Abstract: A gating camera divides a field of view in a depth direction into multiple slices, and generates multiple slice images that correspond to the multiple slices. An illumination apparatus emits illumination light. A camera controller controls a light emission timing of the illumination apparatus and an exposure timing of an image sensor so as to generate slice images from a near slice to a farther slice. An arithmetic processing device judges whether a road surface appears for each of the slice images generated in sequence. Processing for a row judged to include a road surface in a given slice is simplified at the time of sensing of a slice farther than the given slice.

Abstract: A gating camera divides a field of view in a depth direction into multiple ranges, and generates multiple slice images that correspond to the multiple ranges. A controller is configured to generate an emission control signal and an exposure control signal. An illumination apparatus emits probe light according to the emission control signal during normal imaging. An image sensor performs exposure according to the exposure control signal. A calibration light source emits calibration light to the image sensor according to the emission control signal during calibration. The controller sweeps a time difference between the emission control signal and the exposure control signal, and monitors a change in a pixel value of the image sensor during the calibration.

Abstract: A gating camera 20 divides a field of view into a plurality of ranges in a depth direction and generates a plurality of slice images corresponding to the plurality of ranges. An illumination device 22 radiates probe light L1. An image sensor 24 outputs a compressed image IMG_COMP obtained by compressing image information related to, among a plurality of lines constituting a raw image IMG_RAW obtained as a result of an exposure, an invalid line that does not contain a target. A camera controller 26 controls a light emission timing of the illumination device 22 and an exposure timing of the image sensor 24. An image processing device 28 receives the compressed image IMG_COMP from the image sensor 24, and decompresses a slice image IMG.

Abstract: A gating camera divides a field of view in a depth direction into multiple ranges, and generates multiple slice images that correspond to the multiple ranges. An illumination apparatus emits probe light. A controller controls a timing of emission of the probe light L1 by the illumination apparatus and a timing of image capture by a first image sensor and a second image sensor. The controller controls the first image sensor and the second image sensor such that they receive reflected light from different respective ranges in response to one emission of the probe light from the illumination apparatus.

Abstract: A gated camera divides a depth direction into a plurality of ranges and generates a plurality of slice images corresponding to the plurality of ranges. An illumination device radiates probe light. A controller controls a light emission timing of the illumination device and an exposure timing of an image sensor. An image processing device generates a slice image based on a sensor image transmitted from the image sensor. The image processing device selects M (M ? 2) pixel values in ascending order of pixel values for each line of the sensor image, calculates an average value of the M pixel values, and subtracts the average value from each pixel value of the corresponding line.

Abstract: An illumination apparatus illuminates probe light. A gating camera captures an image for each of image capture ranges divided in the depth direction. A camera controller controls a timing at which the illumination apparatus illuminates the probe light and a timing at which an image sensor is exposed such that each slice image output from the image sensor for each image capture range includes only an object included in the corresponding image capture range while changing the image capture range. An image processing unit generates a final image including the entire object of interest based on the multiple slice images that correspond to the multiple image capture ranges.

Abstract: A light source illuminates the FOV with pulsed illumination light having an intensity that changes with time. An image sensor is exposed to reflected light from an object in two consecutive exposures. A calculation unit generates a distance image giving consideration to the waveform of the illumination light based on the output of the image sensor acquired in the two exposures.

Abstract: An object identification system includes a camera and a processing device. The processing device includes a classifier subjected to machine learning based on the output image of the camera so as to allow it to identify an object. A gating camera divides a field of view in the depth direction into multiple ranges, and captures an image while changing the time difference between light projection and exposure for each range. The classifier is subjected to machine learning using multiple images IMG1 through IMGN generated by the gating camera as the learning data.
