1. A measurement apparatus mountable on a movable apparatus, the measurement apparatus comprising:
a first imager and a second imager,
wherein the first imager is disposed closer to a road surface than the second imager,
wherein a first image capture range of the first imager and a second image capture range of the second imager at least partially overlap at the road surface, which is an imaging target,
wherein a traveling direction of the moveable apparatus is defined as the X-direction, a width direction of the moveable apparatus is defined as the Y-direction, and the vertical direction of the moveable apparatus is defined as the Z-direction,
wherein an inclination angle “θ2” of the first imager with respect to a width direction of the movable apparatus, the Y-direction, is defined by a first image capture direction of the first imager and a perpendicular line between the first imager and the road surface, wherein the perpendicular line is parallel to the Z-direction, and
wherein a second image capture direction of the second imager is parallel to the perpendicular line between the first imager and the road surface.
