The distance measurement system includes an emitter emitting light, a receiver having a pixel array at which are formed a plurality of pixels detecting light reflected from an object, a processor configured to calculate distance data relating to a distance to the object for each of the plurality of pixels based on a result of detection of the reflected light, and use the distance data to generate a distance image, and a vehicle information detector detecting vehicle information relating to behavior of the vehicle. The processor calculates the distance data a plurality of times based on results of detection of light reflected from the object in a plurality of different time periods. The processor converts coordinates of the distance data based on the vehicle information to correct positional deviation between the distance data on the pixel array and generates the distance image for an overlapping range of the distance data.

Distance measurement system

A vehicle includes a distance estimation device that estimates the distance from the vehicle to a traffic light. The distance estimation device includes an image acquisition unit that acquires an image captured by a camera for imaging the surroundings of the vehicle, a light size acquisition unit that acquires a light size of a light of the traffic light reflected in the image, and a distance estimation unit that estimates the distance from the vehicle to the traffic light based on the light size. The light size acquisition unit removes flare of the light in the image, and acquires the light size in the image after the flare is removed.

Distance estimation device

An image processing device includes one or more processors configured to: recognize a category of an object within a range of a predetermined distance with respect to a vehicle based on a detection result of a sensor, the sensor including an image sensor; decide the number of images subjected to image processing per unit time based on the category of the object recognized by the one or more processors; acquire, from the image sensor, a plurality of images obtained by continuously shooting the object as a subject; select one or more target images from among the images acquired by the one or more processors based on the number of images subjected to the image processing per unit time decided by the one or more processors; and calculate information regarding the object based on the one or more target images.
