Curve determination method, device and equipment

Abstract

The invention provides a curve determination method, device and equipment. The method comprises the following steps: controlling a zoom lens to move to Q first position points through a zoom motor; controlling a zoom lens to stop at a first position point through a zoom motor, and controlling a focusing lens to move to a second position point matched with the first position point through a focusing motor; wherein when the focusing lens moves to the second position point, the image acquired by the camera meets the definition requirement; constructing Q coordinate points based on the Q first position points and the Q second position points; performing polynomial curve fitting on the Q coordinate points to obtain a forward zoom following curve; the forward zoom following curve represents the mapping relation between the position point of the zoom lens and the position point of the focusing lens. According to the technical scheme, the image acquired based on the zoom following curve is clear, and the image effect is good.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to a method, device and equipment for determining a curve. Background technique [0002] Cameras usually have a zoom (also called zoom) function and a focus function. For example, a camera includes a zoom motor, a focus motor, a zoom lens, and a focus lens. The zoom lens is driven by the zoom motor to move to achieve the zoom function. Driven by the focus motor The focusing lens moves to achieve the focusing function. [0003] Usually, the zoom lens and the focus lens are moved separately. When the zoom lens is driven by the zoom motor, the focus lens needs to be driven by the focus motor to move, so as to realize zoom follow. Zoom follow means that when the zoom motor controls the zoom lens to perform zoom operation, the focus motor also controls the focus lens to perform focus operation, that is, the focus motor moves together with the zoom motor.

AI Technical Summary

Problems solved by technology

[0005] In related technologies, the zoom follow curve is configured based on user experience, and all cameras are configured with the same zoom follow curve. However, due to differences in the lenses of different cameras, the zoom follow curve cannot be applied to all cameras. The image collected by following the curve is not clear and the image effect is poor

For example, when the zoom lens moves to the position point A, the position point B' matching the position point A is found through the zoom tracking curve, and the focus lens is moved to the position point B', when the zoom lens is at the position point A, And when the focusing lens is at position B', the image captured by the camera has poor clarity
