1. A vehicle comprising:
a vehicle body;
a light detection and ranging (LiDAR) device configured to operate in a first operation mode and a second operation mode in which a power consumption per unit time is lower than a power consumption per unit time of the first operation mode; and
a controller;
wherein the controller is configured to:
transmit a first trigger signal to the LiDAR device when a state of the vehicle is changed from a first state to a second state; and
transmit a second trigger signal to the LiDAR device when the state of the vehicle is changed from the second state to the first state;
wherein the LiDAR device is configured to:
