Problems solved by technology

The most important step of this type of method is to match the same target in the left and right views when calculating the disparity. However, in the endoscopic scene, the texture features are weak, and the color of the background is similar to that of the lesion target, so it is very easy to cause mismatching, resulting in large error

Embodiment Construction

[0046] The present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments, and the purpose and effect of the present invention will become clearer. It should be understood that the specific embodiments described here are only used to explain the present invention and are not intended to limit the present invention.

[0047] The method for measuring and displaying the three-dimensional size of the lesion based on the binocular endoscope of the present invention uses the end point of the probe that enters the body through the instrument channel of the endoscope as the feature point to replace the point in the weak texture area of ​​the lesion, and displays the measurement result through a three-dimensional virtual ruler, such as figure 1 As shown, the method specifically includes the following steps:

[0048] S1: Probe point selection, that is, move the probe to select points according to the feature point selection speci...

Abstract

The invention discloses a focus three-dimensional size measurement and display method based on a binocular endoscope. The focus three-dimensional size measurement and display method comprises five steps of probe point selection, probe end point identification, end point binocular matching, focus three-dimensional measurement and virtual scale display. According to the method disclosed in the invention, the limitation of comparative measurement of the lesion size by using a physical scale or a virtual scale is solved, and the problem of inaccurate three-dimensional measurement result caused byeasy mismatching of a three-dimensional reconstruction measurement method in a weak texture area such as a lesion target is also solved. The method can be used for precisely measuring the three-dimensional size of a lesion, a three-dimensional virtual scale is generated to assist a doctor in judgment, operation is easy, and results are accurate.

Description

technical field [0001] The invention relates to the technical field of endoscopes, in particular to a method for measuring and displaying three-dimensional dimensions of lesions based on a binocular endoscope. Background technique [0002] In modern medical treatment, endoscope enables clinicians to discover and identify lesions and other physiological characteristics in the gastrointestinal tract, which is of positive significance for the treatment of diseases. Compared with traditional endoscopes, 3D endoscopes can provide three-dimensional information, which is more It can reflect the real situation of the scene. On the one hand, it can let the doctor feel the visual effect of the 3D picture during the operation, provide a realistic visual experience, and help the doctor to operate the endoscope more accurately. On the other hand, the 3D endoscope can integrate three-dimensional measurement Function, for some lesion targets such as polyps, accurate three-dimensional measu...
