Three-dimensional imaging system based on TOF

Abstract

The invention discloses a three-dimensional imaging system based on TOF. The three-dimensional imaging system comprises a laser emitting module, a photosensitive sensor, an ARM processor module, an FPGA processing module, a memory module, a gigabit network port, a display module and a temperature sensor. According to the three-dimensional imaging system, an infrared light beam is emitted by emitting an active light source, a light signal is reflected back when encountering an obstacle along the propagation direction and is received through a lens, the influence of ambient light is filtered, and the photosensitive sensor is used for sensing the position and the distance of a target by receiving the amount of returned light. According to the three-dimensional imaging system, three-dimensional imaging of the target within ten meters can be realized, and high measurement precision can be realized; moreover, the system has a far measurement range, can adapt to the influence of certain ambient light while ensuring the measurement precision, and can obtain high frame rate; and the system is simple, effective and easy to use.

Description

technical field [0001] The invention belongs to the field of three-dimensional imaging and laser radar, relates to three-dimensional imaging technology, in particular to a TOF-based three-dimensional imaging system. Background technique [0002] Three-dimensional images can not only obtain plane image information but also obtain depth information, and have a wide range of application scenarios. Commonly used 3D image imaging methods include binocular and structured light solutions. This scheme can obtain higher resolution and measurement accuracy, but the measurement distance is relatively short, and it is greatly affected by ambient light. Existing TOF-based 3D image imaging methods have complicated circuit design and compensation process, complex calculations, difficulty in obtaining a high frame rate, and are easily affected by background light. Based on mechanical scanning laser radar, the structural design is very complicated. [0003] In order to solve the above dra...
