Problems solved by technology
This method is not only inefficient, but also has strict requirements on testers, which requires both care and patience, and also increases labor costs
At the same time, in high-speed industrial applications, the pulse width and frequency of the trigger pulse are ever-changing, and manual testing and verification cannot meet the requirements.

The present invention discloses a test parameter test method, device and storage medium for industrial cameras. This method includes: the first collection process of the two industrial cameras to be tested, and set the first shooting parameters corresponding to the two industrial cameras.; After controlling the two industrial cameras in the first collection process based on the first shooting parameters, the first collection process is taken to close the first collection process; the second collection process of the two industrial cameras is started, and the two to be tested are set to be tested.The second shooting parameters corresponding to the industrial camera; Among them, the first shooting parameters have a low -gain mode, and the second shooting parameter has a high -gain mode; control the two industrial cameras in the second collection process based on the second shooting parameter.After the number of photos, turn off the second collection process; whether the first number of photos and the second number of photos test the industrial camera is correct.Therefore, the implementation example of this application can accurately measure the shutter time of the industrial camera or the effective time of the gain modification.
Description
technical field [0001] The invention relates to the technical field of machine vision, in particular to a method, device and storage medium for testing shooting parameters of an industrial camera. Background technique [0002] With the development of industrial vision, industrial cameras are used in more and more scenes. High dynamic range (HDR) functions are often used for highly reflective workpieces in industrial scenes. If a complex HDR function is designed, many The acquisition of different exposures of a photo and the adjustment of the beat require the modification of parameters such as external control shutter time or gain. If the requirements for the beat are very high, then the external modification of the shutter time or the effective time of the gain needs to be accurately measured. [0003] In the prior art, the methods and means for measuring the externally modified shutter time or the effective time of the gain of the industrial camera mainly rely on manual te...
