Description
Technical Field
[0001] The utility model relates to the technical field of vehicle surface measurement, in particular to a device for measuring the protruding dimensions of vehicle outer surface parts. Background Art
[0002] Vehicle surface measurement is the precise measurement and analysis of features such as size, shape, and curvature on a vehicle's exterior surface. Vehicle surface measurement typically utilizes a variety of high-precision measurement tools and technologies, such as 3D scanners, laser rangefinders, and optical measurement systems. These tools and technologies enable the acquisition of three-dimensional data of the vehicle's exterior surface, enabling further development in design verification, quality control, and custom modifications. Vehicle surface measurement plays a vital role in the automotive industry, helping to ensure that the vehicle's exterior quality and performance meet design requirements.
[0003] Currently, when measuring the outer surface of a vehicle, a scanner is mostly used to scan and then a three-dimensional model of the vehicle is obtained through computer analysis. When measuring the outer surface of a vehicle, a staff member generally walks around the perimeter of the vehicle body with a handheld scanner to scan. When the handheld scanner is used to scan the outer surface of the vehicle, the scanning route will not be fixed due to the error of manual movement, and then a certain error will be generated when the scan data is input into the computer for analysis. Some vehicle scanning technologies are to set up a movable gantry on the ground, install a scanner or scanning device on the gantry, and then set a guide rail at the bottom of the gantry so that the moving gantry drives the scanner to scan the outer surface of the vehicle. This scanning method is also prone to scanning errors, which makes the processing of scanned data more difficult. Based on this, a device that can move stably is needed to scan the outer surface of the vehicle to ensure the accuracy of the scanned data. Utility Model Content
