Abstract
A processor measures a first distance to an object in a distance measurement target region on the basis of an irradiation timing when a light irradiator performs surface irradiation on the distance measurement target region with light and a light receiving timing when a light receiver receives reflected light of the light from distance measurement target region. In a case in which a specific pixel included in the light receiver generates a plurality of signals at different timings within a light receiving period corresponding to the surface irradiation by the light irradiator, the processor measures the first distance on the basis of a relationship between the plurality of signals.
Claims20
An information processing device comprising:
- a processor;
- and
- a memory that is connected to or provided in the processor,
- wherein the processor is configured to:
- measure a first distance to an object in a distance measurement target region on the basis of an irradiation timing when a light irradiator performs surface irradiation on the distance measurement target region with light and a light receiving timing when a light receiver receives reflected light of the light from the distance measurement target region;
- and
- in a case in which a specific pixel included in the light receiver generates a plurality of signals at different timings within a light receiving period corresponding to the surface irradiation, measure the first distance on the basis of a relationship between the plurality of signals above a reference threshold value generated by the specific pixel.
An information processing method comprising:
- causing a light irradiator to perform surface irradiation on a distance measurement target region with light;
- causing a light receiver to receive reflected light of the light from the distance measurement target region;
- and
- measuring a first distance to an object in the distance measurement target region on the basis of an irradiation timing when the light irradiator performs the surface irradiation on the distance measurement target region with the light and a light receiving timing when the light receiver receives the reflected light,
- wherein, in a case in which a specific pixel included in the light receiver generates a plurality of signals at different timings within a light receiving period corresponding to the surface irradiation, the first distance is measured on the basis of a relationship between the plurality of signals above a reference threshold value.
A non-transitory computer readable recording medium storing a program that causes a computer to execute a process comprising:
- causing a light irradiator to perform surface irradiation on a distance measurement target region with light;
- causing a light receiver to receive reflected light of the light from the distance measurement target region;
- and
- measuring a first distance to an object in the distance measurement target region on the basis of an irradiation timing when the light irradiator performs the surface irradiation on the distance measurement target region with the light and a light receiving timing when the light receiver receives the reflected light,
- wherein, in a case in which a specific pixel included in the light receiver generates a plurality of signals at different timings within a light receiving period corresponding to the surface irradiation, the first distance is measured on the basis of a relationship between the plurality of signals above a reference threshold value.
