Embodiment Construction

[0046] Because when people use digital cameras to shoot, they will encounter that the images shot in the fluorescent lamp room will appear green, the scenes shot under the indoor tungsten light will be yellowish, and the photos shot in the shadow of the sun will be yellowish. The reason for the inexplicable bluishness lies in the "white balance" setting. The collected images of the existing white balance adjustment online detection system are unstable and unfavorable for detection.

[0047] For non-professionals, the operation of camera white balance is somewhat complicated, and it cannot realize fool-like operation and cannot reduce the amount of system maintenance.

[0048] In order to solve the above problems, the present invention provides figure 1 A camera automatic white balance method based on simulated annealing algorithm is shown.

[0049]The simulated annealing algorithm is derived from the principle of solid annealing. The solid is heated to a sufficiently high te...

Abstract

The invention provides an automatic white balance method for a camera based on a simulated annealing algorithm. The basic idea of adopting the simulated annealing algorithm is to utilize a random optimization problem solution procedure and the similarity with a heat balance problem in the statistic mechanics, the automatic white balance is realized based on the simulated annealing algorithm to complete the exposure and gain regulation of the camera, and an automatic white balance of an industrial camera is realized. A collected image of an online detection system is stable and reliable, which is conducive to detection. Meanwhile, since the system adopts the automatic white balance algorithm based on the simulated annealing algorithm, the operation complexity for realizing the white balance of the system of laypeople is simplified, fool operation is realized, an automatic white balance function of the industrial camera is realized, and the system maintenance is reduced.

Description

technical field [0001] The invention relates to a camera automatic white balance method based on a simulated annealing algorithm. Background technique [0002] With the development of science and technology and the continuous introduction of new technologies, analog cameras can no longer meet the development needs of industrial modernization. For digital industrial cameras, the video signal is almost the same when it reaches the output device as it leaves the camera, which can provide higher resolution, faster frame rate, less noise and more features. Therefore, digital industrial cameras will eventually replace analog cameras in the near future and become an inevitable trend in the development of the camera industry. [0003] Industrial cameras, also commonly known as video cameras, are a key component in machine vision systems, and their most essential function is to convert optical signals into orderly electrical signals. Selecting a suitable industrial camera is an imp...
