Apparatus, method for distance measurement, and non-transitory computer-readable storage medium

A method for distance measurement, the method comprising:

• executing, by processor circuitry, a detection process that includes detecting a measurement target in a measurement range through two-dimensional scanning of a scan angle range with laser light, and
• executing, by the processor circuitry, a changing process that includes changing a width of the scan angle range with the laser light so that sampling density has a certain value or higher based on a distance and a bearing angle from the apparatus to the measurement target.

A non-transitory computer-readable storage medium storing a program that causes processor circuitry to execute a process for distance measurement, the process comprising:

• executing a detection process that includes detecting a measurement target in a measurement range through two-dimensional scanning of a scan angle range with laser light, and
• executing a changing process that includes changing a width of the scan angle range with the laser light so that sampling density has a certain value or higher based on a distance and a bearing angle from the apparatus to the measurement target.
