Embodiment 1
[0082] Such as figure 1 As shown, a method for inspecting the wearing of safety helmets by construction site personnel includes the following steps:
[0083] Step 1: Determine whether the current time point is in the first time period or the second time period. If the current time point is in the first time period, initialize the camera adjustment parameters to the first parameter state. If the current time point is in the second time period, set the camera adjustment parameters to It is initialized to the second parameter state. The first period is the inspection period for the camera to capture on-site pictures of personnel wearing helmets. The second period is the dormancy period for the camera to perform ordinary security monitoring. The first parameter state includes the camera for automatic inspection. The start and end point positions, lens multiples, each rotation angle, rotation direction and the parameter value of the camera elevation angle during inspection. The sec...

The invention discloses a construction site personnel safety helmet wearing condition inspection method and system, belongs to the field of image recognition, and aims at the problems in the prior artthat a safety helmet wearing recognition method is complex, and omission exists in the inspection process. According to the construction site personnel safety helmet wearing condition inspection method and system, the system comprises an initialization module, a progress judgment unit, a human body recognition unit, a micro inspection unit, a safety helmet recognition unit, a face recognition unit and an information processing and displaying unit. The initialization module is used for initializing the camera; the progress judgment unit monitors the inspection progress; the human body recognition unit and the micro-inspection unit recognize and detect the safety helmet wearing condition of personnel, and the information processing and displaying unit receives and displays the information of personnel without safety helmets. The inspection detection speed is optimized, the required computer computing power is reduced, inspection omission is avoided and the personnel without safety helmets can be found and identified in time.
Description
technical field [0001] The invention relates to the field of image recognition, and more specifically, to a method and system for inspecting the wearing condition of safety helmets of construction site personnel. Background technique [0002] In recent years, with the development of artificial intelligence technology, image recognition technology in computer vision has obtained a large number of landing applications, such as text recognition in pictures of various product manuals, recognition of various abnormal objects in medical CT scans, weather Recognition of various satellite cloud images in the forecast, face recognition, human body key point recognition, etc. Image recognition technology has been widely used in people's daily life and management decision-making. [0003] In the construction site, ensuring the safe production of operators has always been one of the situations that the national policy emphasizes, and construction companies must ensure the implementatio...
