Embodiment 1

[0024] Such as Figures 1 to 2 Shown, a kind of image acquisition method based on high-speed camera binocular stereovision, comprises the following steps:

[0025] a. Construct the optical path;

[0026] b. Obtain blue and green images through the optical path built in step a. After the measurement starts, the data acquisition instruction sent by signal trigger 2 is decomposed into trigger signal A (3) and trigger signal B5 through signal decoder (4) , the two trigger signals respectively control the two high-speed cameras so that the data acquisition is carried out alternately in sequence, specifically: the optical path built through step a, under the action of the trigger signal A3, the high-speed camera A15 acquires the RGB image 20 and decomposes it into blue Image component 18 and green image component 19, then, under the action of trigger signal B5, high-speed camera B6 acquires RGB image 20, and can be decomposed into blue image component 18 and green image component 1...

Abstract

The invention discloses an image acquisition method based on high-speed camera binocular stereo vision. The method comprises the following steps: a, constructing a light path; b, obtaining a blue image and a green image through the light path built in the step a, and obtaining the blue image through a high-speed camera B to form an RGB image to obtain a blue image component; acquiring the green image through a high-speed camera A to form an RGB image to obtain a green image component; and c, respectively extracting the blue image component and the green image component to obtain two independent images for binocular stereo vision calculation. According to the method, the defects of an existing binocular stereoscopic vision system in the aspects of synchronous images and acquisition frequency during dynamic measurement can be overcome, two sets of binocular stereoscopic vision measurement systems triggered in sequence are formed through the technology, and the image acquisition frequencyis improved while the synchronous images are acquired.
