Basic introduction
is also known as the perceptual or three-dimensional perception. It is an individual to the unevenness of the same object or a remote reflection of different objects. The retina is a two-dimensional plane, not only can sense the planar object, but also senses objects in the three-dimensional space. The depth perception is achieved by both eyes visual. Deep perception is affected by the following factors. Physiological aspects are: binocular parallax, double eye combination, crystal adjustment, sports parallax. Objects: Object overlap, line perspective, air perspective, object texture gradient, bright and shaded and shadow, and the size of the art. According to your own experience and related clues, observe objects in a single eye can also produce deep perception. The depth of visual is visual is based on the connection formed by visual and touch in the process of individual development. Deep and distance judgment can be made by integrating activities through the brain. But the individual is not fully aware of the role of the above main and objective conditions when the individual's space relationship is spaced.

Instrumentation
Depth Perceptual Tester is a kind of instrument for research visual visual in depth. The minimum valve limit of visual errors for binding or depth can be tested. This instrument has the first and rear moving mechanism for depth, and the moving speed adjustment device can be widely used in various types of drivers, artillery, athletes, etc., the test or selection of staff-related staff, and the psychology experiment Preparation instrument.
Usage
1, the tester is situated at 2m from the standard stimulus, allowing both the grain or a single grade to the observation window, and observe the front and rear movement of the more stimulus.
2, the primer is turned on, open the light. At this time, it is more stimulating automatic leaving standard stimulus to stop. If during the test, the power switch is always on a state, then the main trick can press the reset button to make the compare stimulus in the initial position, i.e., the farthest stimulation of the standard.
3, by the subject operates the remote control button, so that the comparative stimulus is three o'clock in line.
4, the host observes the measurement error of the tester from the tester from the scale reading.
Precautions
1, the instrument should be placed in a ventilated, dry environment, and avoid direct sunlight and dust.
Application value
The famous visual cliff experiment description, the baby who has just climbed has a considerable deep perception. Domestic Guo Jingqiu et al. The three-dimensional visuality of children aged 3 to 12 years agreed, and considered that stereoscopic maturity was previously 3 years old. Some children have a deep perception of defects, such as intermittent outer tide children's patients, and their close three-dimensional perspective, far-sighted perspective, high-profile perspective, have a large improvement in early surgery, and check the three-dimensional dependent distances of different distances. Important indicators for investigation. In addition, Scholars' research results show that the learning obstacle (LD) children's deep feelings have lack of clues to utilize the ability, and there is a potential association with emotional judgment, further proves that Johnson et al. [5] mentioned that simple perceived judgment often reflects deep complex society. Perceptual capacity, spreading roads for deep perception of cognition.
In the industry where high-speed motion needs to have a sound stereoscopic function, sports operators are also self-evident. When choosing the training athlete, the traditional experience and selection organization personnel, the assessment of the coaches is indispensable, but the application of modern technology, scientific selection methods, and inspection of stereo vision is essential. Ball, fencing, diving, shooting, gymnastics such as relatively static chess, weightlifter, more highcoming athletes need good stereoscopic visual, if they do not do a three-dimensional visual inspection, if they do not make a stereoscopic test, it is likely to miss Three stereo visual abnormalities will cause dual waste. Studies have shown that training of individual deep perception can effectively improve the effects of ball teaching and training. Some researchers put forward recommendations on the training of deep perception accuracy of football referees. It is also recommended to test its depth visual threshold when it is recommended to select a basketball player according to its research.
Deep Perneessility is also widely used in many occupations that require higher visual attention. If the vehicle driver's view depth is significant and safe driving status; deep perception has a good discrimination for seafarers; the measurement of different color depth visual appendix values under dynamic conditions is a problem; forces personnel Functional status is good; stereoscopic examination is performed, and the quality of the warrior soldiers is very necessary.
Depth Perchaens is already very common in the computer, such as artificial intelligence, 3D interface, etc. In decades of development, computer stereo visual has formed its own method and theory.
