Embodiment Construction

[0053] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0054] A kind of electronic image stabilization method based on shipboard equipment of the present invention, its flow process is as follows figure 1 shown. The concrete steps of this method are as follows:

[0055] (101) Original video image acquisition

[0056] Collect the video images collected by the cameras in the shipboard equipment and transmit them to the computer for post-processing.

[0057] (102) Select the reference frame image

[0058] The reference frame image selected for the first time is generally the first frame image collected by the camera after the shipboard equipment is stabilized. After that, in order to eliminate the accumulated error, the reference frame image selected for the first time needs to be updated. Specifically: when the rotation angle θ and translation (Δx, Δy) of the current frame image relative to the reference frame ...

Abstract

The invention discloses an electronic image stabilization method based on a ship-bone device, relates to the field of digital image processing and solves the problem that an existing electronic image stabilization method does not apply to the ship-bone device. The method comprises the steps of collecting original video images; selecting a reference frame image; reading a current frame image; calculating motion vectors: horizontal offset, vertical offset and a rotation angle through adoption of a motion estimation method based on an object-sky curve; filtering the motion vectors; compensating the motion vectors; and outputting a stabilized image. According to the method, according to the features of the images collected by the ship-bone device, when the motion vectors are estimated, the deficiency of the existing method is overcome, the new motion estimation method based on the object-sky curve is provided, and the image stabilization function of the ship-bone device is realized. According to the method, the translation quantity and the rotation angle of the current frame image relative to the reference frame image can be calculated rapidly and accurately, the operation quantity is low, the precision is high, the timeliness of an algorithm can be improved, the accuracy of the algorithm also can be improved, and the method has good robustness.

Description

technical field [0001] The invention relates to the technical field of digital image processing, in particular to an electronic image stabilization method based on shipboard equipment. Background technique [0002] Research on electronic image stabilization technology began in the mid-1980s. Electronic image stabilization is a new generation of image stabilization technology that integrates electronics, computer, image recognition and other technologies to directly determine and compensate the mapping relationship between frames of image sequences, aiming to eliminate random motion in video image sequences. Compared with traditional mechanical image stabilization and optical image stabilization, electronic image stabilization has the advantages of easy operation, high image stabilization accuracy, strong flexibility, small size, light weight, low energy consumption, and highly intelligent real-time processing. Using electronic image stabilization technology to achieve video...
