1. An environment sensing system comprising:
a laser detection module, the laser detection module including a first laser module, a second laser module, a third laser module, and a fourth laser module, a field of view (FOV) angle of each laser module being less than or equal to 120°, wherein
the first laser module and the second laser module are disposed on a front side of a movable platform to detect an area in front of the movable platform, the FOVs of the first laser module and the second laser module partially overlap;
the third laser module and the fourth laser module are respectively disposed on both sides of the movable platform to detect a front left area and a front right area of the movable platform;
an overlap percentage of the FOV of the first laser module and the second laser module is greater than 30% of the FOV of the first laser module or the second laser module;
the overlap percentage of the FOV of the third laser module and the first laser module is greater than 10% of the FOV of the third laser module or the first laser module; and
the overlap percentage of the FOV of the fourth laser module and the second laser module is greater than 10% of the FOV of the fourth laser module or the second laser module.
