  • Publication number: 20230022933
    Abstract: A system may access an image that is captured by an imaging device and that depicts an operational scene illuminated by close-range light. The system may also access a depth map of the operational scene that includes depth data corresponding to each pixel in the image. Based on the depth map, the system may determine a far-range lighting coefficient for each pixel in the image based on a relationship between the corresponding depth data included in the depth map for that respective pixel and a target distance to a virtual light source that is to be simulated to be illuminating the operational scene. Based on the image and these far-range lighting coefficients, the system may generate a processed image depicting the operational scene as being illuminated by the virtual light source and may provide the processed image for presentation on a display screen. Corresponding systems and methods are also disclosed.

  • Patent number: 11478308
    Abstract: Methods and system perform tool tracking during minimally invasive robotic surgery. Tool states are determined. using triangulation techniques or a Bayesian filter from either or both non-endoscopically derived and endoscopically derived tool state information, or from either or both non-visually derived and visually derived tool state information. The non-endoscopically derived tool state information is derived from sensor data provided either by sensors associated with a mechanism for manipulating the tool, or sensors capable of detecting identifiable signals emanating or reflecting from the tool and indicative of its position, of external cameras viewing an end of the tool extending out of the body. The endoscopically derived tool state information is derived from image data provided by an endoscope inserted in the body so as to view the tool.

  • Patent number: 11475548
    Abstract: A lighting emulation system accesses an image that is captured by an imaging device and that depicts an operational scene illuminated by close-range light. The lighting emulation system accesses a depth map of the operational scene that includes depth data corresponding to each pixel in the image. Based on the depth map, the lighting emulation system determines a far-range lighting coefficient for each pixel in the image. Specifically, the far-range lighting coefficient for each respective pixel is determined based on the corresponding depth data included in the depth map for that respective pixel. Based on the image and the far-range lighting coefficient for each pixel in the image, the lighting emulation system generates a processed image depicting the operational scene as illuminated by far-range lighting, and provides the processed image for presentation on a display screen.

  • Publication number: 20220296317
    Abstract: A system may comprise an image capture device to capture an image of a work site. The system may also comprise a processor to determine whether a tool disposed at the work site is energized and determine a first area of the captured image of the work site, including or adjacent to an image of a portion of the tool in the captured image. The processor may also determine a second area of the captured image including a remainder of the captured image that does not include the first area. Conditioned upon determining that the tool is energized, at least one of the first area and the second area of the captured image of the work site may be processed to indicate that the tool in the first area is being energized. The image of the work site with the first area and the second area may be displayed.

  • Patent number: 11389255
    Abstract: A system may comprise an image capture device disposed to capture an image of a work site, a display, and a processor. The processor may be configured to determine whether a tool disposed at the work site is energized and determine an area of the captured image of the work site, including or adjacent to an image of a portion of the tool in the captured image, to be filtered to indicate the tool has been energized. Conditioned upon determining that the tool is energized, the processer may also filter the area of the captured image of the work site to generate a filtered area of the captured image of the work site so as to create a glowing effect on the image of the portion of the energized tool, indicating that the tool is being energized. The image of the work site with the filtered area may be displayed on the display.

  • Patent number: 11331156
    Abstract: A system includes a controller communicatively coupled to an illuminator and to a camera configured to capture a scene including tissue. The controller may change the output optical power of the illuminator from a first output optical power to a second output optical power so that a subsequently captured frame is captured by the camera from reflected light, the reflected light being light from the illuminator having the second output optical power prior to being reflected. The controller may determine that an endoscope contacted the tissue if the change of the output optical power of the illuminator results in a change of a reflected luminance that is less than a predetermined threshold, the change of the reflected luminance being a change from a first reflected luminance for the first output optical power to a second reflected luminance for the second output optical power.

  • Publication number: 20210386279
    Abstract: An illumination source may be coupled to an image capture device through a connector. A light sensor is placed downstream of the connector to measure the light received by the image capture device from the illumination source. The light sensor provides the measurement of the received light to the illumination source for closed-loop control of illumination source. The light sensor may be positioned in a camera housing to take into account light attenuation from the illumination source to the camera. The light sensor may be positioned at other locations on the image capture device. Multiple light sensors may be positioned at different locations on the image capture device to detect sources or locations of attenuation. Redundant light sensors of more than one type of sensor may be used at a single light sensor location to provide for validation of measurements and increase the variety of information measured.
