Embodiment

[0030] 1) Camera bracket

[0031] Such as figure 1 As shown in the figure, the camera bracket is to place two cameras with infrared lenses in parallel. They are fixed at both ends of a metal rod with a length of about 100cm, and the distance between the centers of the lenses of the two cameras is required to be 100cm. Each camera leads out two wires, which are a power supply wire and a communication wire. The power supply wire is further subdivided into two wires: a power wire and a ground wire; the communication wire is also subdivided into two wires: Signal and ground wires.

[0032] Establish a spatial coordinate system that meets the following requirements: the x-axis coincides with the line connecting the centers of the two lenses, and the origin O coincides with the midpoint of the line, the lens planes of the two lenses are perpendicular to the y-axis, and the camera faces the positive direction of the y-axis.

[0033] The following is the positioning principle of th...

Abstract

The invention discloses a fire hazard monitoring and positioning device and a fire hazard monitoring and positioning method, and belongs to the field of embedded computers. The device comprises a camera support, a hardware circuit and the fire hazard monitoring method. Two cameras with infrared lenses are disposed in a spatial level way and fixed on the two ends of a metallic rod, and central distance of the lenses of the two camera ranges from 80 to 120cm to form the camera support. The hardware circuit takes a digital video media processor as a core, and comprises a video signal acquisition circuit, a smog concentration acquisition and processing circuit and a network communication circuit. The fire hazard monitoring method comprises two parts, wherein the smog concentration monitoring involves periodically acquiring and processing voltage and uploading the concentration information to a server for achieving, and flame identification and positioning involves determining occurrence of fire hazard through a flame identification algorithm and further calculating the fire starting position according to the space structure of the cameras. The device and method disclosed in the invention are of great importance to the fields including smog concentration monitoring, fire hazard alarm and subsequent fire hazard situation analysis.

Description

technical field [0001] The invention belongs to the field of embedded computers, and relates to a binocular camera-based fire monitoring and positioning device and a fire monitoring and positioning method. Background technique [0002] At present, the vast majority of fire monitoring devices can only monitor the occurrence of fire, but cannot determine the physical location of the fire point. At the same time, the current flame recognition algorithm may make false detections under strong light, which brings a certain degree of blindness to fire rescue. The present invention aims to improve the accuracy of fire monitoring, provide the physical location of the specific fire point, provide data support for fire rescue and provide effective data records for subsequent fire analysis. [0003] Since processing an image with a large amount of information requires correspondingly more processor resources, reducing unnecessary image information can improve system processing performan...
