Laser ranging device

A laser ranging device, comprising:

• a housing portion provided with a first light outlet and a second light outlet;
• a first laser emitting portion configured to emit a first laser along a first direction to an object to be measured, the first laser emitting portion being located in the housing portion, and an emitting end of the first laser emitting portion being opposite to the first light outlet;
• a first optical lens mounted in the first light outlet of the housing portion;
• a laser receiving portion configured to receive a reflected laser reflected by the object to be measured along the first direction, the laser receiving portion being located in the housing portion, and a receiving end of the first receiving portion being opposite to the first optical lens;
• a second optical lens mounted in the second light outlet of the housing portion;
• a second laser emitting portion configured to emit a second laser along a second direction, the second laser sequentially passing through the second optical lens and the second light outlet to form a sector-shaped laser light curtain, the sector-shaped laser light curtain being projected onto an object to be marked, and forming a zero baseline on the object to be marked, the second laser emitting portion being located in the housing portion and an emitting end of the second laser emitting portion being opposite to the second optical lens, wherein the second direction is configured to be perpendicular to the first direction;
• and
• a control portion located in the housing portion and electrically connected to the first laser emitting portion the laser receiving portion, and the second laser emitting portion.
