The invention relates to a laser radar, in particular to a double-steering-engine scanning laser radar which comprises a laser radar, a first-stage steering engine, a second-stage steering engine and a controller. The laser radar is used for data acquisition; the first-stage steering engine is connected with the second-stage steering engine and is used for driving the second-stage steering engine to swing in a stepping manner, and the swing direction of the first-stage steering engine is set to be a Y axis; the second-stage steering engine is used for driving the laser radar to step, the stepping swing direction of the second-stage steering engine is set as an X axis, and the X axis and the Y axis are in an orthogonal relation; the controller is used for controlling the work of the first-stage steering engine and the second-stage steering engine, receiving the data of the laser radar and processing the data to obtain a result. According to the embodiment of the invention, the double steering engines are adopted to perform stepping swing to drive the laser radar to scan an object point by point to obtain the data of the object, and then the data is processed to obtain the volume of the object. The system not only solves the problem that a single-point laser radar cannot accurately measure in an object volume measurement scheme, but also has the advantage of lower cost.
Description
technical field [0001] The disclosure of the present invention relates to a laser radar, in particular to a dual steering gear scanning laser radar and a volume measurement method based on the radar. Background technique [0002] The existing volume detection technology usually obtains the density and weight of the object, and the volume can be calculated by using the formula M = pV. The density of the object is measured by a special equipment density meter, and the weight of the object is obtained by a load cell; when the object or weight cannot When directly obtained, it is necessary to use laser radar to detect the volume of the object. The existing detection methods use laser radar into two types, single-point laser radar and area array laser radar. Single-point laser radar is estimated based on the distance measurement of a point The volume of the entire object, this method is suitable for regular objects, and the error of irregular objects is extremely large; area arra...
