查询词典 depth of field

In the field of spaceborne remote sensing, a geometric collinearity equation of pushbroom sensor with the Kepler parameters of the satellite orbit and the attitudes of sensor has been developed. Testing the sensor model on a SPOT-5 imagery, the planimetric accuracy of object positioning is 83.392m on the ground. According to the orbital dynamical model and the kinematics model of satellite attitude, an algorithm of extrapolative location is developed. Testing the algorithm on CBERS-2 high resolution satellite imageries of central China, when the depth of extrapolation is 300km, the planimetric precision is 53.555m including the measurement errors as well as the modeling error over than the 568m which is the planimetric precision of systematic rectification.

Art should help to strengthen the depth of knowledge. In these words, we can clearly discover his idea of attaching more importance to painting itself and psychological trend of trying to avoid its sociologic meaning. In his personal career, at least up to now, he is always a person of the form. of language. As symbols he borrowed for visual expression, those desolate faces and empty facial expressions, together with colors, shadows, strokes and textures, fully unfold before our eyes the great imagination that rhythm and tune can display in the visual field.

从这样的表述中，我们应该可以清晰地看出他重视绘画本体并企图逃离社会学含义的心理倾向，至少在迄今为止的个人历程中，他一直是一个对形式语言非常关注的人，那些荒凉的面孔和空洞的表情，只不过是他的视觉表达所暂借的符号，附着在其上的色彩、影调、笔触和肌理，为我们充分展现出节奏和旋律在视觉方面所能够企及的想象力。
