The invention belongs to the technical field of industrial shooting, and particularly relates to an exposure delay measurement method and device and a storage medium. The method comprises the following steps: acquiring exposure time of the industrial camera; obtaining an exposure delay change interval of the industrial camera; and determining a target exposure time interval according to the exposure time and the exposure delay change interval, the target exposure time interval being a time interval in which a shutter of the industrial camera is always opened. According to the embodiment of theinvention, the method can achieve the quick and accurate measurement of the exposure delay change conditions of the industrial camera under different exposure conditions, and can determine the stabletarget exposure time interval of the industrial camera.
Description
technical field [0001] The present application belongs to the technical field of industrial photographing, and in particular relates to an exposure delay measurement method, device and storage medium. Background technique [0002] With the rapid development of industrial technology, the demand for machine vision is growing. At present, in many industrial application scenarios, high-speed "flying photography" is required. In order to avoid smear, the exposure time of industrial cameras needs to be reduced to the "microsecond" level, such as 15us. [0003] However, in the related art, there is no method for accurately measuring the change of the exposure delay of the industrial camera under different exposure conditions. [0004] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the application, and therefore may include information that does not constitute prior art kno...
