Fire detection method, device and equipment

Abstract

Embodiments of the present invention provide a fire detection method, device, and equipment. The method includes: acquiring a depth image and an infrared image through a TOF depth module; comparing the depth image with a preset reference depth image to obtain a first comparison result; comparing A second comparison result is obtained between the infrared image and a preset reference infrared image; and whether there is a fire is determined according to the second comparison result and a plurality of consecutive first comparison results. By comparing the depth grayscale difference corresponding to the depth image with the infrared grayscale difference corresponding to the infrared image, it is finally determined whether a fire has occurred, and further the location of the fire can be determined based on the image, so that it can quickly and accurately determine whether a fire has occurred , and can provide the staff with accurate location information and corresponding image information of the fire.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a fire detection method, device and equipment. Background technique [0002] At present, fire monitoring and detection equipment is arranged in various public places, such as schools and shopping malls. In order to find the fire in the shortest time and call the police in time when a fire occurs. [0003] In the prior art, smoke detectors are usually used for alarming. The equipment cost of this alarming device is relatively low, and it is also the most widely used alarming device in public places at present. However, some fires may be directly burned by a large fire. When the smoke detector detects smoke, the fire may have developed to a very serious level, and the fire cannot be discovered in time. Due to changes in indoor temperature and light, the existing infrared fire alarms are likely to interfere with the detection results, and are prone to misjudgments...

However, some fires may be directly burned by a large fire. When the smoke detector detects smoke, the fire may have developed to a very serious level, and the fire cannot be detected in time.

The existing infrared fire alarms, due to changes in indoor temperature and light, are likely to interfere with the detection results, and are prone to misjudgments, resulting in failure to detect fires in time
