Safety prompting method and system for elevator operation
ActiveCN109353907AAvoid being caughtImage enhancementImage analysisControl engineeringControl theory
The invention relates to a safety prompting method and system for elevator operation. The safety prompting method comprises the following steps that a depth image of a use area of an elevator is obtained, when image information of an identification object exists in the depth image, whether the identification object is in a designated state or not is judged according to the image information, and when the identification object is not in the designated state, a car door of the elevator is in an action state or an open state, a safety prompt message indicating that the operation state of the elevator is to be noticed is sent out. In this solution, the depth image of the elevator use area is subjected to the identification and analysis treatment so that whether the identification object in theuse area of the elevator is in the designated state or not can be obtained, if the identification object is not in the designated state, when the car door of the elevator is in the action stare or the open state, the identification object can be prompted to pay attention to the operation state of the elevator, so that the attention of the identification object is concentrated on the elevator, anddangerous accidents such as clamping and misstep of the identification object are avoided.
