    Publication number: 20210192761
    Abstract: An image depth estimation method includes detecting a weak texture area of a target image, calculating depths of feature points of the weak texture area, performing fitting based on the feature points to obtain a depth plane, and calculating depths of pixel points of the weak texture area based on the depth plane. The depths of feature points of the weak texture area are calculated according to coordinates of the feature points of the weak texture area in the target image and in a reference image, and a camera attitude change of one or more camera devices between capturing the target image and capturing the reference image.

  • Imaging system and method
    Patent number: 11044452
    Abstract: A method of distance measuring includes obtaining a depth map and a stereo pair of images of a scene of interest, and enhancing a precision of the depth map based on disparity values of corresponding points between the images. The images have a higher resolution than the depth map. Enhancing the precision of the depth map includes determining the disparity values by optimizing an energy function of the images and replacing low precision values of the depth map with corresponding high precision values based on the disparity values.

  • TARGET DETECTION METHOD, TARGET DETECTION APPARATUS, AND UNMANNED AERIAL VEHICLE
    Publication number: 20210118172
    Abstract: The present disclosure relates to a target detection method, including: determining a target object in a first image acquired by a first image acquisition device; estimating a position of the target object in a second image acquired by a second image acquisition device; determining whether an object at the second position is the same as the target object; and if yes, recording the second position as a position of the target object in the second image. According to the present disclosure, by estimating the position of the target object in the second image and determining whether the object at the second position is the same as the target object, a relationship between the first image acquisition device and the second image acquisition device can be established, and the second image acquisition device does not need to detect the target object in the second image again.

  • His-MBP Tagged DNA Endonuclease for Facilitated Enzyme Removal
    Publication number: 20210087550
    Abstract: Disclosed is a product and process, wherein one adds a N-terminal Histamine-Maltose Binding Protein (“MBP”) tag to endonucleases, including restriction endonucleases like Hind III, and binds the tagged fusion protein to a solid support, preferably beads, once the enzyme has digested oligonucleotides in solution, in order to arrest further digestion. Preferred beads for binding the tagged enzyme are magnetic beads, which can easily be removed from solution by binding to a support and then removing it, or can be accumulated by magnetic attraction in a particular region. More preferred are magnetic beads bound to iminodiacetic acid or nitrilotriacetic acid.

  • Thermolabile Serratia Marcescens nuclease
    Patent number: 10920202
    Abstract: Disclosed is an engineered thermolabile mutant of Serratia Marcescens Nuclease. In the same buffer as used for optimal enzyme activity, after 60° C. for 20 min, while the wild type retained 12.5% activity, the thermolabile mutant R146D/D156R/D229R/D245R (SEQ ID NO: 12, without the first 21 amino acids, which are a signal peptide) retained only 0.39% activity. Heat inactivation of the mutant, when it is used for protein purification, can be used after a period when substantial DNA in a protein has been degraded, but before unwanted degradation takes place.
