Title: Determination device, determination method, and determination program
IPC: G08G1/00
Filed: 2021-10-19
Abstract: PROBLEM TO BE SOLVED: To provide a determination device that enables accurate determination of a slope (gradient) of the ground. 
     SOLUTION: A determination device acquires light-receiving information obtained by receiving reflected light from the ground of light emitted from a vehicle to the surroundings, and detects a slope of a reflection point of the light based on the light-receiving information. Threshold information indicating a threshold value for determining the type of the slope is obtained from a map database 17 that records the threshold information in association with map information corresponding to the ground. Based on the comparison between the threshold value indicated by the threshold information and the slope, it is determined whether the reflection point is the ground or an object on the ground.
