In photography, angle of view (AOV) describes the angular extent of a given scene that is imaged by a camera. It is used interchangeably with the more general term field of view. It is important to distinguish the angle of view from the angle of coverage, which describes the angle range that a lens can image. Typically the image circle produced by a lens is large enough to cover the film or sensor completely, possibly including some vignetting toward the edge. If the angle of coverage of the lens does not fill the sensor, the image circle will be visible, typically with strong vignetting toward the edge, and the effective angle of view will be limited to the angle of coverage.

Compact thermal aiming sight

InactiveUS20140264020A1Television system detailsSighting devicesDisplay deviceAngle of view

A sight attachable to a weapon and comprising an objective lens, an image display, and a digital reticle. The objective lens focuses infrared light received from a scene onto a thermal imager, which is comprised of a focal plane array that detects infrared radiation in the scene focused by the lens. The image display is in signal communication with the thermal imager and provides an image of the received infrared light from the scene. The image rendered by the display is visible to the user. The digital reticle is rendered on the display and provides an aim point of the weapon upon a target in the scene. The image of the scene and superimposed reticle are directly viewable by a user with the aim point of the weapon upon the target being maintained constant over a range of viewing angles that depart from a viewing angle perpendicular to the display.

The invention discloses a camera jelly effect detection method and system based on artificial intelligence, and the method comprises the steps: obtaining three-dimensional point cloud data and RGB images of the same visual angle and range, and obtaining a depth image according to the three-dimensional point cloud data; dividing the three-dimensional point cloud data into a plurality of sub-regions, and determining each candidate region I according to the sub-regions; finding out a depth region corresponding to the candidate region I in the depth image, and screening out a candidate region II from each depth region; dividing the depth image into M sub-block regions, and dividing the RGB image into the same sub-block regions; calculating a total jelly effect quantitative index value according to the corresponding sub-block regions in the RGB image and the depth image; and finally obtaining the jelly effect severity of the RGB image. According to the invention, the three-dimensional point cloud data and the RGB image are compared and analyzed to obtain an accurate and quantized jelly effect index, so that a reference basis is provided for the surveying and mapping process of the unmanned aerial vehicle, and the jelly effect judgment result of the image is more accurate.
