The light projecting system includes a laser light source to project coherent light and a diffractive optical element having a plurality of layers that are etched to form binary step patterns, wherein the plurality of layers is configured to split the coherent light into a plurality of beams of light, wherein each beam of light forms one point of the pattern, and wherein the plurality of layers is further configured to control divergence angles of the beams. The example distance sensor further includes a light receiving system to capture an image of the pattern projected onto the object and a processor to calculate a distance to the object based on an appearance of the pattern in the image and on knowledge of trajectories of the points of light.

Abstract: In an example, an apparatus includes a first sensor, a second sensor, and an integrated management system. The first sensor is for capturing a first set images of a calibration target that is placed in a monitored site, wherein the first sensor has a first position in the monitored site, and wherein a physical appearance of the calibration target varies when viewed from different positions within the monitored site. The second sensor is for capturing a second set of images of the calibration target, wherein the second sensor has a second position in the monitored site that is different from the first position. The integrated management system is for determining a positional relationship of the first sensor and the second sensor based on the first set of images, the second set of images, and knowledge of the physical appearance of the calibration target.

Abstract: An example apparatus includes a light projecting system, a light receiving system, and a controller. The light projecting system projects beams of light of a wavelength that is invisible. The beams form a pattern on a surface when the beams are incident upon the surface. The light receiving system acquires an image of the pattern on the surface. The controller calculates a distance to the surface based on the image. The light receiving system includes a lens, an imaging sensor, and a bandpass filter. The imaging sensor includes a first subset of photodetectors sensitive to wavelengths of light that are visible and a second subset of photodetectors sensitive to the wavelength of light that is invisible. The bandpass filter includes a first passband whose range corresponds to the wavelengths of light that are visible and a second passband whose range corresponds to the wavelength of light that is invisible.

Abstract: A projection pattern is projected onto a surface of an object from a projection point of a distance by projecting a plurality of beams of light from the projection point. The plurality of beams of light creates a plurality of projection artifacts that is arranged in a grid on the surface of the object. A center projection artifact lies at an intersection of a grid longitude line and a grid latitude line. A projection of the plurality of beams is adjusted so that the longitude line and/or the latitude line is rotated by a predetermined amount from an original position to a new position, resulting in an adjusted projection pattern on the surface of the object. An image of the object, including at least a portion of the adjusted projection pattern, is captured. A distance from the distance sensor to the object is calculated using information from the image.
