Description

[Technical Field]

[0001] This utility model belongs to the field of machinery, and specifically relates to a handheld contour detection device. [Background Technology]

[0002] Laser measurement devices have been widely used in industry for detecting object contours. However, most of these applications focus on measuring small parts and are typically fixed on production lines for real-time measurement. For the detection of large or specialized structures, these devices are insufficient. Therefore, a handheld contour detection device is needed. Existing handheld contour detection devices usually utilize optical scanning principles and triangulation to measure the object's contour dimensions, and then make corresponding judgments, such as defect detection. Thus, existing handheld contour detection devices typically include a light emitter, an image acquisition device (such as a CMOS or CCD image acquisition chip), optical lenses, and supporting main circuit boards and image processing circuit boards. Therefore, how to meet basic functional requirements while minimizing the overall size of the handheld contour detection device and achieving a simple installation structure remains a problem that the industry needs to continuously solve.
