cost of building winding roads and railways. It requires a lot of manpower and material resources, and for cars, the safety of tunnels is far greater than that of winding mountain roads. The detection and discovery of underground rivers a...
