  • Patent number: 11164293
    Abstract: A level of detail-transformation adaptive enhancement method for image contrast includes: dividing a remote sensing image into a plurality images of different levels of detail, the lowest level of detail defined as L and the highest level of detail defined as H, and gradually transforming an image Imagei of an arbitrary level of detail i between the image ImageH of the highest level of detail H and the image ImageL of the lowest level of detail L from ImageL to ImageH through the following equation: Imagei=Ri×ImageH+(1?Ri)×ImageL. The image ImageH of the highest level of detail H is an image ImageACE produced with adaptive contrast enhancement processing, or an image produced with a contrast enhancement method such as Gaussian or histogram equalization; the image ImageL of the lowest level of detail L is an image ImageLCE produced by common linear contrast enhancement.

  • Publication number: 20210173053
    Abstract: A distance measuring device includes a pulsed laser source, a light receiving unit and a computing module. The pulsed laser source emits a laser pulse to a target in accordance with a predetermined period. The light receiving unit has a photon receiving type of light receiving element that receives incident light and outputs a binary pulse, and the binary pulse is used to indicate whether a photon receiving event occurs. The computing module is configured to receive the binary pulse and determine whether an inter-period coincidence event occurs, and the inter-period coincidence event is defined by detecting a plurality of photon receiving events exceeding a predetermined count, on relative positions in a predetermined period number of the predetermined periods. If the calculation module determines that the inter-period coincidence event occurs, a distance of the target is calculated according to time information related to the inter-period coincidence event.
