Problems solved by technology

Usually, in order to acquire images with afterimage special effects, the photographer needs to manually control the camera device, such as controlling exposure parameters, moving the camera device, etc., to obtain images with afterimage special effects only when certain conditions are met, which is complicated to operate. Photographers have relatively high technical requirements for shooting

Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0024] In order to reflect the dynamic effect of the target object being photographed, some images with afterimage special effects can be collected. The afterimage image has a trailing effect, which can well reflect the dynamic effect of the target object, making the image have a sense of rhythm and rhythm. Usually, when capturing images with dynamic effects such as afterimage images, there are certain requirements for the moving speed of the target object, the brightness of the envi...

Abstract

The invention discloses an image acquisition method, a control device and a movable platform. The method is used for collecting a target image through a camera device installed on a cradle head, and comprises the steps that exposure parameters of the camera device are determined, and the exposure parameters comprise exposure duration; determining rotation parameters of the cradle head, the rotation parameters including a rotation direction, a rotation angle and a rotation speed of the cradle head, the rotation speed being determined based on the exposure duration and the rotation angle; and controlling the holder to rotate based on the rotation parameters, and controlling the camera device to perform image acquisition based on the exposure parameters so as to obtain the target image. In the exposure process, the holder drives the camera device to have a certain motion speed, a target image with dynamic special effects such as ghost images can be automatically acquired, the operation issimple, and images with dynamic special effects such as ghost images can also be acquired for some static objects or objects with low motion speed.

Description

technical field [0001] The present application relates to the technical field of image acquisition, in particular, to an image acquisition method, a control device and a movable platform. Background technique [0002] In many shooting scenes, in order to reflect the dynamic effect of the target object being photographed, some images with afterimage effects can be collected to make the images more rhythmic and rhythmic. Usually, in order to acquire images with afterimage special effects, the photographer needs to manually control the camera device, such as controlling exposure parameters, moving the camera device, etc., to obtain images with afterimage special effects only when certain conditions are met, which is complicated to operate. Photographers have relatively high technical requirements for shooting. Therefore, it is necessary to provide a method with simpler operation to capture images with afterimage effects. Contents of the invention [0003] In view of this, t...
