  • Publication number: 20210012110
    Abstract: An object detection apparatus includes a boundary box decision circuit and a processing circuit. The boundary box decision circuit receives lens configuration information of a lens, and refers to the lens configuration information to determine a bounding box distribution of bounding boxes that are assigned to different detection distances with respect to the lens for detection of a target object. The processing circuit receives a captured image that is derived from an output of an image capture device using the lens, and performs object detection upon the captured image according to the bounding box distribution of the bounding boxes.

  • Publication number: 20200398271
    Abstract: A sample carrier device including a single substrate, a penetration structure and a fixing structure is provided. The penetration structure is formed on a side of the substrate. The penetration structure has a fluid passage. The fixing structure is formed on a side of the penetration structure. The sample carrier device is divided into an end portion, an observation portion and an operation portion. The user can separate the observation portion from the end portion by operating the operation portion. After the observation portion is separated from the end portion, the user can inject the sample into the fluid passage through a port of the fluid passage exposed to the observation portion. Once the sample is carried by the fluid passage of the observation portion, the user can seal the port of the fluid passage and place the observation portion in an electron microscope device.
