Image target detection method and device and camera equipment

Abstract

The invention discloses an image target detection method and device and camera shooting equipment, which are used for improving an existing detector so that the existing detector can flexibly adapt to different detection ranges and meet different product requirements. The method comprises the following steps: determining a current application scene of a preset detector, and obtaining a corresponding configuration file according to the application scene; acquiring a to-be-detected image; reading a position relationship from the configuration file, wherein the position relationship is a position relationship between the sub-region of the preset detector in the application scene and the to-be-detected image; dividing the to-be-detected image according to the position relationship to obtain sub-images corresponding to the sub-regions; performing target detection on the sub-image through the preset detector to obtain a detection result; and processing the detection result to obtain a target detection result of the to-be-detected image.

Description

technical field [0001] The present application relates to the technical field of image detection, and in particular to an image object detection method, device and camera equipment. Background technique [0002] Nowadays, target detection applications based on face detection, head detection, pedestrian detection, and vehicle detection are very common. Target detection technology is widely used in consumer electronics, smart terminals, commercial displays, transportation, security and other fields. Most target detection algorithms are based on deep learning, and the corresponding deep learning models are usually trained based on specific data sets or specific scenarios. Once deployed, their specifications (such as detection accuracy, detection distance) and the scenarios they can handle are determined. of. In actual application scenarios, the same company may have multiple products or multiple functions of the same product that require the same target detection algorithm, bu...

However, the former is time-consuming and laborious, with high R&D costs and a long cycle, while the latter is extremely difficult to train and may not even be feasible. Even if it can meet the effect, its performance is often unbearable for most mobile devices, especially low-end embedded platforms.

[0004] To sum up, if the product demand changes, it will take time and effort to select and train a new detector. For the demand of a larger scale range, it is difficult to train a new detector. Even if it is trained, the computational overhead will inevitably be very high. Compared with the original detector, the single frame detection time will be greatly increased. For the low-end embedded platform, the corresponding calculation speed and detection frame rate will be greatly reduced.
