Embodiment Construction

[0030] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0031] The specific application scenario of the present invention is: an exposure control scenario for an image acquisition device, especially an image acquisition scenario including a sky area and a non-sky area. When there is a sky area in the image to be collected, because the sky area is too bright, and the non-sky area is dark, when the exposure control is performed with the exist...

Abstract

The present invention provides an exposure control method, a device, and a movable platform. The method acquires an image collected by an image acquisition device, with the image including a first image area and a second image area, the first image area being a non-sky area and the second image area being a sky area; then extracting the first image area in the image; according to the brightness ofthe first image area and the preset target brightness, adjusting exposure parameters of the image acquisition device. The technical solution provided by the embodiment of the present invention can solve the problem of improper exposure easily caused by the existing exposure control method to a certain extent, and improve the image quality.

Description

technical field [0001] The present invention relates to image processing technology, in particular to an exposure control method, device and movable platform. Background technique [0002] Computer vision uses image acquisition devices and computers instead of human eyes to identify, track and measure targets. In the prior art, in the process of image acquisition, the average brightness value of the whole image area is used to realize the exposure control. However, when there are some areas with high brightness in the collected image, for example, the image containing the daytime sky, since there are some areas with high brightness in the image, when the exposure control is realized by the average brightness of the entire image area, It is easy to cause the problem of improper exposure, which makes the image overexposed or underexposed, and the image quality is poor, resulting in poor calculation effect of computer vision based on the image.
