Visual identification method for existence state of tools in tool cabinet

The invention discloses a visual identification method for the existence state of tools in a tool cabinet. The method comprises the following steps: acquiring an image in a fisheye camera video; correcting the original image, and cutting the corrected original image to obtain a to-be-recognized image; reading the calibration position, and cutting the tool from the to-be-recognized image; comparing the real-time state of the tool with the standard state by using two recognition algorithms, and integrating results; and sending the display effect to a front-end interface according to the integrated recognition result. According to the method, the work of three-tool counting in a traditional manual mode is replaced, the low-efficiency mode of manual tool counting is avoided, and the lean management requirements of tools in the fields of aviation, aerospace, ships, railways, electric power and the like can be met. 本申请公开了一种工具柜中工具存在状态的视觉识别方法，包括获取鱼眼相机视频中的图像；对原图进行矫正，矫正后切割获得待识别图像；读取标定位置，并将工具从待识别图像中切割出来；利用两种识别算法对工具实时状态与
