The invention provides a data synchronization method, device and system. A processing chip is used for receiving a scanning position indication signal sent by a laser radar, determining detection azimuth information of the laser radar according to the scanning position indication signal, and sending a first control signal to an image acquisition device according to the detection azimuth information, the first control signal being used for controlling the image acquisition device to complete exposure when the laser radar scans to the overlap area, so that a video image output by the image acquisition device is synchronized with detection data output by the laser radar. According to the technical scheme of the invention, the laser radar and the image acquisition device can obtain the data ofthe target view field at the same time, and the laser radar and the image acquisition device can synchronously obtain the data.

The invention discloses a double-arm collaborative robot control method and system for assisting oral medical images. The system comprises a collaborative robot, a motion controller of the collaborative robot, an image bulb tube clamping mechanism, a photosensitive plate tail end clamping mechanism, an oral cavity posture detection module, an oral cavity posture detection sensor, a human-computer interaction interface and a server. A collaborative robot clamped by a tail end light sensing plate is used for tracking an intraoral tooth position of a patient, so that the tail end clamping is made to be close to a focus area as much as possible, and precise positioning and self-adaptive dynamic tracking are carried out; and based on the control method of multi-modal information, the collaborative robot is used for being close to a shooting part to assist image operation, and the image bulb tube is controlled to perform shooting operation by comparing and matching the signals reflecting the image parameters. The system can realize automatic tracking of the focus tooth position, solves the problems of poor consistency and exposure stability in the oral cavity imaging process, and effectively reduces virus cross infection caused by contact between doctors and patients.

The invention provides a safety monitoring method, an electronic device, an air conditioner and a computer readable storage medium. The method comprises the steps of obtaining first depth data corresponding to a detection area detected by a depth camera; judging whether a target behavior appears in the detection area according to the first depth data; and if the target behavior appears in the detection area, executing a preset processing operation. The depth data is collected through the depth camera to avoid exposure of indoor environment information and image information of the user, so that the influence on user privacy during data leakage is avoided, and meanwhile, the target behavior can still be monitored based on the data.

The embodiment of the invention provides direct plate making equipment which is used for improving the plate making efficiency. According to the direct plate making equipment, clamping assemblies used for clamping a screen frame are divided into the multiple sets, all the sets are connected with the different and independent air path channels, and an air path control system controls the screen frame clamping state of all the sets of clamping assemblies by controlling the air pressure in the air path channels, so that a plurality of screen frames can be clamped in one plate making process, and one equipment can perform exposure imaging on photosensitive material coatings on the plurality of screen frames at the same time, and the plate making efficiency is greatly improved.

The invention discloses an exposure batch control method and system. The method comprises the following steps: obtaining exposure energy of a product batch which is currently operated in exposure equipment; obtaining exposure energy and alignment precision of subsequent product batches; when the exposure energy of the currently operated product batch is greater than the reference energy and the exposure energy of the subsequent product batches is less than the reference energy, arranging the subsequent product batches with the characteristic value of alignment precision greater than or equal to the reference value into a first queue, and arranging the subsequent product batches with the characteristic value of alignment precision less than the reference value into a second queue; the higher the characteristic value of the alignment precision is, the lower the requirement on the alignment precision is; and performing operation on the operation sequence of the subsequent product batches according to the sequence of firstly operating the first queue and then operating the second queue. According to the invention, when the exposure energy of the currently operated product batch is determined to be relatively high, the product batch with low requirement on the alignment precision in the subsequent product batches is operated preferentially, so that the aberration problem is avoided, and the yield of a production line is improved.
