Embodiment Construction
[0013] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.
[0014] Such as figure 1 As shown, the present invention provides a frame rate detection method of an imaging device, comprising the following steps:
[0015] S1. Parameter setting: define the image data acquisition area, set the acquisition time and acquisition frequency C of the image data; specifically: define the image data acquisition area, set the timer running time and interrupt time interval dT, then the acquisition frequency C=1 / dT , the running time of the timer is the acquisition time;
[0016] S2. Image data acquisition and processing: including image data acquisition and storage, determination of the number of changed frames and determination of the total duration of the change of the number of frames. ...

The invention relates to a frame rate detection method for imaging equipment, which comprises the following steps: defining an image data acquisition area, and setting the acquisition duration and acquisition frequency of image data; Continuously acquiring and storing multiple frames of image data and corresponding image data acquisition moments of the image data acquisition area until all the image data and image data acquisition moments in the acquisition duration are acquired, and acquiring a total change frame number and a change frame number change total duration according to all the image data; Calculating the current detection frame rate of the imaging equipment according to the total frame number and the total change time length of the change frame number, outputting the current detection frame rate value if the current detection frame rate is smaller than the product of the acquisition frequency and the preset value of the positive number smaller than 1, completing the frame rate detection, otherwise, increasing the acquisition frequency, and restarting the acquisition. According to the method, the collection frequency is automatically adjusted, cyclic detection and judgment are carried out, on one hand, occupation of processor resources is reduced, and on the other hand, high accuracy of the finally obtained frame rate value is guaranteed.
Description
technical field [0001] The invention relates to the technical field of imaging equipment, in particular to a method for detecting the frame rate of the imaging equipment. Background technique [0002] At this stage, a large number of imaging devices play a very important role in different industries. Imaging devices in the medical field (such as CT, MRI, ultrasound, endoscopy, and fundus) provide intuitive images of organs or tissues. play an indispensable role in it. When imaging organs with obvious motion, the frame rate of the imaging device will seriously affect the imaging effect. For example: when using confocal endoscopy to observe the morphology and structure of gastric mucosal tissue cells, the higher the frame rate of the confocal endoscopy, the less motion artifacts in the resulting image, and the more images captured per unit time. More effective data can be provided, and the possibility of missed detection is smaller. When using an ultrasound imaging system t...
