Image correction method and detection device

Abstract

The present invention provides an image correction method and detection device. The method includes: determining the observation area from the first image frame in the dynamic image, and obtaining the center position of the observation area in the first image frame; Determine the first feature region that conforms to the grayscale feature; obtain the first vector according to the center position of the first feature region in the first image frame and the center position of the observation area; in the second image frame in the dynamic image, according to the grayscale feature Find the second feature area; obtain the second vector according to the center position of the second feature area in the second image frame and the center position of the observation area; and correct the observation area in the third according to the difference between the two vectors and the first vector The position in the image frame. The image correction method and detection device provided by the present invention can maintain the observation area in an appropriate position in each image frame, thereby providing good detection function and more accurate detection results.

Description

technical field [0001] The present invention relates to a calibration method and detection device, in particular to an image calibration method and detection device Background technique [0002] Medical ultrasonography is a medical imaging diagnosis technology based on ultrasound, which can reveal the size, structure and lesions of muscles and internal organs in the human body. In the application of medical ultrasonography, Doppler ultrasound has greatly improved the capabilities of medical ultrasonography. The flow of fluid in the human body or in a living body is detected by Doppler ultrasound. For example, the flow direction and velocity of blood can be measured by Doppler ultrasound, which can provide an effective detection function in cardiovascular and other related medical fields. [0003] However, the observation area of ​​the Doppler ultrasound is mainly selected by the inspector according to the images generated by the ultrasound. Tracking a specific area in cont...

Problems solved by technology

Since the observation area of ​​the Doppler ultrasound is positioned relative to the image generated by the ultrasound, the change of the ultrasound image will also change the observation area of ​​the Doppler ultrasound, thereby reducing the accuracy of the Doppler ultrasound.
