Embodiment Construction

[0048] Such as figure 1 As shown, in the first embodiment of the method for measuring the three-dimensional shape of the object of the present invention, the following steps are included:

[0049] S101. Place the object to be measured on or completely surrounded by a flexible substrate with a set thickness, so that the flexible substrate produces a deformation corresponding to the three-dimensional shape of the object to be measured. Among them, the flexible substrate can be based on various flexible materials such as sponge, silica gel, and multi-layer cloth, so that when the measured object is placed on it or completely wrapped, it can produce sufficient deformation, or when the measured object leaves time to return to its original state.

[0050]S102. Collect the deformation of the flexible substrate through the sensor array, and generate sensor sensing data. Wherein, the sensor array includes one or more sensor matrices arranged on or in the flexible substrate. When the...

Abstract

The invention relates to a three-dimensional object shape sensing method, device and system. The method includes the steps: S1, placing a detected object on a flexible substrate with a set thickness or completely wrapping and clamping the detected object with the flexible substrate with the set thickness, and enabling the flexible substrate to generate deformation corresponding to a three-dimensional shape of the detected object; S2 acquiring deformation of the flexible substrate through a sensor array to generate senor sensing data; S3 generating sensor array data according to the senor sensing data to obtain three-dimensional shape data and motion state data of the detected object or combination of the three-dimensional shape data and the motion state data. According to the method, the deformation of the flexible substrate is acquired by the sensor array, the senor sensing data are generated, the sensor array data are generated according to the senor sensing data, so that the three-dimensional shape data and the motion state data of the detected object or combination of the three-dimensional shape data and the motion state data are acquired, a complicated vision system and a measuring instrument are omitted, and the method has the advantages of simplicity and rapines in measurement.

Description

technical field [0001] The invention relates to the field of object three-dimensional shape sensing, in particular to a method, device and system for sensing the three-dimensional shape of an object. Background technique [0002] In many occasions, people need to quickly obtain the approximate size of an object or the shape change data of an object in motion, so that people can quickly judge the size and shape of the object, or study the change of its motion shape. For example, the identification of fruit size and shape in agriculture; in some industrial designs, when it is necessary to simulate or imitate certain objects, it is often necessary to measure the external dimensions of the object; or, in some art designs, it is also necessary to know the approximate size of the object. shape. In addition, some good applications can also be produced in some toys, animation, and medical fields. For example, it is still difficult to extract the dynamic change data of a mouse durin...
