The invention relates to a muzzle position identification method and system based on infrared scattering signals, and belongs to the technical field of muzzle identification. The method comprises the following steps: acquiring a target infrared image and a target active infrared image; calculating to obtain an enhanced target infrared image and an enhanced target active infrared image according to the target infrared image and the target active infrared image, and calculating to obtain an active infrared recognition area according to the enhanced target infrared image and the enhanced target active infrared image; calculating a shooting area center point according to the active infrared identification area, collecting target image data, preprocessing and identifying the target image data to obtain a target lamp identification result, and calculating a target lamp pixel center point; a pixel point distance threshold value is preset, a target lamp pixel center point is determined according to the pixel point distance threshold value, the shooting area center point and the target lamp pixel center point, and the actual space coordinates of the target lamp are calculated according to the target lamp pixel center point. The muzzle position identification is realized through the infrared scattering signal.

The application discloses a code updating method and device of firmware and electronic equipment. The method comprises the following steps: obtaining a target code package from a first cache area, wherein the first cache area is an area obtained by dividing a storage area of a controller; determining a first position of firmware original code in the first area and a second position corresponding to the first position in a second area; updating the firmware original code in the second area corresponding to the second position based on the target code package; in the case that the firmware original code in the second area is updated, switching to the second position of the second area to continue running and updating the firmware original code in the first area; and in the case that the firmware original code in the first area is updated, switching back to the first area to continue running according to the corresponding position. The application solves the technical problem of low updating reliability when updating the code of the firmware in the related art.
