Embodiment

[0048] Such as figure 1As shown, the present embodiment proposes a high-precision measurement system for the size of a truck compartment, including a gantry 1 with a machine head, a servo motor 2 installed on the head of the gantry 1, and mounted on the gantry 1 through a connecting piece 10. A three-dimensional measuring device 3 on the servo motor 2, and a data processing system (not shown) connected with the servo motor 2 and the three-dimensional measuring device 3;

[0049] A ground guide rail S is formed between the gantry 1 and the ground for parking the truck 4 to be measured;

[0050] The servo motor 2 is used to drive the three-dimensional measuring device 3 to rotate through rotation, and feed back the angle value of the rotation to the data processing system; wherein, the servo motor 2 forms a certain angle with the rotating surface of the three-dimensional measuring device 3, preferably 90° ° Angle. as described figure 2 As shown, the connector 10 includes a f...

Abstract

The present invention provides a high-precision measurement system and method for the size of a truck compartment. The measurement system includes a gantry, a servo motor, a three-dimensional measuring device and a data processing system; a ground guide rail S is formed between the gantry and the ground for parking to be measured Truck; the servo motor is used to drive the three-dimensional measuring equipment to rotate through rotation, and feeds back the angle value of the rotation to the data processing system; wherein, the servo motor forms a certain angle with the rotating surface of the three-dimensional measuring equipment; the three-dimensional measuring equipment is used to measure the truck Carry out scanning measurement, and send the measured distance value to the data processing system; the data processing system is used for the angle value of the rotation fed back by the servo motor according to the angle between the servo motor and the rotating surface of the three-dimensional measuring equipment, and the three-dimensional measuring equipment The measured distance value is used to calculate the compartment geometry of the truck to be measured. The invention realizes a high-precision measurement system for the size of the truck compartment with simple structure, low cost, high precision and fast measurement.

Description

technical field [0001] The invention relates to the technical field of vehicle measurement, in particular to a high-precision measurement system and method for the size of a truck compartment. Background technique [0002] There are two non-contact measurement methods for existing truck compartment dimensions: [0003] The first one uses multiple point laser range finders to measure the length, width and height of motor vehicles, especially the compartments of trucks. Due to the singleness of the data of the point laser rangefinder, it is impossible to perform fully automatic, high-precision, and fast measurement for complex truck compartment scenes; [0004] The second is multi-3D measurement equipment collaborative measurement, but the scanning cost of multiple 3D measurement equipment is high, the system is complex, installation is difficult, the environmental space requirements are high, and radars will interfere with each other, resulting in difficult deployment and po...
