Embodiment Construction
[0024] The specific embodiments of the present invention will be described below with reference to the drawings.
[0025] A laser three-dimensional imaging system based on human-like vision principles, including a trigger 1, a pulsed laser 2, a transmitting optical module 3, a non-uniform acquisition module 5, a signal processing module 6, and a display 7.
[0026] System principle: such as figure 1 As shown, the dotted line in the figure is a light wave signal, and the solid line is an electrical signal. Trigger 1 sends a trigger signal to pulse laser 2, and pulse laser 2 sends out laser pulses. After passing through the transmitting optical module 3, it irradiates the target 4 and passes through the target 4. The reflected or scattered echo is received by the non-uniform acquisition module 5, and after being processed by the signal processing module 6, an image is displayed on the display 7.
[0027] Among them, the trigger 1, the pulse laser 2, and the transmitting optical module ...

The invention belongs to the field of laser three-dimensional imaging, and particularly relates to a laser three-dimensional imaging system based on a human-vision-based simulated mechanism. The system comprises a trigger, a pulse laser, an emitting optimal module, a non-even collection module, a signal processing module and a displayer. By adopting the non-even collection module, after a target is irradiated by the pulse laser, reflected or scattered pulse echoes pass through a first lens, a second lens and a third lens in sequence, and imaging is carried out on a probe array board. The probe array board is composed of a series of independent probes, wherein the number of probes in each ring is the same, the probes are annularly arrayed, each ring of probes and each corresponding adjacent ring of probes are in a tangent relation, adjacent pixels are in a tangent relation, the radiuses of the rings of probes increase exponentially, facula areas of the rings of probes increase exponentially, and accordingly variable-resolution-ratio target collection can be achieved; optical signals are converted to electric signals by a probe array, and the electric signals are read from inner rings to outer rings sequentially by the signal processing module in an annular switch-on mode. Fast and efficient data transmission is achieved.
Description
Technical field [0001] The invention belongs to the field of laser three-dimensional imaging, and in particular relates to a laser three-dimensional imaging system based on a visual mechanism of imitating human eyes. Background technique [0002] With the rapid development of high technology, three-dimensional vision sensors are widely used in machine vision, image monitoring, intelligent navigation and other fields because they can obtain a large amount of real-time target information. Compared with traditional two-dimensional vision sensors, laser three-dimensional imaging can not only provide the intensity image of the target, but also provide the distance information of the target, so the description of the target is richer and more accurate. However, current high-sensitivity detectors are restricted by technology, and it is difficult to realize a large area array. Therefore, scanning imaging is still the main focus at present, which makes it difficult to improve imaging eff...
