The invention discloses handheld elevator door lock engagement depth detection equipment and a detection method. The handheld elevator door lock engagement depth detection equipment comprises an industrial camera, an annular light source, a Raspberry Pi mainboard, a detection display screen, a power supply module and an equipment main switch, the annular light source is fixed around the industrial camera; the Raspberry Pi mainboard is fixed in the device through screws and is connected with the industrial camera, the power supply module, the detection display screen and the device main switch. According to the method, the influence of the detection environment is small, the detection precision cannot be greatly influenced by the dim elevator shaft environment, and meshing depth data have higher reliability. Distortion possibly existing in an image shot by an industrial camera is processed in real time through a related algorithm, so that deviation of the door lock meshing depth caused by the problem of angle detection of equipment is avoided, and it is guaranteed that an instrument can obtain an accurate meshing depth value when shooting at any angle. And the method is suitable for various types of elevator door locks, and the phenomenon that the door locks cannot be detected due to different types of the door locks is avoided.
本发明公开了一种手持式电梯门锁啮合深度检测设备及检测方法,包括:工业相机、环形光源、树莓派主板、检测显示屏、电源模块、设备总开关;环形光源固定在工业相机外围;树莓派主板通过螺钉固定在设备中,并分别与工业相机、电源模块、检测显示屏、设备总开关相连。本发明受检测环境的影响较小,不会因为昏暗的电梯井环境而对检测精度造成较大影响,使得啮合深度数据具有更高的可靠性。通过相关算法实时处理工业相机拍摄图像可能存在的畸变,使得设备不会因检测角度的问题而造成门锁啮合深度的偏差,保证仪器在任何角度拍摄都可以得到准确的啮合深度数值。且对多种类型电梯门锁均适用,避免了因门锁类型不同而造成无法检测的现象。
