摘要： 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.

摘要： An illumination apparatus 22 illuminates probe light L1. A gating camera 20 captures an image for each of image capture ranges divided in the depth direction. A camera controller 26 controls a timing at which the illumination apparatus 22 illuminates the probe light L1 and a timing at which an image sensor 24 is exposed such that each slice image IMGs output from the image sensor 24 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 28 generates a final image IMGf including the entire object of interest based on the multiple slice images IMGs that correspond to the multiple image capture ranges RNG.

摘要： This measurement device (1) comprises: a light emitting unit (10) that emits pulsed light; an imaging sensor (22) that outputs a signal value corresponding to an amount of exposure for each pixel (221); a timing control unit (32) that exposes reflected light to the pixel (221) of the imaging sensor (22) during an exposure period of an exposure width (Gw) which is set in accordance with an area to be measured and is shorter than a pulse width (Lw) of the pulsed light; and a calculation unit (36) that calculates an arrival time (Tx) of the reflected light, on the basis of the signal values (Sa to Sd) corresponding to the three or more consecutive exposure periods (A to D) that can include the pulse width (Lw).

摘要： A gating camera 100 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 110 emits illumination light L1. A camera controller 130 controls a light emission timing of the illumination apparatus 110 and an exposure timing of an image sensor 120 so as to generate slice images from a near slice to a farther slice. An arithmetic processing device 140 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.
