Problems solved by technology

However, the current industrial or medical endoscopes are finalized by shooting a video once, and the light field acquisition is not sufficient, and cannot be automatically focused, so that the imaging is blurred, the depth of the detected object and the size of the defect outline of the detected object are not clear. prone to misjudgment or misjudgment

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the drawings and embodiments.

[0030] in figure 1 In the case, the display module is built in the housing, the CCD chip (1 / 3 color camera), the eyepiece cover and eyepiece, the light field video camera, etc. form the light field imaging processing module, and the light beam, the light cone, and the image transmission fiber constitute the light field. The field transmission module, objective lens, protective glass, etc. constitute the endoscopic probe module, and each module is connected at one time. The optical fiber is placed in the hand-held hose of the searchlight illumination light source. The endoscope probe is at one end of the hand-held hose of the searchlight illumination light source. The built-in power supply is used. When the probe goes deep into the object to be detected, the scene is transmitted to the light field endoscope through the optical fiber. The light field endoscope presents a...

Abstract

The invention provides an endoscopic method for a light field video camera. The endoscopic method comprises the steps that core parts of industrial or medical endoscopic equipment are replaced by the light field video camera, and the field video camera is used for shooting first and then completing endoscopic work by using the focus function. In the later period, focus observation of anew visual angles is conducted on a video, every corner in a scene from the endoscopic video is restored in a high definition mode, and a user can observe in any visual angles. Meanwhile, under the condition that the problem that an endoscopic probe goes deep into a detected object so that the endoscopic probe can not move is solved, the software of the light field video camera is used for achieving refocusing by using the focus function, every corner is displayed clearly, and the purpose that in the process of operations and the like, under the condition that the endoscopic probe is not moved any more, the visual angles are focused and changed by the software, and all directions in the endoscopic scene are seen clearly is achieved. According to the endoscopic method for the light field video camera, the light field video camera is added in the field of industrial and medical endoscopes, the endoscopic equipment can be made to completely collect light fields, imaging in later period is made to be more clear and accurate, and files can be compressed and stored.

Description

Technical field [0001] The present invention relates to a product combining an endoscope and a light field video camera, in particular to an endoscope method of a light field video camera, in particular, it can solve the problem of unclear focus and blurred imaging of ordinary endoscopes, and observation from a forward projection angle. Observe small objects with a certain spatial structure. Under the conditions of high resolution and large numerical aperture, the depth of field is very small and it is easy to lose the target. The video will be fixed in one shot. This endoscopic video is shot multiple times at one time and changes the angle of view to observe clearly from all angles. Background technique [0002] In traditional endoscopes, to obtain a large depth of field, it is necessary to reduce the aperture, so the number of photons entered in each exposure is limited, the signal-to-noise ratio is reduced, and noise appears; in order to balance the signal-to-noise ratio, a la...
