Abstract
(EN)
Provided are a scanning control method, apparatus and system, a storage medium and a processor. The control method comprises: controlling a scanner to preliminarily scan a scanned object according to a predetermined path, and obtaining a scanning model of the scanned object; determining, according to the scanning model, a second predetermined position of the scanner corresponding to the scanned object at each first predetermined position; and controlling the scanner to scan, at at least some second predetermined positions, the scanned object located at the corresponding first predetermined position until a three-dimensional model is obtained. According to the control method, a scanning position of a scanner is determined according to a scanning model obtained through preliminary scanning and the position of a scanned object, and some scanning positions are selected to perform scanning, thereby avoiding crossing and repetition of a scanning range and reducing the number of instances of scanning, so that the process of scanning a three-dimensional model is simple relative to that of the prior art.

L’invention concerne un procédé, un appareil et un système de commande de balayage, un support d'informations et un processeur. Le procédé de commande consiste à : commander un dispositif de balayage pour balayer de manière préliminaire un objet balayé selon un trajet prédéterminé et obtenir un modèle de balayage de l'objet balayé ; déterminer, en fonction du modèle de balayage, une deuxième position prédéterminée du dispositif de balayage correspondant à l'objet balayé au niveau de chaque première position prédéterminée ; et commander le dispositif de balayage pour balayer, au niveau d'au moins certaines deuxièmes positions prédéterminées, l'objet balayé situé au niveau de la première position prédéterminée correspondante jusqu'à l'obtention d'un modèle tridimensionnel. Selon le procédé de commande, une position de balayage d'un dispositif de balayage est déterminée selon un modèle de balayage obtenu par balayage préliminaire et la position d'un objet balayé et certaines positions de balayage sont sélectionnées pour effectuer un balayage, ce qui permet d'éviter le croisement et la répétition d'une plage de balayage et de réduire le nombre d'instances de balayage, de telle sorte que le procédé de balayage d'un modèle tridimensionnel est simple par rapport à celui de l'état de la technique.

本公开提供了一种扫描的控制方法、装置、系统、存储介质和处理器。该控制方法包括:控制扫描仪按照预定路径对被扫描物体进行初步扫描,得到被扫描物体的扫描模型;根据扫描模型确定被扫描物体在各第一预定位置对应的扫描仪的第二预定位置;控制扫描仪在至少部分第二预定位置对位于对应的第一预定位置的被扫描物体进行扫描,直到得到三维模型。该控制方法根据初步扫描得到的扫描模型和被扫描物体的位置确定扫描仪的扫描位置,并选择部分扫描位置进行扫描,避免了扫描范围的交叉和重复,减少了扫描的次数,从而使得扫描三维模型的过程相对现有技术较为简单。
