Visible light accurate detection system for electric unmanned helicopter

Abstract

The invention discloses a visible light accurate detection system for an electric unmanned helicopter. The visible light accurate detection system comprises a camera, a pinhole camera and a wide-angle camera, wherein the camera is firmly arranged at the position through a fixing device, the camera right faces a camera eyepiece of the electric unmanned helicopter and is attached to the camera eyepiece of the electric unmanned helicopter, the fixing device comprises an inverse-L-shaped support, a threaded boss is arranged on the upper portion of the horizontal part of the support, and the support is fixedly connected with an external flash light slot located above the camera of the electric unmanned helicopter through a nut screwed on the threaded boss; a portion, opposite to the center of the camera eyepiece of the electric unmanned helicopter, of the vertical part of the support is fixedly provided with the camera through a fixing piece, the pinhole camera is used for detecting the fuel quantity and located on the front portion of an oil tank of the helicopter, and the wide-angle camera is arranged below a digital single lens reflex of the electric unmanned helicopter. The three cameras collect three sets of image signals through a video segmentation processor in a multifunctional control box located on a cradle head, the three sets of image signals are transmitted to a display device in a ground station measurement and control vehicle through an image transmission controller, and then the display device displays the three sets of video images at the same time.

Description

technical field [0001] The invention relates to an electric unmanned helicopter visible light precise detection system. Background technique [0002] With the development of the power inspection industry, the inspection equipment has also been greatly improved. As a new type of power inspection equipment newly developed in recent years, the electric inspection unmanned helicopter has many other advantages such as portability, flexibility, and height. Advantages that detection tools do not have. The power inspection unmanned helicopter relies on the onboard visible light detection equipment to take pictures of the tower. The core component of the airborne visible light detection equipment is a SLR camera. The quality of shooting is the most important indicator of the success of inspection work. Later line inspection personnel need to rely on the inspection pictures taken to analyze the safety of line towers. [0003] However, the current power inspection unmanned helicopter...

Problems solved by technology

[0003] However, the current power inspection unmanned helicopter visible light detection system generally uses a camera installed on the upper or lower part of the unmanned aerial vehicle's gimbal SLR camera, and the image captured by the camera is transmitted to the display screen in the ground station measurement and control vehicle in real time through the image transmission system. The distance between the camera and the eyepiece of the camera is too far, resulting in the real-time shooting picture range transmitted to the measurement and control vehicle is too large, which is not the fine picture range that the camera can really shoot. Close-up shots of the details and important parts of the line towers will eventually lead to a large number of pictures that are not actually required for the detailed pictures of the line towers, and even many useless pictures caused by angle deviations, making it difficult to screen and analyze later pictures

Once the pictures taken do not have the exact details of the towers that are actually required, it will directly lead to the
