Description

Technical Field

[0001] The present invention belongs to the technical field of intelligent detection equipment, and in particular relates to a portable intelligent detection system based on a laser sensor and a use method thereof. Background Art

[0002] The core technology of laser sensors is based on the characteristics of lasers, such as high directionality and accuracy. In the early days, it was mainly used for precision measurement in laboratories. With the breakthrough of semiconductor technology in the 1980s, the size of lasers was reduced and the cost was reduced. They were gradually applied to industrial automation, such as the size detection of mechanical parts. After the 21st century, the progress of chip technology and digital signal processing made sensors smaller and smarter, able to work stably in complex environments, and the accuracy reached the micron level. Today, it combines AI and IoT technology to not only measure distance and speed, but also recognize the shape of objects. Its application has expanded to autonomous driving (such as radar obstacle avoidance), medical equipment (such as ophthalmic scanning) and even mobile phone face recognition. Laser sensors, especially lidar and 3D laser scanners for high-precision measurement, are usually large in size and heavy in weight, and are not convenient to carry and deploy. In addition, the operation of laser sensors usually requires high-power power supply support, and the battery life of portable batteries is limited, which cannot meet the needs of long-term or remote field detection. Therefore, it is often necessary to configure additional generators or large battery packs during use, which further increases the complexity of operation. At the same time, high-precision measurements also rely on external data processing equipment, such as laptops or dedicated data acquisition systems, which further increases the carrying burden of the overall system and limits its flexibility in mobile scenarios.
