Problems solved by technology

However, virtual reality endoscopes need to wear special stereo vision equipment, such as stereo vision helmets, glasses, etc., which cannot accurately perform three-dimensional measurement, and the price is very expensive
The optical endoscope is a stereo vision measurement system composed of two endoscopes, and it is necessary to use precise motion control devices or structured light devices to reconstruct three sets of information, which is very costly

Embodiment Construction

[0034] figure 1 A detailed structure of an endoscope system in an embodiment is shown, and the endoscope system includes an image acquisition device 10 , a controller 30 and an image processing device 50 .

[0035] combined reference figure 2 , the image acquisition device 10 is used to capture video images, and includes a main camera 101 and a sub-camera 103 , the resolution of the main camera 101 is higher than that of the sub-camera 103 . In this embodiment, the image acquisition device 10 is placed at the front end of the endoscope system and integrates a main camera 101 and a sub-camera 103 . The resolution of the main camera 101 is high, and the resolution of the sub-camera 103 is low. For example, the model of the main camera 101 is 640×480 pixels, 30 frames per second, and a diameter of about 4.5 mm; the model of the secondary camera 103 is 320×240 pixels, 30 frames per second, and a diameter of about 2.5 mm. Compared with the traditional single-camera endoscope sys...

Abstract

The invention relates to an endoscope system which is characterized by at least comprising an image acquisition device, a controller and an image processing device, wherein the image acquisition device is used for shooting a video image and comprises a main camera head and an auxiliary camera head, and the resolution of the main camera head is higher than that of the auxiliary camera head; the controller is used for controlling opening of the main camera head and the auxiliary camera head and transmitting the video image; and the image processing device is used for getting points to be measured on the video image according to a user command and performing calculation on the video image for getting three-dimensional information of the points to be measured in the video image. As for the endoscope system and a measurement method using the endoscope system, the main camera head and the auxiliary camera head are arranged in the image acquisition device, in order to get the three-dimensional information of the points to be measured, the main camera head and the auxiliary camera head are opened for measurement; and by combining the main camera head with the auxiliary camera head, the cost of the endoscope system is greatly reduced and the volume of the image acquisition device is reduced.

Description

【Technical field】 [0001] The invention relates to computer vision technology, in particular to an endoscope system and a measuring method using the endoscope system. 【Background technique】 [0002] Endoscopes are widely used in various fields due to their advantages of non-destructive detection of tiny objects and observation of places that people cannot reach, for example, the detection of walls in the construction industry, and the detection of walls in the oil and gas industry Endoscopes are widely used in the detection of internal conditions in pipelines, in the detection of engine maintenance in the automotive industry, and in the detection of explosives in the security field. [0003] During the development of endoscopes, simple two-dimensional images cannot provide enough information, so endoscopes that can provide three-dimensional information develop rapidly. [0004] According to the working principle, endoscopes that can provide three-dimensional information are ...
